Primary fibrosarcoma of brain.

This is a case presentation of a young patient with an intracranial space-occupying lesion following multiple episodes of generalised tonic clonic seizures for the last 20 years. Such a long latency period between the onset of fits and the discovery of an intracranial lesion is highly unusual in malignant brain tumours. This lesion was excised completely and proved to be a primary lesion of the brain - fibrosarcoma. These rare tumours of mesenchymal origin in the central nervous system are very rare.
