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.
前列腺原发性癌转移至阴茎的情况较为罕见。大约半数患者中，恶性阴茎异常勃起是主要症状。本研究报告了一例由前列腺腺癌直接浸润和转移至海绵体导致的恶性阴茎异常勃起病例。超声检查提供了线索，磁共振成像证实了浸润，抽吸细胞学检查证实了癌症。通过多普勒超声评估的血流动力学以及海绵体内血气分析显示为无需治疗的混合性高低度阴茎异常勃起。
