[Bilateral multilobular cystic adenomatoid malformation].

We reported a case of bilateral and multilobar Congenital Cystic Adenomatoid Malformation (C.C.A.M.) in a four months old child with good clinical results after resections of the lesions. This is a relatively rare form of pulmonary illness. The final prognosis, in those patients, depends on the type of malformation, the presence or absence of fetal hydrops and on the degree of affected lung. There have been reported a few cases of multiple affectation. We will consider the physiopathological aspects of the case, late clinical presentation and treatment and the positive surgical response based in the findings of the functional and anatomic imagen studys.
