摘要

超音波檢查可偵檢眼窩腫瘤之位置、大小及基本組織型態（囊腫性、實質性、血管瘤性、浸潤性）。對於眼窩炎性病症如偽腫瘤或蜂窩織炎，充血性病症如甲狀腺突眼症或眼窩出血也有極高之可信度。而由於高度近視或青光眼引起之假性突眼症，也可憑此偵檢。本文介紹各型突眼症之超音波影像，並就60例經病理或臨床追踪檢查證實病因之單側突眼症，複閱其超音波影像，評估其診斷率為88%。超音波檢查仍有其限度，無法診斷顱內病灶或血管性病灶引起之突眼症；但此種檢查無傷害，可反覆檢查且花費較少。對於眼窩軟組織異常引起之突眼症之初步評估及追綜檢查極有助益。

With ultrasonography, orbital tumors are clearly demonstrated in terms of their location, size, as well as the basic tissue type (cystic, solid, angiomatous or infiltrative). Other orbital disorders are defined by this technique also, including inflammatory conditions such as celluiftis or pseudotumor, congestive conditions such as dysthyroid exophtbalmos and orbital hemorrhage. Pseudoproptosis due to large globe or shallow orbit can also be detected.
In a series of 60 consecutive cases with unilateral exophthalmos evaluated with ultrasonography, diagnosis of tumors was made in 24 cases, dysthyroid exophthalmos 12 cases, inflammatory conditions 9 cases, pseudoproptosis 7 cases, normal ultrasound studies 8 cases, orbital hemorrhage 1 case. The overall accuracy for evaluating the causes of exophthalmos was 88%, while the sensitivity of orbital tumor diagnosis was 84%.
Although there are some limitations in evaluation of intracranial and vascular etiologies of exophthalmos, diagnostic ultrasonography is capable of detecting orbital tumors and distinguishing them from inflammatory, congestive, and other causes of exophthalmos. The examination is non-invasive, well-tolerated, painless and economic. It may be considered as a first-step evaluation and follow-up examination for any patient with unilateral exophthalmos.
