A 40-year-old man presented with weakness of neck extensor muscles. Cervical magnetic resonance imaging showed high-intensity areas in muscles of the left lateral cervical region on T2-weighted images. Fluorodeoxyglucose-positron emission tomography scan demonstrated striking fluorodeoxyglucose uptake by multiple skeletal muscles of the neck, chest, and abdominal region. Muscle biopsy demonstrated peripheral T-cell lymphoma, unspecified. The diagnosis was primary skeletal muscle peripheral T-cell lymphoma. Primary skeletal muscle non-Hodgkin's lymphoma of T-cell immunophenotype is extremely rare and fluorodeoxyglucose-positron emission tomography demonstrated striking fluorodeoxyglucose uptake in multiple skeletal muscles and served as a quite useful modality for the diagnosis of this patient.
一名40岁男性因颈部伸肌无力就诊。颈椎磁共振成像显示，在T2加权图像上左侧颈部区域肌肉出现高强度区域。氟脱氧葡萄糖正电子发射断层扫描显示，颈部、胸部和腹部的多处骨骼肌有明显的氟脱氧葡萄糖摄取。肌肉活检显示为未特指的外周T细胞淋巴瘤。诊断为原发性骨骼肌外周T细胞淋巴瘤。T细胞免疫表型的原发性骨骼肌非霍奇金淋巴瘤极为罕见，氟脱氧葡萄糖正电子发射断层扫描显示多处骨骼肌有明显的氟脱氧葡萄糖摄取，对该患者的诊断是一种非常有用的方法。
