| Summary: | Introduction: The first cases of H1N1 Influenza A occurred
in Mexico in 2009, thereafter the infection rapidly spread
worldwide. Seasonal epidemics and unpredictable pandemics
had been declared by the World Health Organisation (WHO),
since then.
Aim: To describe the Thoracic Multi-Detector Computed
Tomography (MDCT) findings in moderate to severely ill, H1N1
patients during epidemic spread.
Materials and Methods: A retrospective observational study was
done in which evaluation of 155 hospitalised patients confirmed
to have H1N1 Influenza A epidemic infection between October
2018-December 2018, through the radiologic and clinical aspects.
About 56 moderate to severely ill patients, who failed to improve
with through treatment, underwent thoracic cross-sectional MDCT
and their scans available on picture archiving and communication
system (PACS) were assessed and radiological findings were
evaluated with respect to clinical condition. Descriptive statistics
were used for representation of data.
Results: About 56 moderate to severely ill H1N1 patients who
underwent chest MDCT, consisted of 30 males and 26 females
ranging in age from 20 to 86 years with median age of 55.19
years. Ground glass opacities was found in 34 (60.71%) patients,
Consolidation in 33 (58.93%) patients, combined Ground glass
pattern and Consolidation in 18 (32.14%) patients and Acinar
nodules in 21 (37.50%) patients. Combined Peripheral & Central
distribution of lesions was found in 47 (83.92%) patients and
central lesions in 6 (10.71%) patients. The lesions were multifocal
in 51 (91.07%) patients and diffuse in 25 (44.64 %) patients.
Lesions seen in bilateral all lobes in 25 (44.6%) patients and
unilateral in 7 (12.5%) patients. Small mediastinal Lymphnodes
were detected in 42 (75%) patients, pleural effusion was
associated in 18 (32.14%) patients and pericardial effusion in
4 (7.14%) patients. In nonvulnerable group, 53 (94.6%) patients
showed full recovery as in those patients therapy was started
earlier while in vulnerable group 3 (5.35%) died immediately
after infection.
Conclusion: Unilateral or bilateral ground-glass opacities may or
may not be linked with focal or multifocal areas of consolidation
in the peribronchovascular and subpleural distribution that
resembled the appearance of organising pneumonia is the main
finding which was observed. |
