EXTRALOBAR PULMONARY SEQUESTRATION PRESENTING AS AN ANTERIOR MEDIASTINAL TUMOR IN AN ADULT

Extralobar pulmonary sequestration (EPS) is a rather uncommon congenit al anomaly. Most patients are diagnosed in their early life or during the first decade because of the early appearance of symptoms, includin g feeding difficulty, cyanosis, and dyspnea, or because of symptoms ar ising from the associated congenital abnormalities. Extralobar pulmona ry sequestration is more often found between the lower lobe and the di aphragm and is usually associated with other congenital abnormalities, but the case reported herein differs in these respects. In this repor t, an incidental finding of EPS is described in a 30-year-old Chinese man, where EPS presents as an anterior mediastinal mass roentgenograph ically. The mass was attached to the right suprahilar region by a fibr ovascular pedicle which contained a small elastic artery, veins, and n erve bundles.
