Traumatic retroperitoneal hematoma illustrated on Tc-99m methylene diphosphonate bone scintigraphy in a patient presenting with a fall.

Retroperitoneal haematoma is rarely described in the context of bone scintigraphy, as it is usually an incidental discovery on bone scan carried out for another purpose. We report a case of a right retroperitoneal haematoma detected on Tc-99m-methylene diphosphonate bone scintigraphy taken in an elderly patient presenting with a mechanical fall and a right acetabular fracture.
