Calcified Gastric Carcinoma Radiologically visible calcifications in primary gastric cancer are rare and are usually seen in mucinous adenocarcinoma (, 27 28). Mucinous adenocarcinoma is characterized by prominent glandular formations and abundant mucin deposition, nearly all of which is extracellular (, 4) Calcification in the wall of a mass such as a cyst, pseudocyst or aneurysm. Hallmark is a smooth curvilinear rim of calcification: simple serous cysts. aneurysms e.g. splenic or renal arteries. echinococcal cysts. organizing hematoma. 'porcelain' gallbladder. calcified appendiceal mucocele Actually, however, grossly calcified gastric leiomyomata are exceedingly rare. A review of more than fifty articles on smooth-muscle tumors of the stomach revealed a single case similar to the one to be recorded here, that of Heitz (2), reported in 1902. His description (in part) follows: The tumor lies in the posterior wall... Dr Mohammad Taghi Niknejad and Assoc Prof Frank Gaillard et al. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. They account for ~5% of all sarcomas, and are mostly found within stomach and mid-distal small bowel. They respond remarkably well to chemotherapy
Calcified mediastinal lymph nodes (differential) Dr Yuranga Weerakkody and Assoc Prof Frank Gaillard et al. There are numerous causes of calcified mediastinal lymph nodes. Common causes include: infectious granulomatous diseases. tuberculosis. histoplasmosis. sarcoidosis Epidemiology. Mesenteric cysts are rare, with a reported incidence of 0.5-1 per 100,000 admissions 3.. Clinical presentation. Patients usually present with abdominal pain and/or mass, although the cysts can be asymptomatic, incidental finding 3.. Patholog resulting in abdominal pain, fullness, throm-bosis, and fibrosis or have focal stromal cal-cifications, which are frequently coarse and large [30, 33] (Fig. 4). Calcifications are vi-sualized in 10-20% of hemangiomas and CT of Liver Calcifications and Calcified Liver Masses Radiology
Malignant GIST's predominantly grow extraluminally and can show necrosis, hemorrhage, calcification (post therapy) and fistula formation. Typically a GIST is a well defined and exophytic mass with heterogeneous enhancement and a clear delineation from the mesentery. An intraluminal mass is far less common The Bosniak classification was described in 1986. This classification helps the radiologist to categorize each cystic renal mass as nonsurgical (ie, benign in category 1 and 2) or as surgical (ie, requiring surgery in category 3 and 4). After the original description, it became obvious that there were some category II cysts that were. This was interpreted as a calcified abdominal mass prior to obtaining a lateral chest radiograph, which showed it to be a jointed extension from the normal xiphoid process. In the other two cases, the mass was recognized on ultrasound as a jointed xiphoid process. Awareness of this important normal variant can prevent unnecessary surgery Most benign GISTs are not diagnosed on abdominal radiographs, but a large tumor in the stomach can occasionally be recognized as a soft tissue mass indenting the gastric air shadow. Rarely, benign GISTs in the stomach contain irregular streaks or clumps of mottled calcification that are visible on abdominal radiographs, barium studies, or.
The abdominopelvic CT showed multiple intraperitoneal abdominal and pelvic masses, partially calcified and associated with intraperitoneal effusion (Figure 1). The histological diagnosis retained following a CT scan was that of calcified peritoneal metastases of papillary carcinoma of the thyroid gland 1. Radiology. 1981 Oct;141(1):83-6. Amputated calcified ovaries in children. Kennedy LA, Pinckney LE, Currarino G, Votteler TP. A calcified abdominal mass was an identical finding in four asymptomatic girls, ages 2 weeks to 9 years. At laparotomy the right ovary was absent, and in three patients the ipsilateral oviduct was at least partially. Plain abdominal X-ray (Fig. 1) revealed a rounded calcified pelvic lesion and a dysplastic left hip. Contrast-enhanced CT scan (Fig. 2) revealed a calcified cystic lesion seen in the anterior superior aspect of the bladder. There was no discernible fat plane between the mass and the bladder - suggesting invasion
Abdominal radiograph (Figure 1) demonstrates increased soft-tissue density in the right abdomen with displacement of bowel gas,which is suspicious for an underlying mass. Contrast-enhanced computed tomography (CT) of the abdomen and pelvis (Figure 2) shows a multilocular fluid-density retroperitoneal mass that fills the right abdomen and. These also showed a calcified heterogeneous mass in the mid-abdominal region, which was further characterized by CT as a lithopedion (calcified ectopic pregnancy). This is one of the few cases studied on a MDCT equipment, and it clearly enhances the post-processing abilities of this imaging method which allows diagnostic high-quality MIP images
Aneurysm - calcified. Occasionally the walls of an abdominal aneurysm are calcified such that they become visible on X-ray. Large aneurysms such as this may or may not be symptomatic, but either way should be brought to the attention of the vascular surgeons Causes of Calcified Liver Masses on CT. 1- Inflammatory hepatic lesions. o Most common cause of calcified hepatic lesions. . Inflammatory conditions. For example, granulomatous diseases (tuberculosis). Calcification involves entire lesion. Appears as a dense mass.
The computed tomographic (CT) and ultrasonographic (US) appearances of retained surgical sponges are described. In each case, the presence of a sponge was confirmed at repeat operation. CT examinations were performed in nine patients. In six cases, a low-density mass was demonstrated; in two cases, loss of inner cortical bone margin. loss of lamina dura of teeth. low-set ears. lower abdominal calcification. lower abdominal mass in a neonate or child. lower lung disease. lucent bone lesion with sclerotic rim. lucent defect in bones of hands, wrists, feet, or ankles. lucent lesion of the calcaneus Imaging: solid mass, often grow beyond adrenal, displacing kidney, crossing midline and encasing abdominal vasculature, extends into neural foramina CT : 80% calcified DDX : neuroblastoma, ganglioneuroblastoma, ganglioneuroma - differ in malignancy potential with neuroblastoma being the most malignant and ganglioneuroma being essentially benig A 56-year-old male was referred to our urology clinic for a renal mass. This was initially identified incidentally on a plain film radiograph of the lumbar spine as a spherical abdominal mass. Treatment with nephrectomy confirmed it as a cystic clear-cell renal cell carcinoma Calcified fibroids are the most common lower abdominal calcific masses in women. They are often flocculent radio densities with radiolucencies within of variable size ([ Fig. 13 ]). Fig. 13 Radiograph of pelvis reveals rounded pelvic masses with popcorn calcification suggestive of calcified fibroids
It most commonly occurs in male infants as a palpable abdominal mass, and must therefore, be distinguished from more common causes of abdominal masses in children. Radiologic evaluation can demonstrate the gastric origin of the mass and specific features of teratomas such as fat and calcification, which help to exclude other palpable masses. Gastric Deformity from Extrinsic Pressure by Calcified Splenic Artery Gastric Deformity from Extrinsic Pressure by Calcified Splenic Artery Rosenberg, Murray A.; Elkin, Milton 1957-11-01 00:00:00 men in elderly patients. The celiac trunk branches from the abdominal aorta just below the aortic hiatus in the diaphragm and divides into three branches close to its origin Click for pdf: Abdominal Mass General Presentation An abdominal mass in a neonate, young child, or adolescent patient is something that every pediatrician needs to be wary of as these masses can indicate malignancy. The differential for an abdominal mass can be extensive and quite daunting, as it incorporates many systems including the gastrointestinal (GI), [ Lithopedion is a rare phenomenon resulting from an extra-uterine pregnancy that advances to fetal demise and calcification and there are less than 300 cases reported in 400 years of medical literature. This rare condition was first described by a surgeon of the Arabic era of medicine in the 10th century. This case report is a 26-year-old, multiparous woman who had presented a lower abdominal.

Peritoneal carcinomatosis. Gadolinium-enhanced MR image with fat saturation shows a thin rim of abnormally enhancing peritoneum in the right and left subphrenic spaces (arrows). Ascites is present Calcification is occasionally observed in tumors, regardless of the organ or type of tumor. It is a notable radiologic feature and one that potentially has clinical significance, since the identification of intratumoral calcification facilitates detection of the tumor as well as its differential diagnosis (1, 2).In the abdominopelvic cavity, various kinds of tumors such as, for instance, mucin. The scan (Fig. 4) better defined the character of the calcified mass, and the obvious diagnosis was confirmed with a conven- tional radiograph of the abdomen and pelvis (Fig. 5). CLINICAL COURSE Six months later, the patient returned and was admitted to the hospital with intractable nausea and vomiting and generalized abdominal pain
The patient underwent computed tomography (CT) scan of the abdomen and pelvis which confirmed a lobulated calcified mass within the umbilicus, measuring 2.7 cm × 3 cm with no additional cystic or solid component (Figs. 1A-D).There was no intra-abdominal lymphadenopathy or aggressive appearing boney lesions Abdominal and pelvic computed tomography (CT) revealed a mummified fetus, depicting in great detail the fetal anatomy [Figure 2]. The calcified mass was in close contact with abdominal organs, showing adherences to the bladder wall. It was 19 × 17 × 10 cm in size and femur length was 6.7 cm, with an estimated gestational age of 34-35 weeks Calcified liver and peritoneal metastases from ovarian carcinoma are seen in the liver and along peritoneal surfaces (white arrows). · Usually fine sand-like calcification frequently difficult to see on plain radiographs. - Choriocarcinoma mostly of placental origin occurs in prepubertal girls. Highly malignant
The patterns of gastric involvement include polypoidal mass, diffuse or focal infiltration, ulcerative lesion, or mucosal nodularity . The infiltrating form is the most common (Figure 20) and may be difficult to differentiate from scirrhous carcinoma. CT demonstrates gastric wall thickening with a smoothly lobulated outer border A 65-year-old white female was admitted for evaluation of an abdominal mass associated with recurrent episodes of right lower quadrant pain. The past history included an appendicectomy and a total abdominal hysterectomy with bilateral salpingo-oophorectomy for post-menopausal bleeding three years prior to this admission Gastric Cancer: Introduction The geographic incidence of gastric cancer has changed dramatically over the last few decades. Prior to 1950, it was the most common cause of cancer death in men, and the third leading cause of cancer death in women in the U.S. Mortality from gastric cancer in the United States has declined, perhaps due to dietary. A coronal reformatted (above) and axial CT scan (below) of the upper abdomen show bilateral calcifications (red and white circles) in both adrenal glands. The adrenal glands are not enlarged. These calcifications were found incidentally and are most likely due to previous adrenal hemorrhage. The liver (L), spleen (S) and kidneys (K) are labeled Retroperitoneal masses radiology. Well-differentiated liposarcoma in a 58-year-old woman is shown as a large homogeneous fat-containing mass with thick septa (arrows) that show soft tissue attenuation. Myelolipoma in a 44-year-old woman. Axial CT image shows a large mass containing fat (arrow) and soft-tissue (arrowhead) components in the right.
- Abdominal wall endometriosis - defined as endometrial tissue that is superficial to the peritoneum & is a common site of extrapelvic endometriosis that usually develops in a surgical abdominal scar like after caesarean section with typical presentation of female patient with cyclical pain from a solid mass in scar tissue with iso- to mildly. Plain abdominal radiographs are commonly ordered in inpatient and outpatient settings for patients with a variety of abdominal complaints. In addition to the gastrointestinal system, a variety of critical and/or incidental findings in the genitourinary, hepatic, biliary, and vascular systems can all be identified on abdominal radiographs An intravenous urography was performed, which showed normal nephrograms and pyelograms (Fig 1b). Whilst in the department an abdominal CT without further contrast was performed, which showed a 10cm x 10cm cyst with a calcified wall lying anteriorly in the spleen. There was no other intra-abdominal pathology (Fig 3)
Eight cases were diagnosed incidentally. Two had no abdominal pain but were diagnosed based on palpating an abdominal mass during a routine physical examination . The other six patients were diagnosed with a calcified mass seen on plain X-rays obtained for an unrelated reason [2, 3, 6, 10, 12]. The AO was the right ovary in 17 cases, the left. The CT features suggestive of abdominal TB include irregular soft-tissue densities in the omentum, low-attenuating masses surrounded by thick solid rims, low-attenuating necrotic nodes, disorganized appearance of soft-tissue densities, high-attenuating ascitic fluid and bowel loops forming poorly defined masses, and a multiloculated appearance. In an attempt to further characterize the calcified lesion, which was mistaken for a retroperitoneal mass during surgery, an abdominal and pelvic computed tomography (CT) examination was requested and performed two days after surgery, in a 4-row multidetector CT equipment (BrightSpeed, GE Healthcare, US) using a non-enhanced acquisition protocol (slice thickness: 2.5 mm, pitch: 1.5. Fig. 1 Radiological and pathological findings of immature gastric teratoma in a 3-month-old boy. A.

We report a case of ossifying renal tumor of infancy, which presented as a palpable abdominal mass in an otherwise asymptomatic 10-month-old girl. The tumor was partially calcified and occupied the renal pelvis, causing severe hydronephrosis. The differential diagnosis for a patient this age included Wilms tumor, extra-adrenal neuroblastoma, infection, calculus, calcified hematoma and. Calcification and the Kidneys. Calcification is the abnormal accumulation of calcium salts in body tissue. This abnormal accumulation of calcium in the kidney is referred to as nephrocalcinosis. Sharp lower abdominal pain and calcified abdominal mass Sihler, Kristen MD ; Mazza, Michael MD ; Napolitano, Lena M. MD ; Feliciano, David V. Journal of Trauma and Acute Care Surgery: June 2015 - Volume 78 - Issue 6 - p 1231-123 of the abdomen and pelvis shows a cystic mass with a rim-like calcification (red arrows) containing fat density lower than that of the surrounding soft tissue. There is a calcification within the mass (blue arrow) which represents a tooth. This is a diagnostic appearance for a dermoid cyst of the ovary Calcification (Cartilaginous process)- Unorganized calcified matrix which is comma-shaped, punctate, annular or popcorn-like. Eg. Enchondroma, Chondrosarcoma, Chondromyxoid fibroma.

Calcified Splenic Cyst. Consultant: Volume 50 - Issue 2 - February 2010. A 38-year-old man found lying on the floor in his home was hospitalized because of alcohol intoxication. A chest radiograph showed a large calcified lesion in the left upper abdomen ( A ). A CT scan with intravenous contrast revealed a large, well-defined, cystic mass with. eferred to our hospital for evaluation of low back pain for 4 years and abdominal pain for 1 month. Diagnoses: Computed tomography (CT) of the abdomen showed a hypodense mass in the pancreatic head and neck with abundant calcifications, a hypodense lesion in the liver without calcification, peripancreatic lymphadenopathy, calcifications in some lymph nodes. CT-guided fine needle aspiration. A 52-year-old woman underwent an abdominal MRI for an incidentally found cystic mass within the pancreatic tail (Figure 1A-C). She had no inciting symptoms related to the pancreatic lesion, and medical and surgical history were noncontributory. All laboratory values were within normal range. Key Imaging Finding. Cystic pancreatic mass We present the case of an 83-year-old man who had painful swelling of right knee for 6 months. Radiographs showed a large intra-articular soft-tissue mass with small calcifications, whereas MRI detected a multilobulated intra-articular tumor with bone erosions at the distal femur. Histopathology of Mucinous cystic neoplasms (MCNs) of the pancreas are uncommon, and their diagnosis, treatment, and prognosis have yet to be uniformly determined in full. Differentiation of cystic lesions of the pancreas is difficult, as they can be benign (serous cystadenomas), inflammatory (pseudocyst of the pancreas), or malignant
