Pulmonary actinomycosis typically presents as a single lung mass. This case highlights multiple, bilateral nodules and a liver mass, suggesting spread from the liver to the lungs.

Area of Science:

Pulmonology
Infectious Diseases
Radiology

Background:

Pulmonary actinomycosis is an uncommon bacterial infection.
Computed tomography (CT) is a key imaging modality for diagnosis.
Typical CT findings often include solitary, unilateral lesions.

Observation:

This case presented a unique thoracic CT finding of pulmonary actinomycosis.
Multiple, bilateral, small pulmonary parenchymal nodules were observed.
An associated liver mass was identified concurrently.

Findings:

Histological confirmation of actinomycosis was obtained.
The imaging findings suggest hematogenous dissemination.
The likely route of spread was from the liver to the lungs via hepatic veins.

Implications:

This case expands the spectrum of imaging findings for pulmonary actinomycosis.
It emphasizes the importance of considering hepatic involvement in pulmonary actinomycosis.
Radiologists and clinicians should be aware of this atypical presentation for timely diagnosis and treatment.
