Various tumors or vascular lesions Could potentially be seen as incidental findings on dynamic renal scintigraphy. We report on a case in which Tc99m-DTPA dynamic renal scintigraphy unexpectedly showed a photopenic lesion in the liver, which was later confirmed by computed tomography as hepatic hematoma secondary to traumatic injury. Interestingly, this lesion was missed on previous ultrasonography performed before scintigraphy. In this particular patient, dynamic renal scintigraphy made it possible for the clinicians to reevaluate the liver with computed tomography after trauma. It can be concluded that dynamic renal scintigraphy is a reliable functional imaging modality to evaluate patients with a history of abdominal trauma, and it may have the potential of displaying incidental findings secondary to traumatic injury that may be missed initially and thus help in patient management.
