Granular cell myoblastomas are uncommon, typically benign tumors. Involvement of the esophagus is rare, and frequently they are asymptomatic. We report a granular cell myoblastoma involving the cervical esophagus in a patient who had paralysis of the true vocal cord and progressive dysphagia. At MR imaging, the circumscribed mass was hypointense on T1-weighted images and mildly hyperintense on T2-weighted images, with homogeneous contrast enhancement.
颗粒细胞瘤是一种罕见的、通常为良性的肿瘤。食管受累情况罕见，且通常无症状。我们报告了一例累及颈段食管的颗粒细胞瘤患者，该患者伴有真性声带麻痹和进行性吞咽困难。在磁共振成像（MR）上，该边界清晰的肿块在T1加权像上呈低信号，在T2加权像上呈轻度高信号，增强扫描呈均匀强化。
