A review of 2,413 tumours operated over a 30-year period

Studying 2,413 cases of supratentorial brain tumors operated on a 30 years period, the author emphasizes appealing signs, pitfalls, and tumoral relapses. Epilepsy is the most frequent initial sign preceding headache and focal signs. We discuss the frequency of the epilepsy, the age of the first seizure, the location and the histological nature of the epiletogenic tumor, and the type of the seizures. In the end, we study diagnosis pitfalls such as long-standing epilepsy, ictal presentation, pitfalls due to metastases and the difficult problem of tumoral relapses.
