Imaging findings
CT chest in a patient with HIV/AIDS shows characteristic flame-shaped, nodular thickening along the bronchovascular bundles and interlobular septa, associated with bilateral pleural effusions.
Key takeaways
Pulmonary Kaposi sarcoma typically has a bronchocentric distribution, following the lymphatic pathways of the bronchovascular sheath. The 'flame-shaped' appearance is a classic CT sign that helps differentiate it from lymphoma or atypical infections, and requires correlation with skin findings.
