Computed tomography of the thorax and abdomen (CT Thx/Abd) in 2018. There is a large, partially calcified soft tissue structure of the right breast with central hypodensity and possibly mucinous parts. The image shows infiltration of the thoracic wall and transfer to the mediastinum, with destruction of the corpus and manubrium sterni and infiltration of the musculus pecotralis major and the musculus serratus anterior on the right. Additionally, destruction of the adjacent medial clavicle on the right and of the first rib medial on the right was observed. The formation directly infiltrates the mediastinum, with infiltration of the pericardium and direct contact with the aortic arch. The maximum extent of this conglomerate was 25.2 × 14.8 × 10.0 cm (VU 22.7 × 16.6 cm axial; not fully recorded cranially). There was no flow obstruction of the right-side vessels of the upper thoracic aperture.
