摘要

過去已有報導指出以高解析度快速自旋回音磁振造影可表現詳細的海馬迴解剖結構及定位海馬迴位置上的病灶，我們報導使用高解析度快速自旋回音磁振造影在一有複雜性熱痙攣及發熱性癲癇重積的兩歲半小孩，表現出海馬迴訊號及形態的改變同時合併一同側脈絡間隙水囊。我們預測此脈絡間隙水囊可能與癲癇重積發生的原因及在癲癇重積發生後同側海馬迴好發病變有關。以高解析度快速自旋回音磁振造影表現癲癇重積的海馬迴變化合併同側脈絡間隙水囊是很少被報導的，文章中會討論到癲癇在海馬迴變化的生理病理學。

High-resolution fast spin-echo (FSE) magnetic resonance (MR) technique has been reported to delineate anatomic detail and localize structural abnormality of the hippocampus very well. MR findings of the hippocampus are reported as found in a two and a half-year-old child who had complex febrile seizures and febrile status epilepticus associated with an ipsilateral choroidal fissure cyst; the FSE MR technique was used. There was signal and morphologic change of the hippocampus with coexisting ipsilateral choroidal fissure cyst in this patient. The possible cause of status epilepticus and unilateral vulnerability of the hippocampus was presumed related to the choroidal fissure cyst. FSE MRI findings of the hippocampus with coexisting choroidal fissure cyst in status epilepticus has rarely been reported. Pathophysiology of hippocampal change in epilepsy is discussed.
