MRI findings of primary testicular lymphoma

Objective :To explore MRI features of primary testicular lymphoma(PLT) in order to increase the awareness of it. Methods:The MRI and pathological data of 8 patients with PLT proved by histopathology after surgery were analyzed retrospectively. Results:Six cases were located in the unilateral testis,two cases in the bilateral testis. Five cases were oval or round-like and three cases were irregular lobulated in shape. All 8 cases invaded albuginea,five cases invaded tunica vaginalis and epididymis,two cases invaded spermatic cord. Concerning the pathological local stage,3 cases showed with T1 and T2 stage respectively,2 cases with T3 stage. Necrosis was found in two cases. The signal was isointense(1 case) or hypointense(7 cases) on T1WI and homogeneous hypointense(6 cases) or inhomogeneous hyperintense(2 cases) on T2WI. All cases showed hyperintense on DWI,hypointense on ADC. Three cases demonstrated mild contrast enhancement,one case showed delay enhancement,the TIC was plateau(type Ⅱ). Two cases displayed necrosis and no case showed hemorrhage. Conclusions :An accurate diagnosis of PLT is still hard to be made preoperatively. PLT is more common in elderly men,and MRI has certain characteristics,which is helpful for preoperative diagnosis.
