A 45 year
old woman with a two year history of infrequent headaches
presented with a seizure 4 years ago and was found to have a
nonenhancing left posterior temporal and parietal lesion
that was stereotactic biopsied and shown to be a low grade
anaplastic astrocytoma grade 3.
She was subsequently
treated with radiotherapy, and later with chemotherapy.
Despite treatment, the tumor recurred and radiosurgery was
performed six months later.
Six months following
radiosurgery she developed visual field loss and speech
problems. SPECT was normal.
Several weeks
following surgery, a MRI showed a questionable area of
enhancement in the resection bed adjacent to the occipital
horn.
