Radiological & clinical findings in sporadic cases hospitalized for H1N1 pneumonia

PurposeTo evaluate the CT and clinical findings in patients with H1N1 pneumonia and to discuss any differences between our results and previously reported articles.Patients and methodsScreening for cases was started in April 2015. First case was diagnosed in October 2015. The number of cases increased with Peak in December. We reviewed and analyzed the primary CT patterns and the clinical presentation.ResultsOur patients were more prevalence in the age ranges from 30 to 60 years, equally distributed in both sex. Cough & fever (94%) were the most frequent clinical presentation .The commonest CT finding was the patchy Ground-glass appearance (either alone or associated with other findings) found in 11 cases (69%) followed by Consolidation in 10 patients (63%). The lung affection was bilateral in 14 patients (88%), multifocal in 13 patients (81%), Peripheral location was in 10 patients (62%). Out of the 16 positive cases in CT scan, the X-ray showed positive findings in only 12 cases (75%).ConclusionsThe most common lung pattern in H1N1 was GGO and consolidation, with bilateral and multifocal involvement in the majority of cases showing peripheral tendency. X-ray missed about 25% of cases.
