Axillary Intraneural Ganglion Cysts
$25.00
Aside from affecting the stability of the glenohumeral joint, tears in the joint capsule can give rise to extraneural (paralabral) and, very rarely, intraneural ganglion cysts. This report presents the first two cases of axillary intraneural ganglion cysts in the literature with magnetic resonance imaging. Both cases were incidentally noted to have coexisting lesions (lymphadenopathy from an undifferentiated malignancy and suprascapular nerve entrapment, respectively). This report reinforces the applicability of the articular theory for intraneural ganglion cysts at a novel site.
