CT and MRI features of testicular solid lesions / 中国医学影像技术

ABSTRACT

Objective To analyze the imaging features of testicular solid lesions.Methods The CT and MR findings of 18 cases of testicular solid lesions confirmed by pathology were retrospectively reviewed.The location,attenuation/signal,size,shape,edge,and enhancement patterns of lesions were analyzed.Results In all of the 18 cases,5 cases were seminomas,1 of them was huge with punctate calcification,4 of them had low signal separations in T2WI.Lymphomas were in 4 cases,and all of them were primary diffuse large B cell lymphoma;T2WI was priority with low signal.Solitary fibrous tumor was in 1 case,and the attenuation was lower than that of muscle.Embryo in sinus tumor were in 1 case,and the attenuation/signal was unhomogeneous;the continued enhancement liking grid was obviously seen after contrast injection.Nonspecific inflammatory masses were in 4 cases with involving epididymis in 2 cases,and the attenuation/signal was unhomogeneous.Tuberculous mass were in 3 cases,and 1 case with points of calcificationwas on the edge of lesion,2 cases characterized by short T2 signals.Conclusion It is possible to make an accurate diagnosis by the combination of clinical data with imaging features in most of the testicular solid lesions.
