Traumatic bile duct neuroma presenting with acute cholangitis: A case report and review of literature

Traumatic neuroma of the biliary tree has been previously reported as isolated case reports. In literature, these typically present following prior liver transplant or cholecystectomy, wherein the bile ducts have been disrupted in some form. Here we report the case of a 41-year old male who initially presented with acute cholangitis ten years after an open cholecystectomy complicated by a bile leak. Endoscopic retrograde cholangiography revealed a stricture within the mid distal common hepatic duct. The patient temporarily resolved his initial episode with stent placement, and he was eventually taken to the operating room for bile duct resection and hepaticojejunostomy given a persistent stricture and concern for underlying malignancy. Final pathology demonstrated a traumatic bile duct neuroma. This unusual entity should be considered in patients with benign appearing strictures presenting years after surgery, and awareness may aid in preoperative counseling as well.
