Resumo
Os autores apresentam os aspectos na tomografia computadorizada de alta resolução de um doente com hemorragia pulmonar difusa por leptospirose. O achado predominante consistiu de opacidades em vidro despolido difusas, com espessamento de septos interlobulares sobrepostos, resultando no padrão de crazy-paving. O doente morreu, e na necrópsia foi observada extensa hemorragia alveolar, com sangue infiltrando os septos interlobulares. É realçada a correlação entre os achados anatomopatológicos e na tomografia computadorizada de alta resolução.

Leptospirosis of the lung presenting with crazy-paving pattern: Correlation between the high-resolution CT and pathological findings
Abstract
The authors present the high-resolution CT findings of a patient with diffuse pulmonary hemorrhage due to leptospirosis. The main finding consisted of extensive ground-glass opacities super imposed on mild interlobular septal thickening, resulting in the appearance termed “crazy-paving”. The patient died and the necropsy showed extensive haemorrhage filling the airspace and blood infiltrating the interlobular septa. The correlation between the high-resolution CT and pathological findings is emphasised.
Key-words: Leptospirosis, pulmonary haemorrhage, crazy-paving pattern, high resolution CT.
