Solitary intradural fibrochondroma in a 16-year-old boy.

The following case report is that of a 16-year-old boy who had a solitary benign intracranial parietal fibrochondroma. He presented with a 2 month history of headache. A cranial CT demonstrated an isodense, non-contrast enhancing, extra-axial lesion with decreased central opacity and flecks of hyperdensity consistent with calcification. MRI revealed a heterogeneous well circumscribed mass which had an increased signal on T2-weighted images; there was no enhancement with gadolinium. This lesion was totally removed and had histopathological features of a benign chondroma with a fibrocartilaginous character. The literature of this rare tumour is summarized.
