From: Ultrasound findings to predict failure of conservative treatment in the appendix testis torsion
Thirteen megahertz linear probe ultrasounds. Comparison between a testis affected by TAT (A–C) and the contralateral one (D). A Maximum diameter of the twisted hydatid is measured (white dashed line). B Hydrocele (white star) secondary to the twisted hydatid is registered. C Epididymitis, defined as an increase in volume, echogenicity, and blood flow of epididymis compared to the healthy contralateral side (D)
