Ileal duplication cyst associated with type-3 ileal atresia: report of a case.

We report the case of a neonate with an ileal duplication cyst and type-3 ileal atresia. Although various pathogenetic mechanisms have been suggested to explain the genesis of these separate entities, this case and others previously described lend support to the theory of "vascular pathogenesis" for both of these lesions. The relevant literature pertaining to the causation of these lesions is discussed.
