The purpose of this series was to describe the sonographic findings of tuberculous vasitis. We conducted a retrospective analysis of 3 cases of tuberculous vasitis. The following grayscale and color Doppler sonographic features were analyzed: location, echogenicity of the lesion, epididymal or testicular involvement, presence of hydrocele, and blood flow within the lesion. All 3 patients had focal (n = 2) or multifocal (n = 1) involvement of the scrotal segment of the vas deferens. The sonographic findings for tuberculous vasitis were heterogeneously hypoechoic in all of the cases. On color Doppler sonography, no blood flow was identified within the lesions of the vas deferens. All 3 patients had tuberculous epididymitis in addition to tuberculous vasitis. Tuberculous vasitis presents with infection along with tuberculous epididymitis, and it appears as a heterogeneously hypoechoic lesion in the scrotal segment of the vas deferens adjacent to the epididymal tail.
