中文摘要：目的探讨肾黏液样小管状和梭形细胞癌(MTSCC)患者的影像学特征,以提高对本病的认识。方法选取14例MTSCC患者的临床及影像资料进行回顾性分析。结果CT平扫2例呈低密度,CT值分别为26 HU和28 HU,9例呈等密度,平均CT值为(35.25±3.28)HU,3例呈高密度,平均CT值为44.67 HU;增强扫描时皮质期CT值为(45.08±6.34)HU,髓质期CT值为(61.33±11.94)HU,排泄期CT值为(74.91±21.18)HU,强化程度以轻中度强化为主,排泄期达到强化高峰值,但各期强化程度均低于周围正常肾实质,7例病灶内出现坏死、囊变、钙化、出血等;8例患者行MRI检查,以稍长T_(1)稍长T_(2)信号表现为主,DWI呈明显高信号,ADC呈低信号,ADC值为0.50×10^(-3)~1.47×10^(-3) mm^(2)/s;1例患者行PET-CT检查,表现为肾实质内稍高密度结节伴FDG代谢增高,SUV_(max)值约5.8。结论MTSCC患者CT平扫大多呈等密度,密度较均匀,增强扫描呈轻中度延迟强化,MRI弥散受限,这些征象对诊断与鉴别诊断具有一定的价值。

外文摘要：Objective To explore the clinical and imaging characteristics of patients with renal mucinous tubular and spindle cell carcinoma in order to improve the clinical understanding of this disease.Methods Retrospective analysis was conducted on the clinical and imaging data of 14 patients with renal mucinous tubular and spindle cell carcinoma.Results 2 cases of CT plain scan showed low density,with CT values of 26 HU and 28 HU,respectively.9 cases showed equal density,with an average CT value of(35.25±3.28)HU.3 cases showed high density,with CT values of 42 HU,43 HU,and 49 HU.During enhanced scan,the CT values in the cortical phase were(45.08±6.34)HU,the CT values in the medullary phase were(61.33±11.94)HU,and the CT values in the excretory phase were(74.91±21.18)HU.The degree of enhancement was mainly mild to moderate,and the excretory phase reached a peak of enhancement.However,the degree of enhancement in each stage was lower than that of the surrounding normal renal parenchyma.In 7 patients,necrosis,cystic changes,calcification,bleeding,etc,appeared within the lesion;8 patients underwent MRI examination,with slightly longer T_(1)and slightly longer T_(2)signals as the main manifestation.They all showed significant high signal on DWI,while the ADC image showed low signal,with an ADC value of 0.50×10^(-3)~1.47×10^(-3)mm^(2)/s;one patient underwent PET-CT examination,which showed slightly high-density nodules in the renal parenchyma with increased FDG metabolism,with a SUVmax value of approximately 5.8.Conclusion CT plain scans of renal mucinous tubular and spindle cell carcinoma mostly show equal density,with relatively uniform density.Enhanced scans show mild to moderate delayed enhancement,and MRI diffusion is limited.These signs have certain value for diagnosis and differential diagnosis.
