Posttraumatic pseudomeningoceleの1例

Posttraumatic Pseudomeningocele―A Case Report

はじめに

　Pseudomeningoceleは頭部外傷後に発症する，非常に稀な合併症の1つである。小児に多く合併し，そのほとんどは無症状で自然消失する^1）。しかし，貯留液の増大による神経症状の出現や，長期的に残存すると拡大性頭蓋骨骨折を合併することもあり，この場合には積極的な治療が必要となる。

　今回われわれは，頭部外傷後にpseudomeningoceleを合併し，皮下ドレナージと包帯による外部からの圧迫で，良好な結果を得た症例を経験したので報告する。

Abstract

　Pseudomeningocele is a rare complication of head trauma.　An 7-year-old male child who fell from playground equipment was admitted to hospital with lambdoid sutural diastatic fracture.　As epidural and subgaleal fluid collections gradually developed from the subsequent day of admission, a subgaleal drain was placed for cerebrospinal fluid (CSF) diversion.　In addition, the scalp just over the fractured segment was compressed by band after drainage whereby the CSF leak was stopped.　On the basis of our experience with this case, we suggest that appropriate management enables repair of posttraumatic pseudomeningocele in early stages of injury.
