Spontaneous biloma due to an intrahepatic cholangiocarcinoma: An extremely rare case report with long term survival and literature review

Spontaneous Biloma With a Hepatic Mass

We report a case of an 86-year-old Hispanic male who presented with generalized itching and jaundice. Computed tomography (CT) imaging revealed a hepatic mass and an extensive spontaneous biloma, a condition rarely associated with malignancy. Subsequent biopsy of the mass confirmed moderately differentiated adenocarcinoma of the pancreaticobiliary tract. The patient underwent successful percutaneous drainage of the biloma and was discharged with a plan for further outpatient management. This case study highlights a rare manifestation of spontaneous biloma related to malignancy, broadening the clinical understanding of its association with malignancy, diagnosis, and management.

Case Report: Biloma gastrostomy after failed sonogram-guided percutaneous aspiration, pigtail catheter insertion and surgical drainage

Bilomas are rare abnormal extrabiliary accumulation of bile.  This can be either intrahepatic or extrahepatic following traumatic or spontaneous rupture of the biliary tree. The commonest causes of biloma are surgery, percutaneous transhepatic cholangiography, percutaneous transhepatic biliary drainage, transcatheter arterial embolization and abdominal trauma. We report here a 15 year old patient whom we followed for over 10 years. His chief complaints were right hypochondriac pain, loss of appetite and vomiting. Initial clinical presentation, sonographic as well as laboratory findings suggested a liver abscess, which was drained, but the definitive diagnosis of biloma was entertained after sonographically guided percutaneous aspirations and percutaneous transhepatic cholangiography 7 years later. We also discuss the role of imaging and surgical challenges encountered that culminated into bilomo-gastrostomy. The patient is now enjoying a peaceful life.

Intrahepatic subcapsular biloma after endoscopic retrograde cholangiopancreatography treated by endoscopic biliary drainage

Several major complications from endoscopic retrograde cholangiopancreatography (ERCP), including pancreatitis, cholangitis, and hemorrhage have been discussed in detail; however, a few uncommon but severe complications have been reported. We encountered an unusual case of post-ERCP intrahepatic subcapsular biloma. An 89-year-old woman with a 25-mm mass located at the hepatic hilum, suggestive of cholangiocarcinoma, underwent ERCP which demonstrated complete stricture of the common hepatic duct. Subsequently, two plastic stents were placed from the common bile duct to the right and left intrahepatic branches. On day 3, serum inflammatory markers were elevated and computed tomography revealed a large subcapsular fusiform fluid collection in the right liver, consistent with biloma. On day 6, the biloma ruptured and 500 ml of biliary ascites were removed. On day 8, endoscopic nasobiliary drainage via the right intrahepatic branch was performed because of recurrence of biliary ascites. After the procedure, 150 ml of bile was collected through the drain every day and no ascites recurred. We believe that minor injury to the right intrahepatic bile duct due to guidewire manipulation caused the biloma. Biloma may become apparent several days after ERCP, and endoscopic biliary drainage placement adjacent to the bile duct rupture site can stop bile leakage.
