本文報告八例急性眼窩偽腫瘤之病例,男女各4例,單側比雙側為7比1,乎均年齡44歲。其臨床共同特徵為眼痛、眼窩和眼瞼之炎性徵候、突眼、視力模糊;此症須先排除感染性眼窩峰窩組織炎、甲狀腺性眼窩症或其他特殊病因之眼窩發炎後才能作診斷。超音波和電腦斷層攝影為診斷和分類之重要工具。本病對類固醇治療反應良好,但有復發之傾向。
The clinical manifestations, laboratory findings, ultrasonographies, CT scan findings and classifications of 8 cases of acute orbital pseudo-tumors are presented. The possibilities of orbital cellulitis, Graves' orbitopathy, orbital lymphoma or other orbital inflammation due to specific causes should be ruled out before making a diagnosis. Acute orbital pseudotumors may develop over days or weeks and be dominated by pain, neuropraxia and inflammatory clinical features. They may be diffuse or primarily localized to a specific tissue of the orbit. According to CT scan findings, acute pseudotumor can be differentiated into five patterns: diffuse, anterior, posterior, lacrimal and myositis types. The acute form pseudotumors respond well to high doses of oral corticosteroids tapered over a period of months, however they may recur or become chronic, in which case they respond less well.
