A case is reported in which computerized tomography (CT) was particularly helpful in anatomically localizing the lesion as well as in identifying an atypical nidus.

Case Report

An 8-year-old Hispanic boy presented at Children's Hospital, with a one-year history of pain in his right shoulder and neck that was worse at night and was partially relieved by aspirin.
