Spontaneous Intracranial Epidural Hematoma Following Thoracolumbar Schwannoma Removal

We report a case of spontaneous intracranial epidural hematoma following the intraoperative course of a patient who had undergone surgical removal of a thoracolumbar schwannoma in olivo-ponto-cerebellar atrophy. To our knowledge there is no reported case in which the thoracolumbar schwannoma removal was followed by such a complication. Mechanical events leading to this complication are unclear. Abnormal results of a neurological examination in the early postoperative period should suggest this possibility.
