Primary intracranial extradural Burkitt-type lymphoma. A unique presentation with unilateral loss of vision in a child.

An unusual case of primary extranodal Burkitt's-type lymphoma of the frontal base dura and adjacent bone with intradural invasion is reported in a 5-year-old child who presented with unilateral loss of vision in the left eye. Tissue diagnosis was obtained through a craniotomy and the patient received radiotherapy plus intravenous and intrathecal chemotherapy. The tumor regression and improvement in vision was well documented by means of CT and visual evoked potential studies (VEP). A review of the literature on this exceptionally rare tumor is presented.
