Diagnostic Workup
Imaging
Doppler ultrasonography of the testis: signs for torsion of testicular appendage are a mild hydrocele and an enlarged testicular appendix [fig. ultrasonography of hydatid torsion ] and evidence of testicular blood flow. The reliable differentiation between testicular torsion and torsion of the testicular appendage can be difficult; surgical exploration may be necessary.

Treatment of Hydatid torsion
In principle, the torsion of testicular appendage is treated conservatively with analgesics. In the case of surgical exploration, the testicular appendage is removed after coagulation of the basis.
