Lesões do nervo ciático são causas comuns de dor e de limitação no membro inferior. Em razão da sua anatomia particular e do seu longo
trajeto, o nervo ciático é frequentemente envolvido em doenças da pelve e do membro inferior. Nos últimos anos, a neurografia por
ressonância magnética tem se firmado como ferramenta importante para o estudo de nervos periféricos, podendo ser amplamente
empregada para o estudo do nervo ciático. Para este fim, o conhecimento detalhado de sua anatomia e das principais doenças envolvidas
é fundamental para maximizar o desempenho diagnóstico por imagem.

Objective: The purpose of this study was to describe the high-resolution computed tomography (HRCT) findings in patients with hantavirus
pulmonary syndrome (HPS).
Materials and Methods: We retrospectively reviewed HRCT findings from eight cases of HPS. All patients were men, aged 19–70 (mean,
41.7) years. Diagnoses were established by serological test (enzyme-linked immunosorbent assay) in all patients. Two chest radiologists
analyzed the images and reached decisions by consensus.
Results: The predominant HRCT findings were ground-glass opacities (GGOs) and smooth inter- and intralobular septal thickening, found
in all eight cases; however, the crazy-paving pattern was found in only three cases. Pleural effusion and peribronchovascular thickening
were observed in five patients. The abnormalities were bilateral in all patients.
Conclusion: The predominant HRCT findings in patients with HPS were GGOs and smooth inter- and intralobular septal thickening, which
probably correlate with the histopathologic findings of pulmonary edema.
