Objective To investigate the imaging features of MiT family translocation renal cell carcinoma(MiT RCC)and its differential diagnostic value with renal clear cell carcinoma(CCRCC)and papillary renal cell carcinoma(PRCC).Methods CT and MRI images of 11 patients with MiT RCC confirmed by surgery and pathology were selected.The ima-ging characteristics of the patients,such as gender,age,size,morphology,hemorrhage,pseudocapsule,enhancement pat-tern,growth pattern and invasion of surrounding tissues were analyzed,and the imaging characteristics were compared with those of 11 CCRCC and 11 PRCC.Results Among the 11 patients with MiT RCC,there were 3 males and 8 females.The average age of the patients was(33.18±17.41)years.The results of analysis among 11 MiT RCC,11 CCRCC,and 11 PRCC showed that there were statistically significant differences among the three groups in age,sex,tumor location,presence or absence of false capsule,presence or absence of hemorrhage,the age distribution of onset,and degree of en-hancement(P<0.05).There was no significant difference in the size and shape,calcification,necrotic cystic change,enhancement mode,growth mode,invasion to tissues and metastasis signs of the tumor(P>0.05).Compared with CCRCC and PRCC,MiT RCC has a younger age of onset,is more common in women,has a higher incidence of bleeding,and is more likely to show intrarenal growth.The incidence of pseudocapsule was higher in MiT RCC and CCRCC than that of PRCC(P<0.05).The enhancement degree was CCRCC>MiT RCC>PRCC(P<0.01).Conclusion The ima-ging manifestations of MIT RCC have certain characteristics.It is helpful to improve the preoperative diagnosis rate in com-bination with children and young people under the age of 30 years,and the presence of masses in the renal contour with hemorrhage,calcification,false capsule,multiple lymph nodes and distant metastasis.
