Abstract

複雑部分発作重積後、記憶障害が生じた症例を経験したので報告する。症例は47歳、女性。47歳時より眩量、嘔気とともに健忘が出現した。頻回に出現するようになり当科初診となった。その後意識変容をきたし脳波検査にて複雑部分発作重積状態と診断された。重積終了後、記憶障害が出現し、また頭部MRIにおいては両側海馬領域に異常信号を認めた。記憶障害は記銘障害が主体であり、海馬病変が記憶障害の責任病巣と思われた。従来の報告によるとこの異常信号は重積により生じる浮腫と推測されている。本症例においても記銘障害の改善とともにMRI上の異常信号もみられなくなってきており、異常信号は浮腫であると思われた。

We reported a case of complex partial status epilepticus with memory distur bance. A 47-year-old woman had suffered from complex partial seizures with dizzi ness and nausea. She consulted our hospital because her seizures had become frequent. She suffered from complex partial status epilepticus (CPSE). We examined her EEG and gave her an injection of intravenous diazepam. She recovered from CPSE but acquired memory disturbance. We examined her brain by MRI and detected high signal intensity on bilateral hippocampus on the T2 image. Her memory disturbance mainly consisted of memory input dysfunction. Therefore, we thought her memory distur bance was due to dysfunction of the hippocampus. As reported, high signal intensity on the MRI T2 image after CPSE was considered to be edema. Our case recovered a little from the memory disturbance and we observed no significant abnormal intensity on the MRI T2 image. It is suggested that the high signal intensity was caused by edema.
