A case of nontraumatic renal subcapsular hematoma was reported. The patient was 67-year-old woman, who complained of the left flank colic pain and macroscopic hematuria without any history of the left flank injury. Ultrasonography demonstrated left renal solid mass. Excretory pyelography demonstrated a large mass involving the left kidney with medial displacement of collecting system. Retrograde pyelography confirmed the presence of a left renal mass with pressure on the pelvis and calyces. A renal arteriography revealed flattening of the lateral border of the left kidney and failed to demonstrate either tumor vasculature or evidence of vascular disease. Left nephrectomy was performed and the removed kidney weighed 118g, sized 10.5×6.0×5.5 cm. Left renal subcapsular hematoma was confirmed with no bleeding in the perinephric space. Histological examination failed to reveal any causes of hematoma.
