Left Arm Pain, Numbness, and Weakness

ANSWER
The radiograph shows no evidence of a fracture. However, there is a 2-cm focal sclerotic area noted within the juncture of the humeral neck and head. This finding could represent an enchondroma, a bone cyst, or a bone infarct. Additional imaging, including MRI and bone scan, is warranted, as is orthopedic evaluation. This finding is likely incidental, as the patient’s clinical exam is suggestive of a cervical radiculitis referable to the herniated disc in her neck.
