Abstract:
Objective: To observe features of tuberculosis in epididymis and testis on plain MRI, diffusion weighted imaging (DWI) and dynamic contrast enhanced (DCE). Methods: MRI features of 15 patients with epididymal and testicular tuberculosis (case group) confirmed by pathology and 20 normal testes of 10 patients with other diseases (control group) were retrospectively analyzed. Results: Among case group, 2 cases were unilateral epididymis tuberculosis, 11 cases were unilateral epididymis and testicular tuberculosis, 1 case was bilateral epididymis tuberculosis involving bilateral vas deferens, seminal vesicle gland and prostate, and 1 case was bilateral epididymis and testicular tuberculosis involving prostate. Epididymal and testicular lesions present as low mixed signal on T1WI, with few spot shape high signal, and the signal intensity was equal, whereas as high and slightly low signal on T2WI. The lesions were slightly high or ring-like high signal on DWI, with decreased ADC values. DCE showed inhomogeneous enhancement, and the ring enhancement characteristics became more obvious with time going. Thickening wall and enhancement of ductus deferens, non-enhanced patchy in prostate and multiple ringlike enhancement in seminal vesicle were also observed on DCE. Conclusion: MRI could be used to accurately assess epididymal and testicular tuberculosis involved organs of generation. DWI and DCE had high diagnostic value for tuberculosis in epididymis and testis.
