Spontaneous retroperitoneal hemorrhage is a quite rare disease. Appropriate treatment should be done after the cause of the disease had been detected. A complete clinical information and detailed radiologic examination are required for accurate diagnosis. In this study, a 76-year-old female patient who was evaluated in the emergency department of our hospital and found to have an abruptly developed retroperitoneal hemorrhage and hemorrhagic shock due to a big renal mass is presented. The patient required immediate radical nephrectomy. Pathological diagnosis was chromophobe type renal cell carcinoma with an invasion into the perinephric fat (pT3a). Subsequent staging after the operation failed to indicate any metastaic disease and there was no local or distant metastates in the first year follow-up.
