BACKGROUND Neuroendocrine carcinoma is rare with a proportion of less than 2% in gallbladder malignancies, cases of gallbladder neuroendocrine cell carcinoma coexisting with adenocarcinoma are exceptionally rare, and the prognosis is dismal. METHODS Herein, we presented an unusual case of poorly differentiated gallbladder neuroendocrine cell carcinoma coexisting with poorly differentiated ade...

operation11. Until surgeons are more alert to a preoperative or peroperative diagnosis and until the limits of radical surgery are defined the further treatment of gallbladder carcinoma invading perimuscular connective tissue but not serosa must remain an open question. Gallbladder carcinoma first diagnosed by microscopic examination of gallbladders removed for presumed benign disease. (1990) O...

A 7-year-old girl was diagnosed with viral enteritis and was admitted to our hospital. Sudden right upper quadrant tenderness appeared 2 days after admission. Ultrasonography revealed a large thick-walled cystic gallbladder and an inflammation-induced hyperechoic cystic duct. The long axis of the gallbladder was in a horizontal rather than a vertical alignment. Computed tomography demonstrated ...

Background: Gallstone ileus, which is called Type Vb Mirizzi Syndrome, a rare case of mechanical intestinal obstruction observed in older patients with history cholelithiasis or cholecystitis. Diagnostic Imaging plays an important role the management suspected gallstone ileus. X-Ray and Abdominal Computed Tomography (CT) are preferred modality. Case presentation: The patient was diagnosed ileus...

Squamous cell carcinoma of the gallbladder is rare and constitutes only 0.5-3% of all malignancies of this organ. Most of the reported cases have had a component of adenocarcinoma. We report a 70-year-old man who presented with acute onset right upper quadrant pain. He operated on based on a presumptive diagnosis of acute cholecystitis according to clinical and ultrasonographic findings. Histop...

CONTEXT Heterotopic pancreas of the gallbladder is an extremely rare entity, especially when pancreatic tissue appears histologically with an exclusively exocrine structure. CASE REPORT We report the case of a 35-year-old man who presented with symptoms of acalculous gallbladder disease with high levels of amylasuria. Immunohistochemical analysis of the surgical specimen of the cholecystectom...

Adenomyomatosis of the gallbladder is a benign and degenerative condition of the gallbladder, characterized by proliferation of the mucosa of the gallbladder wall, forming invaginations and diverticula, penetrating a thickened muscular layer: the so-called Rokitansky-Aschoff sinuses (RAS). Most of the patients with adenomyomatosis remain asymptomatic. Hence adenomyomatosis is usually an inciden...

We report a case of intramural gallbladder hematoma mimicking gallbladder neoplasm in a 33-year-old male; bleeding was confined to the gallbladder wall without rupture into the lumen. The patient presented with sudden onset of right upper quadrant pain, with no history of abdominal trauma. The abdomen was soft, with mild tenderness over the right upper quadrant, and a positive Murphy's sign. Ab...

A case of the rare congenital anomaly ectopic gallbladder is presented. A 16-year-old girl suffered attacks of epigastric pain unrelated to eating. On abdominal ultrasonography, the gallbladder could not be found in its usual position. Endoscopic retrograde cholangiography demonstrated the gallbladder on the left side of the common duct and the cystic duct arising from the right hepatic duct. L...

Sonographic images of the gallbladder enable satisfactory approximation of gallbladder volume using the sum-of-cylinders method. The sum-of-cylinder measurements, however, are moderately cumbersome and time consuming to perform. In this investigation, in vitro and in vivo testing was done to determine that a simple ellipsoid method applied to sonographic gallbladder images yields reasonable vol...
