To describe the magnetic resonance imaging and histopathologic features of an orbital granular cell tumor.
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.
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.
In the present case, these findings indicate that the granular cell tumor may develop in the inferior oblique muscle.
描述眼眶颗粒细胞瘤的磁共振成像及组织病理学特征。
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。
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。
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。
