(A) Photograph of the anterior chest wall (arrow) consistent with bronchopleurocutaneous fistula with scar from a previous mastectomy evident (dashed arrow).

(B-F) Axial CT images of the chest from 2019, at the level of the aortic arch (C) and pulmonary trunk (D), show the area of cavitation in left upper lobe (arrow). Axial CT images from 2022 show progression of the left upper lobe cavity at similar anatomical levels (E and F), and coronal image (B) reveals evidence of a fistula through the anterior chest wall and communication with overlying skin (arrow).
