Bilateral Choanal Atresia in an Adolescent Female: A Rare Case Report.

Choanal atresia is a rare congenital anomaly of the nasal cavities characterized by lack of patency of the posterior ends of one or both nasal cavities (choanae). It is the most common congenital anomaly of the nasal cavity. Bilateral choanal atresia accounts for a third of the cases and is almost invariably detected in the neonatal age due to respiratory distress.

Bilateral congenital lobar overinflation (CLO) - a rare presentation of an uncommon condition.

Congenital lobar overinflation (CLO) is a rare congenital pulmonary abnormality characterized by progressive overexpansion of a lobe(s) exerting mass effect on the remaining lobes and the mediastinum. Bilateral involvement is extremely rare and has been reported only a handful of times. We present a case of bilateral congenital lobar overinflation in a term female neonate managed with single-step bilateral lobectomies.
