Abstract
We present a 56-year-old woman who came to our institution with a 6-month history of intracranial hypertension. Imaging studies showed diffuse dural enhancement, multiple lytic bone lesions and a tumor in the left ovary. A meningeal biopsy was performed; however, during this procedure the patient developed profuse dural hemorrhage and middle cerebral artery territory infarction and died a few hours later. The autopsy revealed a disseminated Brenner tumor that was infiltrating the intracranial dura mater. At this site neovascularization, vascular infiltration by malignant cells and a desmoplastic reaction were all observed, perhaps rendering the patient more susceptible to a dural hemorrhage during the biopsy. To our knowledge, this is the first report of a Brenner tumor presenting as dural metastases.
