Granular cell tumors (GCTs) are rare soft tissue tumor, originating from neural or perineural cells. We present a case of axillary GCT in a 69-year-old woman with breast cancer history and discuss the various radiologic findings. US revealed a circumscribed oval heterogeneous iso- and hyperechoic mass in the left axilla. Chest CT showed a well-defined, oval, and mildly enhancing mass in the left axilla on the lateral aspect of the pectoralis muscle. A final diagnosis of GCT was made through US-guided core needle biopsy. Follow-up US showed no significant changes in the axillary GCT. Familiarity with GCT may facilitate early diagnosis and subsequent management.
颗粒细胞瘤（GCTs）是一种罕见的软组织肿瘤，起源于神经或神经周围细胞。我们报告一例69岁有乳腺癌病史的女性腋窝颗粒细胞瘤病例，并讨论各种影像学表现。超声显示左腋窝有一个边界清晰的椭圆形不均匀等回声和高回声肿块。胸部CT显示在胸大肌外侧的左腋窝有一个边界清晰、椭圆形且轻度强化的肿块。通过超声引导下的粗针活检做出了颗粒细胞瘤的最终诊断。随访超声显示腋窝颗粒细胞瘤无明显变化。熟悉颗粒细胞瘤可能有助于早期诊断及后续治疗。
