Twenty percent of intradepartmental referrals to a tertiary medical center musculoskeletal radiology section involved osseous lesions of the rib. We aim to increase confidence, regardless of sub-specialty training, in the diagnostic workup of rib lesions. This exhibit offers:   A multimodality review of benign and malignant entities that involve the rib An algorithm that utilizes characteristic imaging features to aid in diagnostic workup, with particular attention paid to benign mimics of malignancy Examples of rib biopsies with procedural tips and technique  

Review of normal radiographic appearance of the rib and associated structures Entities presented include: Normal variants/Congenital: fused, bifid, extranumerary rib, rib notching Trauma: fractures (pathologic, healing, and stress), post-surgical presentations Neoplastic: primary malignancy (multiple myeloma, Ewing’s sarcoma, lymphoma, chondrosarcoma) and metastatic (blastic vs lytic) Benign: enchondromas, bone island, fibrous lesions (non-ossifying fibroma and fibrous dysplasia), aneurysmal bone cyst Metabolic/Systemic: hyperparathyroidism, osteomalacia, osteopetrosis, Paget’s, sickle cell disease, eosinophilic granuloma Management algorithm Rib biopsy technique and points to consider
