Clinical Features and CT Imaging Findings of Melioidosis Pneumonia
To summarize and analyze the clinical features and CT imaging findings of melioidosis pneumonia in order to increase awareness of this disease.
Methods
2
A retrospective study was done on clinical and CT imaging data of 68 cases with melioidosis pneumonia diagnosed from January 1, 2012 to April 1, 2023.
Results
2
Of the 68 cases, 62 presented with acute infection and 6 chronic infection, 88.2% were male, 85.3% were native residents of Hainan, 85.3% were farmers, 77.9% had onset in summer and autumn, 66.2% had diabetes, 100% had fever as the first clinical symptom, and 88.2% were confirmed positive by blood culture. In most patients, white blood cell count, neutrophil ratio, C-reactive protein and calcitonin levels increased, while lymphocyte ratio decreased, but no statistical difference was found between acute and chronic infection groups (
P
>
0.05). Of the patients, 36.8% recovered, 42.6% got better, 11.8% patients became therapy-resistant and 8.8% died. CT image showed pathomorphological changes including nodules/masses, patchy ground-glass attenuation or large patchy consolidation or all of these at the same time. Acute and chronic infection groups had significant difference in pathomorphological changes (
P
= 0.01), but no statistical difference in other imaging findings. Moreover, 36.8% of the patients developed extrapulmonary infections, 8.8% of which multi-site abscess formation.
Conclusions
2
Melioidosis Pneumonia should be considered if the patient is the sojourner from epidemic area, or has diabetes, high fever and rapid-developing disease, with additional presence of multiple inflammatory lesions in lung CT.
