[Cystic adenomatoid malformation pulmonary: are we able to foresee its evolution?].

The congenital pulmonary malformation are a rare entity in pediatric age. Between of them, the cystic adenomatoid malformation (MAQ) is the most ferquent entity, followed by pulmonary sequestration (SP) and the most rare broncogenic cyst. As a consequence of ultrasound and fetal magnetic resonance we are abble to diagnose earlier this patology. To know the clinical findings, the diagnosis, and the evolution, we have done a retrospective study of underwented MAQ at our hospital during the last 17 years, including such with late diagnosis as with prenatal diagnosis, and describing those presenting impredictable evolution or a different difficul diagnosis. We report four MAQ's cases. Three of them, about late diagnose: the first one evolutioned till malignant tumor, the second one with a supplementary lobe and third one with a wrong MAQ diagnose. The fourth one associated MAQ with a SP.
