case_images: Chest radiography: (a) preoperative chest radiograph demonstrated a mass shadow in the left upper and middle lung fields; (b) postoperative chest radiography on the day of surgery showed drains in the neck and chest wall abscesses (arrowheads) and the retrosternal and extrapleural abscesses (arrows).

case_images: Chest radiography showed a mass shadow in the left upper and middle lung fields (Figure 1(a)). Chest computed tomography (CT) revealed an enlarged left sternoclavicular joint; abscesses in the neck, chest wall, and retrosternal and extrapleural spaces (Figure 2); anterior mediastinitis (Figure 2); and osteomyelitis of the clavicle and sternum (Figure 3). After irrigation with saline solution, closed suction drains were placed in the abscess cavities and connected to a negative pressure system (SB VAC Super-Smooth, SB-Kawasumi Laboratories, Inc., Japan) (Figure 1(b)).
case_images: Contrast-enhanced chest computed tomography images in axial (a, b), sagittal (c), and coronal planes (d) on admission: (a) the infected joint enlarged the joint space (arrowhead); (b) the chest wall abscess was connected to the retrosternal abscess (arrowhead) and the extrapleural abscess via the first intercostal space (arrow); (c) the retrosternal abscess was complicated by anterior mediastinitis (arrowheads); (d) pyogenic arthritis of the sternoclavicular joint (arrowhead) involved the neck, chest wall, and extrapleural space.

case_images: Chest radiography showed a mass shadow in the left upper and middle lung fields (Figure 1(a)). Chest computed tomography (CT) revealed an enlarged left sternoclavicular joint; abscesses in the neck, chest wall, and retrosternal and extrapleural spaces (Figure 2); anterior mediastinitis (Figure 2); and osteomyelitis of the clavicle and sternum (Figure 3).
case_images: Contrast-enhanced chest computed tomography images in axial (a, b), sagittal (c), and coronal planes (d) four months after surgery.

case_images: Chest radiography showed a mass shadow in the left upper and middle lung fields (Figure 1(a)). Chest computed tomography (CT) revealed an enlarged left sternoclavicular joint; abscesses in the neck, chest wall, and retrosternal and extrapleural spaces (Figure 2); anterior mediastinitis (Figure 2); and osteomyelitis of the clavicle and sternum (Figure 3). The sternoclavicular joint infection was cured four months after surgery (Figure 3).
case_images: Chest computed tomography images with bone window: (a, f) on admission; (b, g) one week postoperatively; (c, h) two weeks postoperatively; (d, i) three weeks postoperatively; (e, j) four months postoperatively. Osteomyelitis (arrowhead) of the clavicle (a-e) and sternum (f-j) worsened within a few weeks after surgery but recovered within four months after surgery.
