Orbital cholesteatomas and fibromyxomas are relatively rare, but in echographic tissue differentiation both should be taken into consideration to avoid misdiagnosis. An orbital cholesteatoma may be mistaken for a hemangioma or a mixed tumor. Orbital cholesteatomas are distinguished by the following characteristics; high reflectivity, usually typical subperiostal location, wall or bone spikes, incompressibilty and immobility. Fibromyxomas are recognizable by their relatively regular structure, low to medium reflectivity and marked vascularity; they are poorly outlined, often showing signs of cellulitis.

眼眶胆脂瘤和纤维黏液瘤相对少见，但在超声组织鉴别诊断中，二者均应予以考虑以避免误诊。眼眶胆脂瘤可能被误诊为血管瘤或混合瘤。眼眶胆脂瘤具有以下特征：高回声、通常典型的骨膜下位置、壁或骨嵴、不可压缩性和固定性。纤维黏液瘤可通过其相对规则的结构、低至中等回声和明显的血管性来识别；它们边界不清，常显示蜂窝织炎的征象。
