Cerebral metastasis secondary to prostatic adenocarcinoma is rare and it is usually a late complication in patients with widespread distant metastases. Here, we report two unusual cases of such a rare condition. Our first case presented with a large frontal contrast-enhancing lesion-associated calcification and a large tumor cyst as shown on computed tomography and magnetic resonance imaging. This is the fifth reported case of prostatic metastasis manifesting as a cystic intraparenchymal tumor in the literature. The second case presented with a large soft tissue mass in the scalp and this lesion appeared to invade through the skull and into the middle cranial fossa. He was not known to have prostate cancer before his initial presentation and it was only diagnosed following histology results of the scalp lesion.
前列腺腺癌继发脑转移罕见，通常是广泛远处转移患者的晚期并发症。在此，我们报告两例这种罕见情况的不寻常病例。我们的首例病例经计算机断层扫描和磁共振成像显示，额叶有一个强化的大病灶伴钙化以及一个大的肿瘤囊肿。这是文献中第五例报道的前列腺转移表现为脑实质内囊性肿瘤的病例。第二例病例表现为头皮有一个大的软组织肿块，该病灶似乎穿透颅骨侵入中颅窝。他在初次就诊前未知患有前列腺癌，只是在头皮病变的组织学结果出来后才得以确诊。
