背景:

頭蓋内気管支原性嚢胞（BC）は極めて稀である。我々の知る限りでは，中頭蓋窩，後頭蓋窩，下顎窩に病変を有するBCの報告は初めてである．

BACKGROUND: Intracranial bronchogenic cysts (BCs) are extremely rare. To our knowledge, this is the first report of a BC in which lesions involve the middle and posterior cranial fossa, as well as the infratemporal fossa.

ケースの説明:

症例は頭蓋神経機能障害を2年間患っていた38歳女性である。磁気共鳴画像診断では中窩と後窩に頭蓋底通信病変が認められた。手術は下顎窩アプローチで行った。病理組織学的検査と免疫組織化学的検査の結果、最終診断はBCとなった。患者の神経機能障害は半年後の経過観察で部分的に改善した。

CASE DESCRIPTION: We present the case of a 38-year-old woman who suffered from a cranial nerve dysfunction for 2 years. Magnetic resonance imaging showed that there were skull base communication lesions across the middle and posterior fossa. The patient was operated on through an infratemporal fossa approach. The final diagnosis was BC after histopathologic examination and immunohistochemical verification. The patient's neurologic dysfunction was partially ameliorated at the half-year follow-up.

結論:

頭蓋内BCはまれである。しかし、エッジ強調や頭蓋外進展を伴う嚢胞性病変の鑑別診断では考慮すべきである。

CONCLUSIONS: Intracranial BCs are rare. However, they should be considered in the differential diagnosis for cystic lesions with edge enhancement or extracranial extension.
