Inflammatory myofibroblastic tumors are lesions that most often affect young adults and children. These tumors have been found in numerous extrapulmonary sites but rarely in the stomach. It is unknown whether this process is reactive or neoplastic. They are infiltrative lesions and often extend through the gastric wall, sometimes reaching adjacent organs including the esophagus, duodenum, peritoneal cavity, spleen. pancreas, and liver. These features mimic malignancy on endoscopy and radiology. We report the ultrasound, color Doppler ultrasound, and helical computed tomographic findings of a gastric inflammatory myofibroblastic tumor with peritoneal dissemination in a young adult. To our knowledge, this is the first report of color Doppler ultrasound and helical computed tomographic findings of this rare disease entity.
Renal cell carcinoma (RCC) is the most common solid renal neoplasm. Clear cell (conventional) carcinoma is the most common pathologic subtype of RCC. Usually RCC is a hypervascular, solid, solitary mass with contour bulging. However, RCC can manifest different features according to the pathologic tumor subtypes. Preoperative diagnosis of cyst-associated RCC is very difficult, especially in cases of RCC originating in a cyst. Multiple or bilateral presentation of RCC occurs in fewer than 5% of cases. In addition, RCCs may demonstrate unusual findings such as infiltrative growth mimicking transitional cell carcinoma, fatty component mimicking angiomyolipoma, severe perinephric infiltration, and extensive calcifications mimicking inflammation or other tumor. RCCs can be associated with hereditary diseases such as von Hippel-Lindau disease. Familiarity with these radiologic features of unusual RCCs can help ensure correct diagnosis and proper management.
transvaginal ultrasound to observe the sonographic features associated with the disease. Patients with histologically confirmed pelvic tuberculosis were scanned on a monthly basis to observe sonographic changes during therapy. Results: The most common sonographic features were ascites (68%), pseudocyst (57%), matted bowel loops (39%), bilateral complex adnexal masses (32%) and normal ovaries (79%). Peritoneal thickening was seen in 14% of cases appearing as a 'pelvic blanket' walling off pelvic organs from the abdominal cavity. Nine patients were followed up during therapy with earliest normal sonographic findings observed during the fourth month of anti-Koch's therapy. One patient had a progressive hydrometra relieved by cervical dilatation after it was detected by ultrasound. Conclusion: The diagnosis of abdominopelvic tuberculosis cannot be made with certainty from a sonogram, but it may be helpful. The presence of ascites, pseudocysts, peritoneal thickening, serosal stipplings and complex adnexal masses in the presence of visibly normal ovaries should lead one to consider the possibility of abdominopelvic tuberculosis. The response of the disease to therapy may also be monitored by serial ultrasound. P43.15 Benign ovarian tumors with solid and cystic components that mimic malignancy
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
