[Intratumoral endometriosis in renal angiomyolipomas associated to medium vessel necrotizing vasculitis in a patient with Wünderlich syndrome. A rare finding].

Spontaneous perirenal hematoma or Wünderlich syndrome is a rare entity that requires urgent attention. The most frequent causes are renal neoplasms, mainly renal angiomyolipoma, and vascular diseases (vasculitis). We present a case of a woman with a history of renal angiomyolipomas associated with tuberous sclerosis complex, who developed Wünderlich's syndrome associated with medial vessel vasculitis as well as an uncommon instance of intratumoral endometriosis.
