[Clinically asymptomatic congenital macrofistular AV-aneurysm of the kidney]

Congenital arteriovenous aneurysms of the kidney are rare. The case of a now 65-year-old female patient is explained, in whom in 1971 during a renovasography on account of renal cyst at the left side of congenital arteriovenous aneurysm of the right kidney was established. Today - almost 10 years after the diagnosis and near her eight decennium of life - the patient is clinically symptom-free as to the untreated arteriovenous aneurysm of the right kidney. The observation shows that in arteriovenous aneurysms of the kidney cases with clinical relevancy and clinically asymptomatic cases must be differed.
