Intraventricular brain mass causing obstructive hydrocephalus: A rare location of prostate cancer metastasis

Abstract

Prostate cancer (PCa) metastasis to the brain is rare. When it does metastasize to the brain, it typically presents as a dural-based lesion. Generally, intraparenchymal metastasis indicates diffuse disease, which often carries a poor prognosis, and is typically discovered post-mortally. In the present case, we report a very rare occurrence of metastasis of PCa to the intraventricular space of the brain in a patient with a complex multimodal treatment history. With continued advances in cancer therapy, prolonged survival will result in more complex presentations of metastatic PCa to the brain, requiring unique management strategies.
