Abstract:Background According to sick lobe theory, one or more lobes of the breast are more prone to the development of carcinoma. However, the implications of this theory in breast magnetic resonance imaging (MRI) are unknown. Purpose To evaluate the MRI appearance of mass type (multifocal and multicentric diseases) and non-mass type (non-mass enhancements) sick lobe patterns, together with the histopathology results. Material and Methods MRI reports of 2015 patients in two tertiary breast imaging centers between June… Show more
“…The main indications for breast MRI were to detect multifocal, multicentric or contralateral breast carcinomas; to reveal invasive components in ductal carcinomas in situ; to identify occult cancer in patients with metastatic axillary nodes; to detect unequivocal findings on conventional imaging, to follow-up of neoadjuvant chemotherapy, to evaluate breast implants, and postsurgical findings. [16][17][18][19][20] Breast MRIs: Breast MRIs were performed by a 3T system (Skyra; Siemens, Germany) with a dedicated breast coil in the prone position. The obtained sequences were sagittal fat-saturated turbo spin echo (TSE) T2-weighted imaging (WI), transverse short tau inversion recovery (STIR), transverse TSE T1-WI, transverse diffusion-WI using single-shot echoplanar imaging, transverse pre-and post-contrast fatsaturated fast low-angle shot (FLASH) 3D T1-WI.…”
Objective: The study aimed to assess the sternum's morphology and morphometry, and to find anomalies and diseases using breast magnetic resonance imaging (MRI).
Materials and Methods: Retrospective evaluations of 320 breast MRIs were conducted. Congenital abnormalities accompanying pathological conditions were investigated. The sternum overall’s length, the manubrium-corpus’ width and length, and the manubrium-corpus-xiphoid’s shape were all measured. The relationship between the manubriosternal fusion and age was analyzed.
Results: Pectus excavatum, sternal band, sternal foramen, angled sternum and the sternal band, rachitic rosary, intraosseous ganglion, sternoclavicular joint degeneration, sternoclavicular joint ganglion cyst and costal cartilage calcifications, breast carcinoma metastasis, enchondroma and invasion of costal cartilages by malignant mesenchymal tumour were determined. The average length of the sternum was 144±14 mm, the manubrium length is 46±6 mm and the corpus length is 89±10 mm for adults. Manubrium was most commonly trapezoid in shape, the corpus was longitudinal oval and xiphoid was flat. 67% had no manubriosternal fusion. The degree of manubriosternal fusion did not show statistically significant correlation with increasing age.
Conclusion: The sternum, sternoclavicular, and sternocostal joints are susceptible to a wide range of congenital abnormalities and clinical conditions. Age increase has no relation to manubriosternal fusion.
