Infraclavicular brachial plexopathy secondary to coracoid osteoid osteoma.

Coracoid osteoid osteomas are rare. This case report presents two patients with coracoid osteoid osteomas who developed neurologic sequelae of the infraclavicular brachial plexus (namely, musculocutaneous neuropathy in one patient with an anterior lesion, and suprascapular neuropathy in the other patient with a more posterior lesion). The neuropathy was due to soft tissue edema, which surrounded the bony lesion and was apparent on MRI. Surgical resection of the bony lesion in both cases produced excellent outcomes at long-term follow-up.
