title: [Etiology and diagnosis of severe retroperitoneal hematoma: therapeutic options and surgical indication].
abstract: Retroperitoneal hematoma is a rare entity with clinical consequences that vary according to the speed and amount of bleeding. Thus, it may be asymptomatic, in which case it is usually diagnosed incidentally through imaging tests, or severe, in which case the most common symptoms are pain and hypovolemic shock. We report three cases of severe retroperitoneal hematoma. Although the literature on the subject describes a wide variety of causes, in all three patients the etiology was tumoral, consisting of one suprarenal myelolipoma, one renal adenocarcinoma and one suprarenal metastasis from bronchogenic adenocarcinoma. Computed tomography was the imaging test employed not only to determine the nature of the process (hematoma, abscess, tumor) but also to assess compression of adjacent structures and the occurrence of active bleeding. Conservative treatment consisting of volemic replacement and correction of coagulation was initially attempted. However, all three patients required emergency surgery due to hemodynamic instability in two patients and compression of the vena cava in the other.
