Renal ultrasonography showed a left subcapsular hematoma; the CT scan confirmed the finding and also showed renal scarring. However, a second CT scan showed pulmonary nodules suggestive of metastasis, a diagnosis that was confirmed by needle biopsy of pulmonary lesions. Recovery was obtained after chemotherapy and nephrectomy with a 3-year-follow-up.
