The CT scanogram demonstrates the unusual "cardiomegaly" per the initial chest X-ray.
Multiphasic CT imaging confirms a large anterior mediastinal and prevascular mass of predominantly fat density typically "hanging down" on either side of the pericardium to reach the diaphragms inferiorly. The sagittal and coronal reformats demonstrate the scale of the mass extending from the superior mediastinum to the diaphragm and retrosternal to the posteroinferior thorax. There is no appreciative capsule, no calcification, no fat-fluid levels
There is scattered inhomogeneous and serpiginous, soft tissue density, minimally enhancing tissue, representing thymic tissue.
There are no calcifications and no fat-fluid levels. There are no suspicious mediastinal or hilar lymph nodes. There is compressive atelectasis, the lungfields are otherwise normal.
There is an incidental lobulated left breast mass lesion with associated calcifications.
The CT scanogram and reformats allude to the elevated BMI and obesity.
There are no osseous or upper hepatic metastases.
There is a calcified intrabdominal mass not fully characterised on the CT chest.
