Multifocal primary intracerebral malignant fibrous histiocytoma - Case report

Abstract

A 58-year-old female presented with a unique case of multifocal primary intracerebral malignant fibrous histiocytoma (MFH) manifesting as partial seizure. Neuroimaging showed a mass lesion in the right frontal lobe, which was totally removed. The histological diagnosis was MFH. Follow-up neuroimaging one month after surgery showed another lesion rapidly growing in the left frontal lobe. This lesion was totally removed, and identified as MFH. Her condition gradually worsened. Neuroimaging performed 3 months after first operation revealed bilateral recurrence. She died of respiratory failure 7 months after the initial diagnosis of MFH. Primary intracranial MFH is an extremely rare entity with only 31 cases of solitary tumor previously reported.
