[Spontaneous retroperitoneal hematoma: a rare cause of hemorrhagic shock].
A spontaneous retroperitoneal haematoma is an uncommon cause of haemorrhagic shock. We report a case of spontaneous rupture of a renal angiomyolipoma resulting in haemorrhagic shock in a 52-year-old woman. The renal tumor was recognized by sonography and diagnosed by CT-scan. Renal angiography was performed, but embolization was not successful. During the surgical procedure, nephrectomy was required because of persistent bleeding, related to disseminated intravascular coagulation. Outcome was uneventful. Diagnosis and treatment of renal angiomyolipoma are discussed. The Lenk's triad, consisting of acute lumbar pain, symptoms of internal bleeding and lumbar tumefaction, is the usual clinical picture of retroperitoneal haemorrhage. The kidney is the most frequent cause and renal angiomyolipoma is the most frequent benign tumor. Renal angiomyolipoma is either isolated or associated with tuberous sclerosis in up to 20 per cent of patients. Diagnosis is suggested by sonography and confirmed by CT-scan. Renal angiography, performed in haemodynamically stable patients, shows the origin of bleeding and allows embolization. Considering the frequent bilaterality of angiomyolipoma, surgery should be as conservative as possible in order to preserve renal function.
