We compared the ultrasound (US) findings of gallbladder (GB) perforation with computed tomography (CT) in 13 patients with GB perforation confirmed at surgery. The common findings of GB perforation were pericholecystic fluid collection and layering of GB wall on US, pericholecystic fluid collection, streaky omentum or mesentery, and GB wall defect on CT. Pericholecystic fluid collection, layering of GB wall, and cholelithiasis were similarly detected on US or CT. GB wall defect and/or bulging of the GB wall suggested a site of perforation was revealed in five patients (38.5%) on US and nine (69.2%) on CT. CT further disclosed the findings of streaky omentum or mesentery (84.6%). CT was superior to US for diagnosis of GB perforation.

We report three cases of intraperitoneal seeding from hepatoma. Manifestation of intraperitoneal seeding from hepatoma were intraperitoneal masses (N = 2) and peritoneal thickening (N = 1). Main vascular feeder to intraperitoneal masses was omental branches of the gastroduodenal artery and/or the superior mesenteric artery.

Lymphomatoid granulomatosis usually presents as a primary lung affliction with secondary metastatic spread to the central nervous system(CNS), and its initial manifestation purely as a CNS disease is rare. A 57-year-old man with histologically proven lymphomatoid granulomatosis of the brain as the sole manifestation of the disease is presented.
