1/44. Heterotopic gastric mucosa in the gallbladder: sonographic and CT findings.We present computed tomographic (CT) and sonographic findings of heterotopic gastric mucosa incidentally found in a 63-year-old male. CT showed a slightly high density area in the gallbladder, which was intermediately enhanced early after bolus injection of contrast medium. ultrasonography showed an echogenic sessile polyp. Histologically, the tumor consisted of gastric fundic glands containing parietal cells and chief cells.- - - - - - - - - - ranking = 1keywords = gallbladder (Clic here for more details about this article) |
2/44. Heterotopic pancreas--an unusual cause of cholecystitis.A 47-year-old woman presented with signs and symptoms of acute cholecystitis. A routine cholecystectomy was performed. No gallstones were present. On histological examination of the gallbladder, a nodule impinging on the lumen was present in the region of the cystic duct. This nodule was composed of mature, uninflamed exocrine and endocrine pancreatic tissue. In the absence of gallstones, the heterotopic pancreas was the cause of obstruction, with subsequent cholecystitis.- - - - - - - - - - ranking = 0.2keywords = gallbladder (Clic here for more details about this article) |
3/44. Heterotopic gastric mucosa in the gallbladder.We report on a case of heterotopic gastric mucosa in the body of the gallbladder. A 39-year-old man, who was asymptomatic, visited our hospital because of a polypoid lesion in the gallbladder, discovered during a routine health screening. ultrasonography (US) revealed a broad-based polypoid lesion 1.7 cm in diameter in the body of the gallbladder, which was free of gallstones. The gallbladder mass was faintly enhanced by helical computed tomography. Laparoscopic cholecystectomy was performed because of the possibility of malignancy. The specimen revealed a 1.7 x 1.3 cm polypoid lesion with deep delle in the body, with no gallstones in the gallbladder. Intraoperative frozen examination yielded a diagnosis of hyperplastic polyp of the gallbladder. Histologically, the polypoid lesion consisted of gastric fundic glands located in the whole wall of the gallbladder. The surrounding mucosa consisted of almost normal epithelium without any metaplastic changes. Postoperative technetium 99m-pertechnetate scintigraphy demonstrated no evidence of gastric heterotopia elsewhere in the body. We also review 18 other reports of heterotopic gastric mucosa in the gallbladder in the Japanese medical literature.- - - - - - - - - - ranking = 2.4keywords = gallbladder (Clic here for more details about this article) |
4/44. Ectopic liver (choristoma) associated with the gallbladder encountered during laparoscopic cholecystectomy: a case report.Ectopic liver has been but rarely described usually in the vicinity of liver such as on the gallbladder, hepatic ligaments, diaphragm, thoracic cavity, adrenal glands, pancreas, omentum, spleen, esophagus and umbilical cord. A simple classification for anomalous liver tissues found on the wall of gallbladder is 1. Accessory liver lobe 2. Ectopic nodule 3. Aberrant microscopic tissue. Ectopic nodules of liver tissue attached to the gallbladder are completely detached from the liver and has been described by various names such as accessory lobe, ectopic liver, accessory liver and heterotopic liver but the specific pathological term for this entity is choristoma introduced by Albert in 1904 meaning displacement. Several possible mechanisms may explain ectopic liver at various sites such as the development of an accessory lobe of the liver with atrophy or regression of the original connection to the main liver or migration of pars hepatica to the rudiment of various organs. In this paper we present a case of ectopic liver or choristoma attached to the gallbladder encountered during an elective laparoscopic cholecystectomy which was successfully removed with the gallbladder.- - - - - - - - - - ranking = 1.8keywords = gallbladder (Clic here for more details about this article) |
5/44. Ectopic liver tissue attached to the gallbladder.A 55-year old woman underwent cholecystectomy for cholelithiasis. The removed gallbladder showed a serosal encapsulated nodule, measuring 14 x 6 mm, that histologically was an ectopic functioning liver. This nodule had no connection with the main liver. Accessory liver tissue is nearly always an incidental finding in the course of operations and postmortem examinations. It arises in the neighbourhood of the gallbladder from residual liver cells in the caudal part of the embryonic liver; it may also be found in some other organs and structures in close proximity to the liver during fetal life.- - - - - - - - - - ranking = 1.2keywords = gallbladder (Clic here for more details about this article) |
6/44. Heterotopic gastric mucosa involving the gallbladder and biliary tree.A case of heterotopic gastric mucosa in the common bile duct, cystic duct and gallbladder is reported in a 3-year-old girl with abdominal pain and jaundice. Abdominal US and CT showed dilatation of the biliary tree and a well-defined mass in the common bile duct that narrowed its lumen. The gallbladder was contracted in both examinations. The common bile duct and the gallbladder were resected and a choledochojejunostomy was performed. Although gastric heterotopy has been described throughout the entire length of the gastrointestinal tract, it is a very uncommon finding in the gallbladder and extremely rare in the biliary tree. A firm diagnosis of gastric heterotopia is based on the presence of fundal mucosa replete with parietal and chief cells. To our knowledge, this is the fifth reported case of heterotopic gastric tissue within the common bile duct, and the first to describe the US and CT findings. A relevant literature review and brief outline of the histological and radiological features are included in the discussion.- - - - - - - - - - ranking = 1.6keywords = gallbladder (Clic here for more details about this article) |
7/44. cholecystitis associated with heterotopic pancreas.Heterotopic pancreas is a rare developmental anomaly usually reported as an incidental finding. We describe a 1 cm diameter gallbladder heterotopic pancreas identified at pathological study. The patient, a 23-year-old woman, was suffering from cholecystitis. She underwent cholecystectomy with an uneventful course.- - - - - - - - - - ranking = 0.2keywords = gallbladder (Clic here for more details about this article) |
8/44. Ectopic thyroid in the gallbladder: report of a case.Ectopic thyroid is a rare developmental anomaly. We describe an unusual case of ectopic thyroid tissue found in the gallbladder wall of a 68-year-old man who underwent cholecystectomy for acute cholecystitis. Pathological findings were compatible with ectopic thyroid tissue in the gallbladder wall. This very rare pathology is discussed with a review of the relevant literature.- - - - - - - - - - ranking = 1.2keywords = gallbladder (Clic here for more details about this article) |
9/44. Heterotopic gastric mucosa in a duplicate gallbladder.A 7-year-old girl presented with recurrent acute pancreatitis. Detailed investigations, including endoscopic retrograde cholangiography, suggested a poorly defined biliary tract abnormality. At laparotomy, this was discovered to be a duplicate gallbladder each with a separate cystic duct but contained within a single serosal envelope. Both gallbladders were removed, and histologic examination found the inferior organ to be lined by heterotopic fundic-type gastric mucosa. Despite the absence of any remaining structural biliary abnormality and no evidence of residual ectopic gastric mucosa, the patient experienced a few further episodes of self-limiting mild acute pancreatitis during the following 3 years. The presence of heterotopic gastric mucosa in a duplicate gallbladder has not been described previously.- - - - - - - - - - ranking = 1.4keywords = gallbladder (Clic here for more details about this article) |
10/44. morphine-augmented cholescintigraphy with a false-negative result and an apparent ectopic gallbladder.morphine-augmented cholescintigraphy has been shown to be a highly sensitive and specific means of evaluating acute cholecystitis. False-negative results do occur infrequently, however, and such a case is reported. In addition, this case initially demonstrated an apparent ectopic gallbladder, and thus anomalies in location of the gallbladder will be discussed.- - - - - - - - - - ranking = 1.2keywords = gallbladder (Clic here for more details about this article) |
