[Renovascular hypertension in neurofibromatosis von Recklinghausen (author's transl)].

The course of the illness in a six-year-old boy is reported. His recurrent headaches led to the detection of arterial hypertension (170/135 mmHg). Clinical and histological examination revealed neurofibromatosis von Recklinghausen. A bilateral paraumbilical murmur hinted at a renovascular form. Arteriography showed an aneurysm of the right renal artery and multiple bilateral intrarenal stenoses and aneurysmatic dilatations. Under conservative treatment with Propranolol and Dihydralazine blood pressure remained almost normal over two years. 38 paediatric cases of renovascular hypertension in childhood reported in the literature are analyzed with regard to clinical manifestation, morphology and localisation of the renovascular lesions.
