Progress in Chest Computed Tomography Imaging of Chlamydia Psittaci Pneumonia

Chlamydia psittaci pneumonia, a lung infection caused by Chlamydia psittaci, is common among individuals with a history of close contact with birds. The infection can present with a variety of pulmonary symptoms. On diagnostic imaging, the infection mainly manifests as diffuse ground-glass opacities and pulmonary consolidation in the middle and lower lobes of both lungs, with or without bilateral pleural effusions. Chest computed tomography can help diagnose C. psittaci pneumonia, detect extrapulmonary signs in a timely manner, and provide close clinical monitoring of patients with severe clinical conditions. This article reviews the imaging findings of C. psittaci pneumonia to help radiologists better understand the characteristics of this infection.
