Adductor Longus - Groin Pain in


Axial T1: Notice the Adductor Longus Tendon slightly thickened on the right side	Axial T1 slightly above the previous scan shows an osseous excrescence at the enthesis.

Comments

There a number of causes to account for groin pain in athletes, which include symphisis pubis instability or osteitis pubis, athlete's hernia, rectus abdominis tendinopathy, and adductor longus tendinopathy.

The case above illustrates a chronic injury to the right adductor longus after a skiing injury. Injuries at the enthesis tend to heal poorly and are prone to osseous hypertropy at the site of the initial injury. In our case, the osseous excrescence resulting from the injury shows signal changes on STIR, which correlate with the persistent symptomatology.
