In living donor lung transplant, donor lobectomies from 2 donors provide right and left lower lobes for transplantation. In the past, routine evaluation of pulmonary anatomy was not performed preoperatively. Intraoperatively, surgeons were often forced to sacrifice the lingular artery or right middle lobe segmental artery to obtain an adequate arterial cuff for safe reimplantation. This study was performed to evaluate the utility of preoperative 3D-multidetector CT angiography (3D-MDCTA) as a noninvasive method of assessing pulmonary arteries to improve donor selection and surgical planning for living lung donors. ⋯ Safely explanting lower lobes from living donors for lung transplantation poses challenges not encountered in harvesting cadaveric donors or performing lobectomies for malignancy. 3D-MDCTA of pulmonary arteries can noninvasively delineate the often-complex pulmonary anatomy, which may assist in donor selection as well as reduce donor intraoperative and postoperative vascular complications.

We report an extremely rare case of Behçet disease complicated by diffuse alveolar damage, which was fatal in this patient. It manifested as progressive diffuse ground-glass attenuation in both lungs on chest radiographs and high-resolution CT. Ground-glass attenuation was confirmed histopathologically as diffuse alveolar damage without identified etiology by open lung biopsy.

Traumatic pericardial rupture is a rare injury with potentially fatal consequences, usually occurring in patients who have sustained other severe injuries of the chest and abdomen. Diagnosis is difficult and is commonly made at the time of surgery. Radiographs and computed tomography of the chest may provide clues to the diagnosis. We present one case of left pleuropericardial rupture and another of traumatic diaphragmatic pericardial rupture.

Meningioma with extracranial metastases is a rare occurrence. However, the lungs are the most common site of extracranial metastases. We describe a case of a patient with recurrent intracranial meningioma and intrapulmonary metastases.

Case Reports
Multiple rheumatoid nodules with rapid thin-walled cavity formation producing pneumothorax.
We report a rare case of multiple rheumatoid nodules that on chest CT demonstrated peripheral location with thin-walled cavity formation, rapid increase in size within several months, and complicating pneumothorax, pneumomediastinum, and subcutaneous emphysema due to bronchopleural fistula formation.
