Summary  Following the implementation in Uruguay of pneumococcal conjugate vaccines (PCV), there was a decrease in hospitalizations for bacterial community acquired pneumonia (CAP) at Hospital Pediátrico del Centro Hospitalario Pereira Rossell (HP-CHPR). Also, in recent years there were assisted children who developed necrotizing pneumonia (NP). NP are called CAP cases where inflammation determines ischemia and necrosis of the parenchyma with pneumatoceles formation and bronchopleural fistula when it occurs in the periphery lung. They are serious patients with poor general condition, persistent fever and require prolonged hospitalization. The pneumatoceles are diagnosed on radiography and/or chest computed tomography. We performed the description of hospitalized children with CAP in the HP-CHPR, which evolved NN in 2010. Twenty-eight children were diagnosed with an average age of 36 months, most healthy and eutrophic. Pneumatoceles were identified on chest radiography in almost all patients. They presented on average seven days of fever. Most developed pulmonary and/or extrapulmonary complications. Ten children required admission to intensive care unit. Hospitalizations lasted up to 43 days. No patient died. In half of the cases Streptococcus pneumoniae was identified. All isolates were sensitive to penicillin. None of the patients with PCV serotypes was adequately immunized. NN is a serious complication of CAP, which occurs in healthy children. Determines prolonged hospitalization and high morbidity. It is important to maintain surveillance of hospital admissions for CAP and its complications after universal vaccination with PCV.
