CTICasesDisseminated Strongyloides Infection
Imaging findings
Chest CT shows numerous diffuse, very small, predominantly centrilobular nodules with relative sparing of the subpleural space, mimicking a random or miliary pattern. The findings are superposed on aspiration pneumonia in an immunocompromised patient.
Key takeaways
Disseminated Strongyloides stercoralis infection can occur in severely immunocompromised individuals, where larvae migrate from the intestine, carry enteric bacteria, and lodge in the pulmonary arterioles. This can present as diffuse, miliary-like centrilobular nodules on chest CT.
