title: Hypertension due to an aneurysm of the left renal artery in a patient with neurofibromatosis.
abstract: Arterial lesions in patients with neurofibromatosis are rarely described and in most cases are stenotic. The aneurysmal changes reported in the literature are usually characterized by multiple microaneurysms due to the dysplastic lesions of the artery. We report a case of a single aneurysm of the inferior hilar branch of the left renal artery of a young female with neurofibromatosis. The patient showed hypoperfusion of the renal pole fed by this branch and was hypertensive. The aneurysm had a diameter of 4 cm and showed the histological findings typical of dysplastic lesions of neurofibromatosis. The hypertension and the renal pole hypoperfusion recovered after surgical excision of the aneurysm and end-to-end anastomosis of the hilar branch stumps.
