Abstract:
Objective: To investigate the MRI manifestations of primary testicular lymphoma (PTL). Methods: Clinical and MRI data of 8 patients with pathologically confirmed PTL were retrospectively analyzed. Results: Plain MRI showed morphological abnormalities of affected testis in all 8 cases, and the volume increased. The lesions appeared as masses with clear borders, present low signals on T1WI in all 8 cases and spot-like high signals in 3 cases, uneven iso-low signals on T2WI showed. Epididymis and spermatic cord involvement were found in 3 cases, the boundary of testis and epididymis were not clear, and signals were heterogeneous, spermatic cord with multiple curved strips of high signal on T2WI. Hydrocele occurred in 3 cases, including 1 case involved epididymis and spermatic cord. Obviously heterogeneous enhancement of lesions was found during delayed enhancement scanning, and unenhanced areas were noticed in 3 cases. The time-intensity curves (TIC) of lesions presented outflow type (type III) in all 8 cases. On DWI, the solid parts of lesions showed high signal, which showed low signal on ADC map in all 8 cases. Conclusion: MRI manifestations of PTL had certain characteristics. Combination of plain and dynamic enhancement MR were helpful to correct diagnosis of PTL.
