title: Malignant priapism in a patient with metastatic prostate adenocarcinoma.
abstract: Metastases to the penis due to a primary carcinoma of the prostate are rare. In approximately half of the patients, malignant priapism is the main symptom. This study reports on a case of malignant priapism, caused by a direct and metastatic infiltration of the corpora cavernosa by a prostatic adenocarcinoma. Sonography gave hints, the magnetic resonance imaging verified the infiltration and aspiration cytology verified the carcinoma. Hemodynamics, evaluated by Doppler sonography, and intracavernosal blood gas analysis demonstrated a mixed high-low priapism without need of therapy.
