title: Renal artery aneurysm presenting as a chest mass.
abstract: An enlarging mass in the right chest in a 25-year-old woman was found at operation to be a false aneurysm of the renal artery. Preoperative diagnosis was not made despite an extensive workup including arteriography. Successful resection was carried out via a posterolateral thoracotomy. Although vascular reconstruction was not feasible. The danger of rupture of such an aneurysm from an incisional biopsy is emphasized.
