Objective
To discuss the diagnostic and differential diagnostic value of ultrasonography for primary testicular lymphoma (PTL) by studying the ultrasonographical image characteristics.
Methods
Thirty-one patients with PTL confirmed by postoperative histopathology between 2005 and 2015 were chosen to be the study subjects. We retrospectively analyzed their ultrasonographical features and clinical data.
Results
Most PTL patients were elderly men, and the initial symptom was mainly painless testis enlargement. Thirty-nine testicles were involved in the primary testicular lymphoma, including 23 unilateral and 8 bilateral. In the 31 patients, 22 had diffuse lesions and 9 nodal. Ultrasonography showed that most tumors were hypoechoic lesions, and part of them were hyperechoic linearly. The lesions had abundant blood flow signals with a low resistance index.
Conclusions
In elderly patients with painless testicular enlargement, the possibility of primary testicular lymphoma must be fist considered. Manifestations of primary testicular lymphoma have some distinctive characteristics, and combined with clinical history, they are helpful for the diagnosis and differential diagnosis of PTL.
