PURPOSE
To describe the magnetic resonance imaging and histopathologic features of an orbital granular cell tumor.
METHODS
A 43-year-old man was initially examined with slowly progressive vertical diplopia. A firm mass was palpable through the left lower eyelid. Magnetic resonance imaging and histopathologic examinations were performed.
RESULTS
Magnetic resonance imaging disclosed a spindle-shaped mass involving the inferior oblique muscle. Histopathologic examination disclosed that the tumor cells, diagnosed as a granular cell tumor, had infiltrated the muscle fibers.
CONCLUSION
In the present case, these findings indicate that the granular cell tumor may develop in the inferior oblique muscle.
目的
描述眼眶颗粒细胞瘤的磁共振成像及组织病理学特征。
方法
一名43岁男性最初因缓慢进展的垂直性复视而接受检查。通过左下眼睑可触及一个质地坚硬的肿块。进行了磁共振成像和组织病理学检查。
结果
磁共振成像显示一个累及下斜肌的纺锤形肿块。组织病理学检查显示，诊断为颗粒细胞瘤的肿瘤细胞已浸润肌纤维。
结论
在本病例中，这些发现表明颗粒细胞瘤可能在下斜肌中发生。
