| 目的 观察基于增强MRI"草莓征"鉴别囊性为主单发脑转移癌与胶质瘤的价值。方法 回顾性纳入囊性为主(囊性比例大于50%)单发脑转移癌(转移癌组)34例及单发胶质瘤(胶质瘤组)43例;分析基于对比增强 T1WI(CE-T1WI)"草莓征"鉴别二者的价值。结果 转移癌组"草莓征"检出率为44.12%(15/34),原发癌包括肺腺癌6例(6/15,40.00%)、肺小细胞癌3例(3/15,20.00%),以及肺鳞癌、乳腺癌、结肠腺癌、子宫内膜样癌、输卵管腺癌和直肠黑色素瘤各1例(1/15,6.67%);胶质瘤组"草莓征"检出率为18.60%(8/43),均见于WHO 4级肿瘤。转移癌组"草莓征"检出率高于胶质瘤组,且与患者性别无关(P=0.442)。以"草莓征"鉴别囊性为主单发脑转移癌与胶质瘤的敏感度、特异度、准确率、阳性预测值及阴性预测值分别为44.12%、81.40%、64.94%、65.22%及64.81%。结论 CE-T1WI所示"草莓征"有助于鉴别囊性为主单发脑转移癌与胶质瘤。 |

| Objective To observe the value of enhanced MRI "strawberry sign" for differentiating solitary predominantly cystic brain metastasis and glioma. Methods Thirty-four patients with solitary predominantly cystic (cystic proportion greater than 50%) brain metastasis (metastasis group) and 43 with solitary predominantly cystic glioma (glioma group) were retrospectively enrolled, and the value of "strawberry sign" showed on contrast enhanced T1WI (CE-T1WI) for differentiation was analyzed. Results The detection rate of "strawberry sign" in metastasis group was 44.12% (15/34), and the primary cancer was lung adenocarcinoma in 6 cases (6/15, 40.00%), small cell lung cancer in 3 cases (3/15, 20.00%), as well as lung squamous cell carcinoma, breast cancer, colon adenocarcinoma, endometrioid carcinoma, fallopian tube adenocarcinoma and rectal melanoma each in 1 case (1/15, 6.67%). Meanwhile, the detection rate of "strawberry sign" in glioma group was 18.60% (8/43), and all were observed in WHO grade 4 gliomas. The detection rate of "strawberry sign" in metastasis group was higher than that in glioma group, which was not related to patients' gender (P=0.442). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of "strawberry sign" for differentiating solitary predominantly cystic brain metastasis and glioma was 44.12%, 81.40%, 64.94%, 65.22% and 64.81%, respectively. Conclusion "Strawberry sign" showed on CE-T1WI was helpful for differentiating solitary predominantly cystic brain metastasis and glioma. |
