case_images: Initial chest computer tomography (CT) revealed bilateral peripheral calcified and non-calcified cavitary lesions that ranged from 0.4 to 0.9 cm (Figure 1).
case_images: Multiple bilateral nodules, the largest of which is 2.3 cm in the greatest dimension. Notably, the previously seen peripheral nodule has grown and is portraying a more prominent cavitary component.

case_images: Chest CT scan showed multiple new bilateral solid lung nodules, the largest of which was in the right lower lobe and measured 2.3 x 2.0 x 1.6 cm (Figure 2).
case_images: Histopathological observations of the lesion. (A) (40x) presents a broad overview of the lesion, with minimal adjacent lung tissue visible on the right. (B) (100x) reveals the existence of hyaline cartilage (star). (C) (200x) exhibits a close-up view of the lesion, showcasing a fibromyxoid background with structures resembling placental villi (arrow). (D) (100x) demonstrates the presence of trapped respiratory epithelium (arrowhead).

case_images: Computer tomography-guided core biopsy of the lesion revealed lung with a variable mixture of hyaline cartilage, entrapped respiratory epithelium, and fibromyxomatous stromal changes (Figure 3).
