Learning objectives
To rewiew the radiological findings in patients with H1N1 infection (Swine-origin) in winter season 2016.
Background
The last pandemic of H1N1 infection (Swine-origin) was in 2009 [1].
The main characteristics of this virus are in a high incidence of infection,
which differs from those of seasonal influenza infections.
The clinical manifestations of this disease are various: from asymptomatic forms,
mild involvement of the upper airways (dyspnea,
fever,
coughing) and gastrointestinal system (diarrhea and nausea),
to severe pneumonia with acute respiratory distress syndrome,
sepsis and even death [2,3].
The diagnosis of H1N1 infection is usually suspected basing on clinical and radiological data,...
Findings and procedure details
This study were included 6patients 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);...
Conclusion
CT signs are not specific in the cases of H1N1 infection.
Even the absence of changes does not exclude the presence of this pathology.
