Dissemination of prostate adenocarcinoma to the skull base mimicking giant trigeminal schwannoma: anatomic relevance of the extradural neural axis component.
We report an unusual case of a large metastatic lesion from prostate adenocarcinoma with its epicenter located in Meckel's cave. The patient presented with acute neurological deterioration due to pontomesencephalic, cranial nerve, and temporal lobe compression. This lesion radiologically mimicked a giant trigeminal schwannoma. Complete surgical resection was achieved with improvement in the performance status of the patient. The anatomic relevance the extradural neural axis component in the process of dissemination of prostate adenocarcinoma to the skull base is highlighted.
