A 66-year-old woman reported fullness in the right ear for 6 months before admission. A submucosal mass shown by MR imaging and CT to arise in the prestyloid parapharyngeal space was the cause of her symptoms. Histologically, the mass proved to be a rhabdomyoma, a rare benign neoplasm, that arose from the muscular wall of the pharynx.
一名66岁女性在入院前6个月诉说右耳有胀满感。磁共振成像(MR)和计算机断层扫描(CT)显示,一个位于茎突前咽旁间隙的黏膜下肿块是其症状的病因。组织学检查证实,该肿块是一种横纹肌瘤,一种罕见的良性肿瘤,起源于咽肌壁。
