Paralabral cysts of the shoulder are rare, and there are few reports available that describe anteroinferior paralabral cysts arising from a detached antero-inferior glenoid labral tear without shoulder instability. We report an antero-inferior labral tear without shoulder instability in adolescent overhead athlete associated with paralabral cyst that leads to axillary nerve neurapraxia. Although nonoperative management of such labral lesions may provide symptoms of relief, it may not be enough for the athlete to return to the game. However, surgical treatment in this case provides successful recovery and rapid return to playing baseball play without having to worry about the progression of muscle denervation.
