Simultaneous discovery of bilateral intralobar and extralobar pulmonary sequestrations.

We describe the rare case of bilateral bronchopulmonary sequestrations, one intralobar and one extralobar, in a 22-year-old man. The coexistence of two forms of separated sequestrations with a common vascularization support the theory that intralobar as well as extralobar sequestrations are congenital malformations.
