Intralobar pulmonary sequestration; with special emphasis on bronchial communication

The radiologic and pathologic features of eight cases of intralobar pulmonary sequestration are reported. Special attention was given the communication between the cystic areas and the normal bronchial tree. In three of five surgical specimens, probing revealed such communications. Microscopically, the transition from the normal bronchus to the cysts revealed no inflammation to suggest fistulous communication secondary to infection. The possibility of preexisting congenital bronchocystic communications within the pulmonary sequestrations was therefore suggested.
