Chest MRI and CT findings of PBL in the same patient, complicated with bronchopleural cutaneous fistula. Chest MRI [(a) coronal and (b) axial T2-weighted images] and chest CT scan [(c) coronal and (d) axial images on a lung window]. MRI images show the extensive ulcerated lesion in the right breast with heterogenous signal intensity, extending to the ipsilateral axilla and deeply invading the chest wall, associated with pleural thickening (yellow asterisk). A fistulous tract filled with gas can also be seen (orange arrow), communicating with a peripheral bronchus of the right lung (yellow arrow) and extending into the pleural space and into the chest wall, traversing the breast lesion—it corresponds to a bronchopleural cutaneous fistula
