On Fisher's Syndrome : Report of Two Cases

The CTAT, in combination with various conventional tests such as EEG, was performed on patients with late onset epilepsy in whom epileptic seizures occurred at 20 or more years of age. Of 35 such patients, three were shown to have epileptic seizures arising from a brain tumor, and underwent neurosurgical operations. Each had been on anticonvulsants for eight months to seven years with no findings of brain tumors detected, even by neurological examinations, including EEG. The slower the growth of the tumor, as in the case of benign tumors, the more likely epileptic seizures will occur. Thus, it is stressed that performing a CTAT jointly is indispensible in diagnosing suc cases.
