Association between age and pneumonia profiles in COVID-19 patients

This study aimed to determine the frequency of CT scan involvement due to COVID-19 pneumonia in different age groups of patients.

Patients with COVID-19 were referred to Amir al-Momenin Hospital in Arak City from May 2020 to June 2021. Age, sex, history of underlying disease, and CT scan results were recorded. CT scan Scores on the 5th to 8th day for patients were determined. The prepared CT scan was evaluated, and the pattern of pulmonary involvement and the prevalence of involvement in the lobes were assessed separately (upper, lower, peripheral, and bronchovascular fairytale).

Overall, 349 patients were included. The mean age was 50.89 years. The most common involvement of the right lower lobe was 92% and the left lower lobe was 89.1%. Most patients had peripheral lung involvement. The average number of lobes involved was 4.14. GGO and GGO and Consolidation were correlated with younger patients. Higher Consolidations were observed in the age groups of 30 to 50 and 50 to 70. Crazy Paving is more common in the elderly and Halo was more common in young patients. The severity of lung involvement and the number of lobes involved were associated with high age.

Different age groups have specific features in CT scans to assess COVID-19 patients. Crazy Paving Appearance, Subplural bands, GGO, and Consolidation were seen in the elderly and severe/critical patients. Also, the amount of involvement and the number of lobes involved in the lungs of patients increases in patients of high age.
