A confounding rib variation: bilateral symmetric aberrant posterior rib articulations and bridgings.

Introduction: Although mild bone angulation with osseous enlargement often suggests fractures with callus formation, in some cases the diagnosis is synchondrosis.

Case Report: We present a rare variation of the chest wall in a 15-year-old male with a history of lymphoma. Bilateral multi-level posterior rib enlargements revealing mild F-fluorodeoxyglucose uptake were detected via positron-emission tomography/computed tomography.
