Malformation lung cystic adenomatoidea

Introduction: Cystic adenomatoid malformation is an alteration of lung development caused by the replacement of the small airway and lung parenchyma by cysts. Objective: Describe a case with a diagnosis of cystic adenomatoid malformation. Case presentation: 16-year-old male adolescent, product of a pregnancy with low obstetric risk, normal delivery at 38.4 weeks, with a personal pathological history of bronchial asthma, surgery for glaucoma at age 13, surgery for umbilical hernia at 12 years old, no history of previous income. On this occasion he went to the emergency room due to having a dry, sporadic cough that had been going on for approximately 15 days. In addition to sometimes presenting pain in the tip of the side, an X-ray was performed, confirming a radiopaque image in the left lower lobe, deciding to admit him for better study and treatment. Conclusions: Cystic adenomatoid malformation is a rare anomaly, so it is important to keep in mind that any patient with symptoms and signs suggestive of this disease receives complete care to guarantee an early diagnosis. The role of radiological diagnosis is key to fully characterize MCPs. The characterization of the vascular contributions in the radiological report is of great importance for surgical planning.
