[Macroscopic hematuria and artery aneurysm].

Intraparenchymal renal artery aneurysms in the renal artery are rare in the general population. Prevalence range from 0.01 to 1.0%, women are more often affected and the predominant location is the right kidney. Several complication have been described, hypertension, dissection, thrombosis, renal infarction and spontaneous rupture. Here, we report a case of an aneurysm of a branch of the left renal artery diagnosed after gross haematuria. Selective intra-arterial embolization leads to the thrombosis of the aneurysm and the disappearance of haematuria.
