宫颈原发性粒细胞肉瘤的MRI诊断及文献复习
International Journal of Medical Radiology（2019）
Abstract
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.
