Renal artery pseudoaneurysm secondary to blunt trauma nine years earlier: case report and review of the literature.

This report describes a 59-year-old male with a renal artery pseudoaneurysm secondary to blunt trauma from a snowmobile accident. The patient presented with haematuria and flank pain, 9 years after the injury. This is the second longest interval between initial trauma and aneurysm rupture in published cases. The diagnosis was delayed because the doctors were unaware of the initial trauma. In cases of haematuria, flank pain and computed tomography showing a tumour in the renal hilum, the patient should be questioned about previous abdominal trauma, as pseudoaneurysms can rupture many years after the causative injury.
