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.
