Spontaneous biloma: a case report

A biloma is an encapsulated collection of bile located in the abdomen. It occurs spontaneously or secondary to traumatic or iatrogenic injury to the biliary system. The patient's medical history, symptoms and diagnostic imaging findings suggest the diagnosis, but a definitive diagnosis is provided by drainage and biochemical analysis of the fluid. We report a case of a patient admitted with acute abdominal pain in the right hypochondrium caused by a spontaneous biloma. This is a rare condition, and the reason for the onset was not identified. We discuss the role of the various diagnostic imaging techniques, particularly that of ultrasound.
