海綿狀血管瘤引發酒精相關之視交叉內猝出血症-病例報告

Apoplectic Optochiasmal Syndrome Due to Intrinsic Cavernous Hemangioma-Case Report

摘要


本篇報告一位42歲男性,發生急性現力減退現象,其病程和酒精有明顯關連。連續的視野變化顯示視傳導路徑前部有腫瘤壓迫現象,並且向原先定位的左側視神經迅速地朝視交叉和視徑移轉。電腦斷層掃描和磁核共振造影檢查發現上述部位有出血訊號。手術發現和病理報告證實是視神經軟腦膜內的海綿狀血管瘤。本例在臺灣尚屬首例,顯性出血的存在更是罕見。我們將對於特殊的病程以及發病機轉作詳細的探討。

A 42-year-old male suffered from acutely evolving visual loss after alcohol-drinking. Visual field changes suggested a mass within the left optic nerve extending its compression across the chiasm and encroaching on the left optic tract. Computerized tomography scanning and magnetic resonance imaging confirmed the presence of an overt hemorrhage. Swollen optic nerve and chiasm with intrinsic hemorrhage were found during surgery. Histological examination revealed a cavernous hemangioma. The clinical course, predisposing factors and mechanism of compression by the intrinsic cavernous hemangioma are discussed.
