CT findings of PBL in the same patient. Images of the CT scan obtained with intravenous contrast media [coronal image on a mediastinum window (a); axial images on a mediastinum window (b, c), and axial image on a bone window (d)] demonstrate an extensive ulcerated lesion in the right breast with heterogenous contrast enhancement, extending to the ipsilateral axillary region. It presents multiloculated fluid collections (orange asterisk) and multiple gas bubbles. There is deep invasion of the chest wall, with infiltration of the muscular planes (pectoralis major, pectoralis minor and intercostal muscles) and cortical bone disruption of adjacent ribs (yellow circle), as well as associated pleural invasion (yellow asterisk). Small right pleural effusion can also be noted (yellow arrow)
