CTICasesPulmonary Kaposi Sarcoma
Imaging findings
CT chest in a 53-year-old male with poorly controlled HIV shows subtle, shaggy, flame-shaped nodular opacities distributed along the peribronchovascular bundles in both lungs, in a patient with known cutaneous and gastrointestinal Kaposi's sarcoma.
Key takeaways
Kaposi sarcoma (KS) is a multicentric neoplasm caused by HHV-8, highly prevalent in poorly controlled HIV/AIDS. Pulmonary involvement classically presents as shaggy, flame-shaped or stellate nodules that track along the peribronchovascular interstitium. Airway lesions are commonly seen on bronchoscopy.
