چکیده
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.

The hantavirus pulmonary syndrome (HPS) is an acute, rapidly progressive disease transmitted by rodent excreta, with endothelial damage playing a central role in the pathophysiology. It usually affects rural workers. The lung itself is the target organ and reflects all the patterns of endothelial involvement of this disease. The radiologic findings of HPS are vast and range from a mild intersti...

Dr.Mirsadraei and colleagues performed an interesting study about the lung HRCT findings in chemical warfare patients who suffering from long-term pulmonary complications. They found that air trapping and mosaic attenuation were the most common lung HRCT findings. Also they divided patients in different clinical entities according to the lung HRCT findings (Bronchiolitis Oblitrans, pulmonary fi...
