title: Incidental detection of carcinoma of the prostate while staging carcinoma of the rectum with transrectal ultrasound.
abstract: This case report describes the unanticipated results of a transrectal ultrasound performed to stage a cancer of the rectum. During sonography, the normally dense prostate peripheral zone produced weak echoes indicating the existence of an unexpected carcinoma of the prostate. The presence of extensive prostate cancer was subsequently verified by biopsy.
