The ultrasonic appearances of primary testicular lymphoma / 中华超声影像学杂志

ABSTRACT

Objective To explore the sonographic features of primary testicular lymphoma(PLT).Methods The sonographic features of 16 PLT patients confirmed by surgery and pathology were retrospectively analyzed.Results Sixteen PLT patients were typed into 3 ultrasonic patterns①The diffuse homogeneous echo type2 cases,the ultrasonic features were homogeneous sieve-like hypoechoic echo,the blood flow signal was rich and radially distributed,with interstisial fibrosis inapparently under-microscope.②The diffuse uneven homogeneous echo type9 cases,the ultrasonic features lobulated or map-like heterogeneous hypoechoic features,the blood flow signal was rich in linear distribution,and interstisial fibrosis proliferated to form fibrous septa under-microscope.③The focal nodular pattern echo type5 cases,the ultrasonic features were homogeneous hypoechoic nodules,the blood flow signal was few,interstisial fibrosis hyperplasia surrounding the tumor under-microscope.Conclusions Ultrasonic appearances of primary testicular lymphoma are closely related to its pathologic characteristics,the recognization of their relations contributes to improve the diagnostic value of ultrasound.
