Resumo
O termo bronquiectasia é definido como uma dilatação brônquica anormal persistente geralmente associada a inflamação na via aérea e no parênquima pulmonar. A doença continua a ser uma causa comum de morbidade e mortalidade, especialmente quando associada a doenças hereditárias, como a fibrose cística, a discinesia ciliar e a alguns estados de imunodeficiência. A tomografia computadorizada é, actualmente, a modalidade de escolha para o dianóstico e pode também contribuir para o manejo clínico, sugerindo possíveis diagnósticos. Destacamos nesta revisão a classificação, a fisiopatologia e as manifestações radiológicas desta doença.

Abstract
Bronchiectasis is defined as an abnormal persistent bronchial dilatation usualy associated with inflammation in the bronchial tree and lung parenchyma. The disease remains a common cause of significant morbidity and mortality, especially when associated with hereditary disorders such as cystic fibrosis, ciliary dyskinesia, and immunodeficiency states. Computed tomography is now the diagnostic modality of choice and may also contribute to clinical management, suggesting some etiologic causes. We highlight developments in classification, physiopathology and radiology of this debilitating disease.
