Findings and procedure details
This study were included 6 patients aged from 21 to 78 yo with confirmed H1N1 infection (by real time reverse transcriptase polymerase raection technique).
Chest CT examinations were performed all patients in emergency department of City Clinical Hospital №4 of Department of Healthcare of Moscow.
All patients were in severe condition and they were admitted to the intensive care unit.
During the initial CT study there was found:
- bilateral subpleural multifocal consolidation (2 cases) (Fig.
1);
- unilateral ground-glass attenuation (unique findings in 1 cases) (Fig.
2);
- bilateral peribronchogenic and subpleural ground-glass attenuation (1 cases) (Fig.
3);
- bilateral multifocal nodular opacities with "tree-in-bud" symptom (1 cases) (Fig.
4);
- no high attenuation pattern (1 cases).
There was no pleural effusion and mediastinal lymphadenopathy.
In the last case high attenuation pattern wasn't found,
however subpleural and centrilobular bullas and single calcifications were determined in the upper lobes of both lungs.
Сhanges in the lungs may not be manifested шт this patient because of early CT.
This study is not statistically significant because of the small number of patients,
but the swine flu outbreak occur periodically and it is necessary to remember about the possible changes in this pathology.
