CT scan showed no bulla, but revealed multiple small polygonal lesions consistent with fibrotic lesions mainly in the right lower lobe (figure 1).
In the centre of the photo, a drumstick-shaped bony solid tissue arose from inside the lung, and pierced the visceral pleura. Air leakage from the tear could be found during the operation. Irregular yellowish lesions under the pleura were dominant in the lower lobe (black arrows). (B) Microscopic view of the drumstick. Trabeculated mature bone structure with normal marrow was observed.

We performed right thoracotomy and found that air leakage arose from torn visceral pleura which had been pierced by a drumstick-shaped bony structure (figure 2A). Pathological exam revealed that this was mature bone with normal marrow (figure 2B).
