A Morgagni hernia is a congenital herniation of abdominal contents into the thoracic cavity through a retrosternal diaphragmatic defect. The reported incidence of congenital diaphragmatic hernias is estimated to be 1 in between 2000 to 5000 births. Morgagni hernias comprise 2% of diaphragmatic hernias. ⋯ In conclusion, a Morgagni hernia may cause intestinal obstruction. Routine radiographic studies are usually sufficient to arrive at the diagnosis, but a CT scan and sonography may be necessary. Laparotomy is appropriate for the management of symptomatic adult patients with Morgagni hernias, particularly those with findings of intestinal strangulation, with laparoscopic treatment an alternative approach in selected cases.

In the case presented here, FDG-PET was performed to evaluate the possibility of malignancy. High FDG accumulation, with a standardized uptake ratio (SUR) of 3.0, was noted in an upper nodular compartment of the mass that exhibited malignant features histopathologically. It was suggested that FDG-PET is helpful to know which parts of lesions are benign or malignant in patients with LFTP whose prognoses are usually difficult to predict.

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.
