Abstract:

Objective: In this paper, we retrospectively analyzed the ultrasonographic features of paratesticular leiomyoma to help doctors correctly diagnose the disease before operation and guide surgical treatment.

Methods: From 2013 to 2020, 16 cases of paratesticular leiomyomas confirmed by pathology in our hospital were retrospectively analyzed. The retrospective analysis included the ultrasound and color Doppler flow imaging (CDFI) of paratesticular leiomyoma which were evaluated by two experienced radiologists based on the features of ultrasound images of lesions.

Results: All the 16 paratesticular leiomyoma presented as hypoechoic masses with a clear boundary and round shape. The echotexture of 6 large leiomyomas showed a typical vortex appearance. In the remaining 10 small leiomyomas, thin cord-like hyper-echogenic appearance was found. Color Doppler flow imaging showed that the blood flow signal within a large leiomyoma mass (n = 1) was significantly higher than that of surrounding testis while the blood flow signals of the smaller leiomyomas (n = 5) had significantly less flow signals compared with the testis. The remaining leiomyoma masses (n = 10) had similar flow signals to the testicular blood flow.

Conclusion: Sonography can be used to detect testicular tumors and to differentiate extratesticular from intratesticular masses. The ultrasound features of paratesticular leiomyoma included hypo- and hyperechoic mass, a round or typical vortex shape as well as various vascularity based on the size of the tumors.
