Delayed Radiographic Manifestation of Renal Pseudoaneurysms After Blunt Trauma

Pseudoaneurysms may cause recurrent hematuria after blunt renal trauma. We report on an 18-year-old patient with radiographic manifestation of pseudoaneurysm 41 days after blunt renal trauma. Initial and follow-up imaging for recurrent hematuria, including angiography, was without signs of pseudoaneurysm or active bleeding. This case illustrates that recurrent gross hematuria as a typical symptom of pseudoaneurysm may be present initially in the absence of radiographic signs. Repeat angiography should be taken into consideration if recurrent bleeding persists.
