case_images: Chest computed tomography. (A) Sagittal view showing the formation of a hematoma measuring approximately 19 x 8 cm. (B) Axial view showing a newly formed 13 x 10 cm hematoma in the right upper anterior chest wall without evidence of active bleeding or pseudoaneurysm.

case_images: Chest computed tomography (CT) angiography revealed a newly formed 18.7 x 13.1 x 9.6 cm hematoma in the right upper anterior chest wall, with no signs of active bleeding or evidence of a pseudoaneurysm or malignant tumor (Figure 1 and Figure 2).
case_images: Chest computed tomography angiography. (A) A coronal view shows intact vessel patency in the subclavian artery and axillary artery (red arrow), which could have contributed to the hematoma in the chest wall. (B) No extravasation or abnormalities were observed in the thoracoacromial artery (red arrow). (C) No abnormalities were observed in the main pedicle of the lateral thoracic artery (red arrow).

case_images: Bleeding was identified from a branch of the lateral thoracic artery within the deep portion of the pectoralis major muscle, as observed on CT angiography (Figure 3).
case_images: Intraoperative photographs. (A) Preoperative photograph. The patient presented with a painful mass-like lesion on the right side of the chest, without any bruising. (B) Postoperative photograph. Hematoma removal and vessel ligation were performed, followed by irrigation, placement of a closed suction drain, and primary closure.
