Magnetic Resonance Imaging Findings of Anatomy, Variation and Pathologies of Sternum, Sternoclavicular and Sternocostal Joints

Objective: The study aimed to assess the sternum's morphology and morphometry, find anomalies diseases using breast magnetic resonance imaging (MRI).
 Materials Methods: Retrospective evaluations of 320 MRIs were conducted. Congenital abnormalities accompanying pathological conditions investigated. sternum overall’s length, manubrium-corpus’ width manubrium-corpus-xiphoid’s shape all measured. relationship between manubriosternal fusion age was analyzed.
 Results: Pectus excavatum, sternal band, foramen, angled rachitic rosary, intraosseous ganglion, sternoclavicular joint degeneration, ganglion cyst costal cartilage calcifications, carcinoma metastasis, enchondroma invasion cartilages by malignant mesenchymal tumour determined. average length 144±14 mm, manubrium is 46±6 mm corpus 89±10 for adults. Manubrium most commonly trapezoid in shape, longitudinal oval xiphoid flat. 67% had no fusion. degree did not show statistically significant correlation with increasing age.
 Conclusion: sternum, sternoclavicular, sternocostal joints are susceptible a wide range congenital clinical conditions. Age increase has relation
