Biloma is defined as any collection of bile outside the biliary tree, usually resulting from surgery complications and abdominal trauma. Spontaneous occurrence of bilomas is rare, occasionally associated with choledocolithiasis. The present report describes a case of spontaneous biloma, whose diagnosis was radiologically confirmed. At laparotomy, the presence of a retroperitoneal biloma was observed. Intraoperative cholangiography has not demonstrated the presence of fistula. After drainage, the patient progressed well and was discharged.
Keywords: Biloma; Choledocolithiasis; Retroperitoneum.
