Renal artery aneurysms

Introduction: Technical improvement of computed tomography scanning facilit ates the diagnosis and treatment planning of renal artery aneurysms. Case R eport: A 77-year-old male patient complained about acute flank pain and gro ss hematuria. During preoperative work-up, a helical CT study was performed . In the arterial phase of contrast enhancement, a lesion measuring 2.5 cm with intensive contrast filling is detected in the left kidney which permit s the diagnosis of a renal artery aneurysm. Treatment consisted of supersel ective coil embolisation. The aneurysm was completely occluded at angiograp hic and computed tomographic control. The patient was followed up 12 months after embolisation and CT demonstrated contrast enhancement in the locatio n of the aneurysmal sac. Additional angiography was obtained and ruled out reperfusion of the aneurysmal cavity. The hypervascularized residuum remain ed unchanged at follow-up 22 months after embolisation. Conclusions: The pr esented case illustrates the diagnostic advantages of spiral computed tomog raphy and the percutaneous transcatheter treatment for a renal artery aneur ysm.
