Congenital bronchiolar cysts simulating intralobar sequestration

Abstract

In a case of bronchiolar cysts simulating intralobar sequestration in a 9 month old infant, the main cyst occupied the right posterior basal segment, was attached to the diaphragm by a band containing an anomalous vessel, but had an unusual communication with the lower lobe bronchus. The history of the patient was characterized by repeated respiratory infections. The treatment consisted of a right lower lobectomy. The rarity of this malformation in infants under the age of 1 year is evident on review of the literature.
