title: Unusual presentations of hypernephroma.
abstract: Two cases with varying presentations of renal adenocarcinoma are reviewed. The first patient manifested an unsuspected hypernephroma on intravenous pyelogram for ureteral colic by demonstrating a distorted collecting system and peripelvic extravasation of contrast material. The second case report is one of spontaneous subcapsular renal hemorrhage with hypernephroma.
