Temporal Lobe Epilepsy Associated with Old Intracerebral Hemorrhage due to Capillary Telangiectasis in the Temporal Lobe: Case report

　毛細血管拡張症による陳旧性側頭葉内出血に伴う側頭葉てんかんの1例を報告した。術中皮質電位では側頭葉内側部と外側部に非同期性の突発性異常波がみられたが，側頭葉外側切除後も海馬から突発性異常波が頻発していた。組織学的には，側頭葉内に陳旧性脳内出血に伴うグリオーシスとヘモジデリン沈着がみられ，これらが海馬にも影響を与え，てんかんの発症に関与したものと思われた。

A case of 45-year-old female, who presented with temporal lobe epilepsy was reported. The patient was found to have old intracerebral hemorrhage due to capillary telangiectasis in the temporal lobe. On the in-traoperative electrocorticography, frequent paroxysmal activities were recorded independently both on the medial and lateral aspects of the temporal lobe. Even after resection of the lateral temporal lobe, frequent paroxysmal discharges were noted on the hippo-campus. Histologically, there are astrogliosis and he-mosiderin deposits in the white matter around the tel-angiectasis and the old hematoma.
