The authors report the echographic characteristics of a rare orbital granular cell tumor and correlate these findings with histopathology. A 56-year-old woman presented with proptosis. Complete ophthalmic and ultrasound examinations were performed. Ultrasound revealed an oval, well-outlined orbital mass in the intraconal space with low-medium reflectivity and regular internal structure. An orbitotomy with complete excision of the tumor was performed. Histopathologic evaluation showed sheets and nests of cells with abundant eosinophilic and granular cytoplasm in a uniform distribution throughout the lesion. The echographic characteristics correlated well with the morphologic surgical findings and the histologic architecture. This is the first report describing the echographic characteristics of orbital granular cell tumor.
作者报告了一种罕见的眼眶颗粒细胞瘤的超声特征，并将这些发现与组织病理学相关联。一名56岁女性出现眼球突出。进行了全面的眼科和超声检查。超声显示眶内肌锥内有一个椭圆形、轮廓清晰的眼眶肿块，具有低-中等回声，内部结构规则。进行了肿瘤全切的眼眶切开术。组织病理学评估显示，细胞呈片状和巢状，整个病变中嗜酸性和颗粒状细胞质分布均匀。超声特征与手术形态学发现和组织学结构密切相关。这是第一篇描述眼眶颗粒细胞瘤超声特征的报告。
