摘要

自十五公釐胚胎期開始發育之鑽動脈與眼動脈和中腦膜動脈之形成有非常密切的關係。在這些動脈的發育過程中可能產生數種形式之變異。本女性病例出現左眼視力減退之症狀歷時三個月。磁振造影檢查發現－蝶鞍上腫瘤。數位式血管攝影檢查偶然發現源自眼動脈之中腦膜動脈。此種中腦膜眼動脈被認為是因為鏡動脈之眼窩上部份退縮失敗以及鑽動脈之眼窩上部份和面頷部分之異常連接所造成的。此蝶鞍上腫瘤經手術切除後病理報告證實為腦膜瘤。

The embryonic stapedial artery begins development at 15mm embryo stage and closely relates to the formation of the ophthalmic and middle meningeal arteries. Several types of anomalies may occur during the development. A woman incurred decreased left visual acuity for three months. MRI revealed a suprasellar tumor. Incidentally, digital subtraction angiography (DSA) revealed that the right middle meningeal artery arose from the ophthalmic artery. It was regarded as an ophthalmic- middle meningeal artery (OMMA) due to failure of involution of supraorbital stapedial division and connection between the supraorbital and maxillofacial stapedial divisions. After surgical excision of the tumor, the patient was discharged smoothly. Pathology showed meningioma.
