We report a postoperative foreign body granuloma occurring in the thyroid bed after anterior cervical fusion. The magnetic resonance (MR) imaging finding of increased signal on T2-weighted images is atypical for this type of granuloma and is thought to be due to the large proportion of cellularity in the mass histologically. In the differential diagnosis of solid postoperative masses it is important to consider foreign body granuloma, as it can mimic neoplastic disease both clinically and radiographically.
我们报告了一例颈椎前路融合术后甲状腺床出现的术后异物肉芽肿。这种类型的肉芽肿在T2加权图像上磁共振（MR）成像表现为信号增强并不典型，据认为这是由于肿块组织学上细胞成分比例较大所致。在术后实性肿块的鉴别诊断中，考虑异物肉芽肿很重要，因为它在临床和影像学上都可能酷似肿瘤性疾病。
