Torsion of epididymis

A condition of the epididymis, caused by determinants arising during the antenatal period. This condition is characterised by twisting of the epididymis around its axis and ischaemia, scrotal pain, or inflammation. This condition may also present with a thickened scrotal wall, a reactive hydrocele, and enlargement of the head of the epididymis. Confirmation is by imaging.
