RESUMO
OBJECTIVE: To report a case of GIST type retroperitoneal tumor with spontaneous rupture to the abdominal cavity causing acute abdomen secondary to hemoperitoneum. METHODS/RESULTS: We report the case of an 84 year-old man with history of BPH and chronic atrial fibrillation. He presented to the Emergency Department with diffuse abdominal pain, syncope and accompanying vegetative symptoms. Diagnostic work up showed a 19 cm retroperitoneal mass dependent of the left kidney with active bleeding and secondary hemoperitoneum. Left radical nephrectomy was performed with pathology report of gastrointestinal stromal tumor attached to the renal capsule. CONCLUSIONS: Spontaneous hemoperitoneum is a rare entity and it has various etiologies. It is rarely described in retroperitoneal tumors.

OBJECTIVE: Renal arterial-venous fistula is a low incidence clinical entity generally secondary to processes invasive to such organ. We report a new case with a bibliographic review, and evaluate the diagnostic and therapeutic approach. METHODS/RESULTS: We report the case of a patient who suffered a left flank knife wound and developed an arterial-venous fistula presenting with hematuria that was solved by selective embolization. CONCLUSIONS: Arterial-venous fistula is a low incidence entity, usually secondary to renal trauma (open or blunt) and invasive processes. Renal Doppler-Ultrasound is the initial diagnostic procedure when its diagnosis is strongly suspected and then angiography is both confirmatory and therapeutic.
