Cystic formations of the lung in children

Twenty children are presented, aged 1 to 10 years, with cystic lung diseases (15 years period review). We have found (and pathohystologically confirmed) the following diagnoses: intrapulmonal inflammated cysts (in 12 patients), tensic cyst (in 2 patients), lung echinococcosis (in 2 patients), congenital lobar emphysema (in 2 patients), congenital adenomatoid malformation type I (in 1 patient) and congenital bronchiectasies (in 1 patient). The cystic formations were surgically removed. The cystic formations have to be treated surgically, because of possible complications-inflammation, rupture or malign alteration.
