A 31-year-old woman developed low-grade fever and pain and swelling of the masticatory muscles. A T2-weighted magnetic resonance image showed high signal intensity in these muscles. Coxsackie B3 and echo 30 viruses were detected from a nasopharyngeal swab and feces, respectively. The clinical symptoms accompanied a marked decline in the serum immunoglobulin G level with progressive eosinophilia. Her symptoms disappeared by 8 weeks after onset. She was diagnosed as having masticator myopathy, which has rarely been reported in humans. The present case suggests that masticator myopathy is associated with coxsackie or echo virus infection.
一名31岁女性出现低热以及咀嚼肌疼痛和肿胀。T2加权磁共振成像显示这些肌肉信号强度增高。分别从鼻咽拭子和粪便中检测到柯萨奇B3病毒和埃可30病毒。临床症状伴有血清免疫球蛋白G水平显著下降及进行性嗜酸性粒细胞增多。她的症状在发病8周后消失。她被诊断为咀嚼肌肌病，该病在人类中鲜有报道。本病例提示咀嚼肌肌病与柯萨奇或埃可病毒感染有关。
