Abstract
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.
