Metastatic prostate cancer mimicking chronic subdural hematoma: a case report and review of the literature.

Cancer of the prostate is extremely common and is well known to metastasize to the pelvic lymph nodes and axial skeleton (vertebral column, pelvis, cranium, and proximal femur). However, reports of intracranial metastasis are rare and commonly discovered postmortem. Moreover, metastatic lesions mimicking subdural hematoma are extremely rare and are uncommonly reported in the literature. We found only three such cases in the literature. We present a unique case of metastatic prostate cancer presenting with headaches after head trauma with classic radiologic findings of subdural hematoma. The diagnosis may have been made sooner with preoperative magnetic resonance imaging.
