摘　　要：目的探讨宫颈原发性粒细胞肉瘤(PGS)的临床病理学特征、MRI诊断及鉴别诊断。方法分析1例以阴道流血为首发症状的宫颈PGS女性病人(39岁)的临床表现、MRI征象及病理学特点,并复习相关文献。结果 PGS在MRI上表现为环绕宫颈生长的孤立性肿块,T2WI稍高信号,T1WI低信号,信号较均匀,DWI明显扩散受限,但宫颈黏膜线完整,增强后均匀中度强化。结论宫颈PGS罕见,术前诊断困难。宫颈PGS容易误诊,常规MRI结合DWI有助于临床诊断与术前评估。Objective To investigate the clinicopathological features, MRI diagnosis and differential diagnosis of primary granulocytic sarcoma (PGS) of cervix. Methods The clinical features, MRI appearances, and pathological characteristics of cervical PGS were analyzed in a 39-year-old female patient with vaginal bleeding as the first symptom, and the relative references were reviewed. Results The PGS presented as a solitary mass embracing the cervix on MRI, it revealed homogeneous high signal on T2WI, low signal on T1WI, and significantly limited diffusion on diffusion-weighted imaging (DWI). The cervical mucosa was intact and was homogeneously moderately enhanced. Conclusion PGS of cervix is a rare condition, which makes it difficult to diagnosis before operation. PGS of cervix is easy to be misdiagnosed. Combining DWI and conventional MRI improves both clinical diagnosis and preoperative evaluation.
