Large mixed density ovoid soft tissue density mass within the left anterior chest wall measures 126 x 127 mm in the axial plane (increased compared to 116 x 112 mm previously) and 105 mm in the coronal plane. It is centred on the anterior left 3rd rib with rib splaying evident. Destructive bony changes in the associated left anterior 2nd, 3rd and 4th ribs. There is a further expansile lesion in the lateral aspect of the left 3rd rib which is unchanged in size and appearance. No new bony lesions identified.
The chest wall mass exerts mass effect on the left ventricle. The heart, pericardium and great vessels are otherwise within normal limits. No lymphadenopathy within the thorax by CT size criteria. The lungs and pleura are clear.
Limited views of the upper abdomen are within normal limits.
IMPRESSION
Slight increase in the size of the left anterior chest wall pseudotumour as described above but not exceeding that of the prior CT.
