Computed tomography with three-dimensional reconstruction revealed a heterogeneous, cystic bony lesion limited to the manubrium sterni.

The cortices were eroded, and the maximum diameter of the lesion was 3 cm (Figure 1).
(A) Skin incision planning. (B) En-bloc resection of the manubrium sterni; upper part of the corpus sterni; first, second, and third bilateral parasternal ribs; and the medial clavicles, whose stumps were fixed on the first ribs. 1. Manubrium sterni tumor; 2. Second left rib; 3. Third left rib; 4. Mediastinal fat; 5. Right lung. (C) Musculocutaneous flaps covering chest wall reconstrauction.

The manubrium sterni was removed together with the upper part of the corpus sterni; its cutaneous covering; the medial first, second, and third bilateral parasternal ribs; and the medial clavicles to achieve a sufficient resection margin (Figure 2).
(A) Computed tomography revealed more narrowing at the level of the vein on the left side (5 mm) than the right side (11 mm). (B) Three-dimensional reconstruction indicating loss of contrast over the subclavian vein due to delayed opacification, secondary to stenosis.

The space at the level of the artery was symmetrical, with a 10 mm distance on both sides (Figures 3A,B).
