Short summary
Thoracic actinomycosis, a chronic bacterial infection, can be radiologically classified into parenchymal, airway, endobronchial, and mediastinal/chest wall types based on CT imaging.

Key points
- Thoracic actinomycosis is an uncommon, chronic suppurative bacterial infection caused by Actinomyces species.
- Risk factors include underlying respiratory disorders (emphysema, chronic bronchitis), poor oral hygiene, alcoholism, and chronic debilitating diseases.
- CT imaging can differentiate thoracic actinomycosis into parenchymal, bronchiectatic, endobronchial, and extrapulmonary patterns.
- Typical CT findings for the parenchymal pattern include central low density within consolidation and adjacent pleural thickening.

Abstract
BACKGROUND: Thoracic actinomycosis is an uncommon, chronic suppurative bacterial infection caused by actinomyces species, especially Actinomyces israelii. METHODS: It is usually seen in immunocompetent patients with respiratory disorders, poor oral hygiene, alcoholism and chronic debilitating diseases. RESULTS: We illustrate the radiological manifestations of thoracic actinomycoses in various involved areas in the thorax. CONCLUSION: Thoracic actinomycosis can be radiologically divided into the parenchymal type, the airway type including bronchiectasis, the endobronchial form, and the mediastinum or chest wall involvement type. TEACHING POINTS: • Important risk factors for thoracic actinomycosis are underlying respiratory disorders such as emphysema and chronic bronchitis. • Different CT patterns can be distinguished in thoracic actinomycosis: parenchymal, bronchiectatic, endobronchial and extrapulmonary. • Typical CT findings in the parenchymal pattern are a central low density within the parenchymal consolidation and adjacent pleural thickening.
