Myxopapillary ependymoma of the temporal lobe--report of a rare case of temporal lobe epilepsy.

Myxopapillary ependymomas are a benign variant of ependymomas, occurring almost exclusively in the cauda equina region. We report an extremely rare case of myxopapillary ependymoma located in the left anterior temporal lobe. A 22-year-old man is presented with intractable seizures of 2 years duration with no focal neurologic deficits. Imaging of the brain revealed a well-circumscribed heterogeneous mass in the left anterior temporal pole with no connection to the ventricles. Imaging of the spine was normal. The patient underwent surgical removal of the tumor and at follow-up 4 months after surgery, there was improvement in his memory and speech along with complete cessation of seizures. Microscopic examination revealed the tumor to be a myxopapillary ependymoma, further confirmed by histochemical and immunohistochemical stains. To the best of our knowledge, this is the first documentation of myxopapillary ependymoma at this location and consequently, the first case to clinically present as intractable temporal lobe epilepsy.
