Abstract
in English, Portuguese

Objective: To evaluate computed tomography (CT) findings in 23 patients with bronchial atresia.

Materials and methods: The CT images were reviewed by two radiologists who reached decisions by consensus. We included only patients who presented with abnormalities on CT and in whom the diagnosis had been confirmed by pathological examination of the surgical specimen (if the lesion was resected). The CT scans were assessed in order to identify the main findings and to map the distribution of the lesions (i.e., to determine whether the pulmonary involvement was unilateral or bilateral).

Results: The main CT finding was the combination of bronchocele and hyperinflation of the distal lung. That combination was observed in all of the patients. The lesions were unilateral in all 23 cases, being seen predominantly in the left upper lobe, followed by the right lower lobe, right upper lobe, middle lobe, and left lower lobe.

Conclusion: The diagnosis of bronchial atresia can be reliably made on the basis of a finding of bronchocele accompanied by hyperinflation of the adjacent lung parenchyma.

Objetivo: Analisar os achados na tomografia computadorizada (TC) de tórax de 23 pacientes com atresia brônquica.

Materiais e métodos: As imagens de TC foram avaliadas por dois observadores e os casos discordantes foram resolvidos por consenso. Os critérios de inclusão foram a presença de anormalidades na TC compatíveis com atresia brônquica e/ou diagnóstico confirmado por exame anatomopatológico das peças cirúrgicas para os pacientes submetidos a ressecção cirúrgica. As TCs foram avaliadas quanto aos principais achados de imagem, à distribuição das lesões, ao envolvimento pulmonar unilateral ou bilateral.

Resultados: Os principais achados na TC foram a presença de broncocele, hiperinsuflação do parênquima pulmonar ou ambos. A combinação desses achados foi encontrada em todos os pacientes. Em relação à distribuição, o envolvimento foi unilateral nos 23 casos. Quando se consideraram os lobos mais acometidos, o lobo superior esquerdo foi o mais acometido, seguido do lobo inferior direito, lobo superior direito, lobo médio e lobo inferior esquerdo.

Conclusão: O diagnóstico de atresia brônquica pode ser feito em presença de broncocele associada com hiperinsuflação do parênquima pulmonar adjacente.

Keywords: Bronchi/abnormalities; Congenital abnormalities; Tomography, X-ray computed.

Female, 28-year-old, asymptomatic. Axial chest CT scan with lung window settings, at the level of the pulmonary bases during inspiration (A) and expiration (B), together with a coronal slice acquired during expiration (C), showing a lobulated nodule (mucocele), in the posterior basal segment of the right lower lobe, with an area of hyperinflation around the lesion (air trapping), best visualized in the expiratory sequences (B,C).
