[Hemangioma of the kidney--diagnostic and therapeutic problems].

Hemangioma of the kidney as one of the possible causes of "essential hematuria" is discussed with special regard to its diagnostic features in the various modern radiological examinations. Still most important is angiography. Typical findings are demonstrated in a case with complete replacement of the parapelvic fat by a large cavernous hemangioma. The various therapeutic possibilities--conservative treatment, embolisation, partial or complete nephrectomy - are discussed.
