Primary meningeal malignant fibrous histiocytoma with cerebrospinal dissemination and pulmonary metastasis.

Primary intracranial malignant fibrous histiocytoma (MFH) is very rare, and not much is known about its clinical features. The authors report a case of left temporal leptomeningeal MFH, with consequent cerebrospinal fluid (CSF) dissemination and pulmonary metastasis. The clinical features of this case and the therapeutic prognosis of 17 cases reported previously in the literature were reviewed.
