Osseous hemangiopericytoma is rare. We present a case of a 30-year-old woman with low-back pain with radiation to the left buttock for 1 month. Magnetic resonance imaging (MRI) showed a tumor mass with areas of serpentine signal void pattern in the sacrum suggestive of a vascular tumor. Neither calcifications nor layered blood serum were noted. Histological diagnosis was compatible with osseous hemangiopericytoma.

Surgical complication after biliary tract injury are serious complications of Hepatobiliary surgery. Theincidence of iatrogenic bile duct injuries has increased significantly since the number of cholecystectomy operationshave increased, laparoscopic cholecystectomy became the "gold standard", mini-cholecystectomy established for thetreatment of cholelithiasis. Intraoperative hemorrhage can be life-threatening or may lead the death. The common usesof laparoscopic cholecystectomy and mini-cholecystectomy have made the young surgeons less familiar with opencholecystectomy procedure and the approaches to manage the biliary tract injuries. Uncommonly the patient had toundergo hepatic transplantation secondary to biliary tract surgery with several vessel injuries or biliary cirrhosis.Postoperative bile leakage can be managed by effective drainage as soon as possible. These complications uncommonwith the expert surgeons, but common with comparatively inexperienced surgeons. There is no substitute of experienceand caution in biliary surgery for optimization technique.
