Gliofibroma with extensive calcified deposits.

Gliofibroma is a rare astrocytic neoplasm of young people that shows abundant deposition of collagenous matrix around glial cells. It shares some clinical and pathologic features with desmoplastic cerebral astrocytoma of infancy or desmoplastic infantile ganglioglioma. However, histogenesis or clinical behavior of these tumors is not fully known. Here, we report a case of gliofibroma with unusual extensive calcification which complicated radiologic as well as pathologic diagnosis.
