چکیده

Two cases of extralobar pulmonary sequestrations from a walrus (Odobenus rosmarus) and a Steller sea lion (Eumetopias jubatus) are described in the present study. Grossly, an independent, soft unilocular cystic mass was found within the abdominal cavities of both animals, adherent to the diaphragm in O. rosmarus and attached to the cardia of the stomach in E. jubatus. Histopathologically, the cysts were lined by pseudostratified ciliated columnar epithelium with abundant goblet cells, while the wall comprised of glands, hyaline cartilage, bronchiole- and alveolus-like structures, smooth muscles, and large, well-developed elastic and muscular arteries. The pinniped cases presented are exceptionally rare and to the best of the authors' knowledge, marks the first descriptions of this congenital anomaly in wildlife.

Intradiaphragmatic extralobar pulmonary sequestration in adult

Extralobar pulmonary sequestrations may be located in intrathoracic or extrathoracic areas. Extrathoracic intradiaphragmatic extralobar pulmonary sequestrations are an extremely rare subset of bronchopulmonary sequestrations and there have been very few reported cases until now. We describe a 48-year-old Korean woman found to have left peridiaphragmatic lesion on computed tomography. We perform...

Extralobar pulmonary sequestration as a cause of recurrent pulmonary hemorrhage in a neonate.

Pulmonary sequestration is acystic or solid congenital lung malformation comprised of non functional lung tissue that does not communicate with the normal tracheobronchial tree and has a systemic arterial blood supply. There are two forms of sequestration: intralobar and extralobar. Its treatment is surgical resection. Here we presented a case of premature neonate with extralobar pulmonary sequ...
