Abstract
A biloma is an encapsulated collection of bile located in the abdomen. It usually occurs spontaneously or can be secondary to traumatic injury (hepatobiliary surgery) and in rare condition it can occur as complication of cholecystitis and cholangiocarcinoma. The diagnosis can be suggested on the basis of patient’s medical history, clinical symptoms and imaging findings but final definitive diagnosis can only be made by aspiration of the content and biochemical analysis. We here report a case of 62 years male patient admitted with acute abdominal pain in the right hypochondrium caused by a spontaneous biloma. We discuss the role of the various diagnostic imaging techniques, particularly which of ultrasound and CT. The biloma was identified on computed tomography in this case.
Highlights
Biloma is defined as a bile collection, either encapsulated or not, outside the biliary tree, with intra- or extrahepatic location, generally of iatrogenic nature or resulting from abdominal trauma.[1,2]
Computed tomography (CT) confirmed the distended gallbladder with perforation in fundus and fistulous communication with subcapsular collection in liver and the patient was submitted to laparotomy, which confirmed the tomographic report
Gall bladder perforation is seen in 2-10% of acute cholecystitis cases.[7]
Summary
Biloma is defined as a bile collection, either encapsulated or not, outside the biliary tree, with intra- or extrahepatic location, generally of iatrogenic nature or resulting from abdominal trauma.[1,2] The word “biloma” was first utilized by Gould & Patel[3] in 1979, but there are descriptions of such an entity since the century XIX.[4].
