眼眶病灶之電腦斷層攝影診斷

COMPUTED TOMOGRAPHY OF ORBITAL LESIONS

摘要


榮民總醫院自民國67年開始使用電腦斷層攝影(Computed Tomogrophy以二簡稱C.T),以來至69年七月底共有58例接受眼眶CT檢査,其中經開刀暨病理切片檢查證實者有28例,經臨床資料及追踪證實者有6例,複閱這34個病例,吾人可發現CT對眼眶病灶特別是眼球後腫瘤(retrobulbar tumor)具有高度靈敏的偵測能力。病灶的大小、位置、範圍以及侵蝕周圍組織結構的程度,可以很正確地提供眼科及神經外科醫師們作手術治療的參考,此外開刀後的評估及追踪檢查,CT無疑地也是最好的偵測工具。對病人而言即無傷害性,又倶高度的可靠性,故凡有疑似眼眶病灶及腫瘤者,CT應爲第一優先考慮之診斷步驟。

CT scanning has contributed greatly to the diagnosis and management of orbital diseases, particularly of lesions in the retrobulbar space. The location and extent of a tumor in the orbital region can be determined exactly, but it is seldom possible to identify the nature of the lesions. From our 58 patient's data, we had a high diagnostic rate (97%) in CT scanning of orbital lesions and we do believe that CT scanning should be the first step of diagnostic procedures, if orbital pathology were suspected clinically, particularly retrobulbar lesions.
