Abstract

Renal artery pseudo-aneurysm following trauma is rare in children. Bleeding pseudo-aneurysm requires high index of suspicion for early diagnosis and proper management. This report describes a 10-year-old boy who presented with delayed bleeding from a renal artery pseudo-aneurysm following a motor vehicle accident. Contrast enhanced computed tomography scan showed a bleeding pseudo-aneurysm in the upper pole lobar artery of the left kidney. Angio-embolization of the pseudo-aneurysm was successfully done using pushable coil. Post-embolization recovery was marked by temporary minimal abdominal pain and hematuria that resolved without any residual renal dysfunction. Awareness of this rare condition is crucial for early detection and successful management.
