OBJECTIVE: To report preliminary results of aneurysm neck remodeling in the management of wide-necked renal artery aneurysms. MATERIALS AND METHODS: Five patients (three women and two men between 49-72 years; mean age, 62 years) with wide-necked renal artery aneurysms measuring from 10 to 25 mm in diameter were submitted to balloon-assisted coil embolization along a three-year period. The micro-balloon was placed along the aneurysm neck and temporarily inflated for introduction of detachable microcoils into the aneurysmal sac. RESULTS: Balloon positioning and microcoil embolization were successfully completed in all of the cases with achievement of complete aneurysm occlusion without coil protrusion or parent vessel obstruction. CONCLUSION: The present preliminary experiment indicates that the "aneurysm neck remodeling" is technically feasible and effective in the management of complex renal artery aneurysms without sacrificing any arterial branch.

Pseudoaneurysms are considered rare conditions. The authors describe the rarity of the occurrence of a pseudoaneurysm secondary to traumatic injury of the common carotid artery in association with a femoral osteochondroma. The importance of imaging methods, particularly computed tomography angiography, in the diagnosis of vascular pathologies are emphasized, and the literature is reviewed.

In the literature, there is no evidence of relationship between primary bone lymphoma and osteochondroma or of coexistence of both of them in a single bone. The present report describes an uncommon case of primary bone lymphoma occurring simultaneously with osteochondroma in the proximal third of the tibia. In the present case, magnetic resonance imaging signs simulated the presence of sarcomatous degeneration.
