Eleven patients with anterior and deep orbital masses had A-scan ultrasonography. The ultrasonograms were all similar and demonstrated a dermoid-like pattern of low internal reflectivity and a high-rising, double-peaked posterior surface spike. Although the postoperative pathologic findings in seven cases confirmed the clinical diagnosis of dermoid cyst, other lesions, such as epidermoid cyst, sebaceous cyst, Graves's myopathy, and Ewing's sarcoma were found to show a similar ultrasonographic pattern. This stresses the importance of computed tomography in the diagnosis of orbital tumors.
11例患有眶前部深部肿物的患者接受了A超超声检查。超声图像均相似，显示出类似皮样囊肿的内部低反射模式以及高耸的双峰后表面波峰。尽管7例患者的术后病理结果证实了皮样囊肿的临床诊断，但发现其他病变，如表皮样囊肿、皮脂腺囊肿、格雷夫斯肌病和尤因肉瘤，也表现出类似的超声图像模式。这强调了计算机断层扫描在眼眶肿瘤诊断中的重要性。
