Imaging Diagnosis of Testicular Lymphoma in Young Male Patient: Incidental Finding in Ultrasonography

Abstract

BACKGROUND: Ultrasonography is a common diagnostic procedure in patients with testicular abnormalities. Primary testicular lymphoma (PTL) is rarely discovered and is more common among elderly populations. CASE PRESENTATION: This case describes a young male patient with a history of painless testicular enlargement. Ultrasonography reveals an incidental finding of hypoechoic echo structural mass and increased vascularity using color Doppler ultrasonography. The further pathological examination discovered the findings indicative of a non-Hodgkin, diffuse, and large B-cell lymphoma. These distinctive features should be helpful in suggesting a diagnosis of PTL on imaging. CONCLUSION: PTL is a rare and aggressive extranodal NHL. Despite its low incidence, it is an extremely rare testicular cancer at a young age. Careful ultrasound imaging examination should be applied in patients with testicular enlargement. The presence of hypoechoic echostructural and an increase in vascularity should be considered for the possibility of a diagnosis of primary testicular tumor.
