摘要
目的探讨原发性纵隔混合型恶性生殖细胞瘤(MGCT)的影像学表现及特征。方法选择2016年1月-2021年3月收治的31例MGCT患者为研究对象,所有患者均行胸部CT平扫和增强检查,其中15例行PET/CT检查,对其临床资料进行分析。结果所有患者均出现囊实性肿块,呈类圆形或者分叶状,其病灶平均直径为(15.6±2.3)cm,最大径为9.1-20.2 cm;经增强扫描后,可见迂曲血管影状强化,静脉期血管影明显增加,与动脉期相比,瘤灶内部实性部分可见明显强化,且呈现出不均匀渐进性强化的特点;其中行PET/CT检查15例患者的病灶最大化标准化摄取值(SUVmax)为(6.8±1.6)。结论在MGCT患者的临床诊断中,通过行CT检查,可以获得清晰的影像学特征,且联合PET/CT检查,能够及时发现微小病灶,提高诊断准确率。
Objective To investigate the imaging manifestations and characteristics of primary mediastinal malignant reproductive cell tumor(MGCT).Methods 31 MGCT patients admitted in our hospital from January 2016 to March 2021.All patients underwent chest CT leveling and enhancement examination,including 15 PET/CT tests and retrospective analyzed their clinical data.Results All patients had cystic solid mass,circular or foliate,with average lesion diameter(15.6±2.3)of 9.1-20.2 cm;after enhanced scan,the lesion was enhanced and progressive;15 PET/CT patients had standardized uptake(SUVmax)of(6.8±1.6).Conclusions In the clinical diagnosis of MGCT patients,clear imaging characteristics can be obtained through CT examination,and combined with PET/CT examination can detect small lesions in time and improve the diagnostic accuracy.
