Massive hemothorax secondary to metastatic renal carcinoma

We present the case of a 78-year-old man with a past history of nephrectomy for renal cell carcinoma who was brought to the emergency room in hypovolemic shock after suddenly collapsing at home. A chest roentgenogram taken on admission showed a large pleural effusion on the right with a mediastinal shift to the left. A contrast computed tomographic scan of his chest excluded aortic dissection. An emergency right thoracotomy was performed, which revealed a chest wall tumor that was bleeding profusely. The tumor was biopsied after the bleeding was controlled. The histologic report revealed metastatic renal cell carcinoma, which is a rare cause for a spontaneous massive hemothorax.
