BACKGROUND: Pulmonary involvement in Kaposi sarcoma is rare in children and can be difficult to distinguish from other pathology. OBJECTIVE: To describe the radiological findings in paediatric pulmonary Kaposi sarcoma. MATERIALS AND METHODS: Sequential chest radiographs of six children and CT scans of four of these children were evaluated retrospectively. Their ages ranged from 18 months to 10 years; four were male and two were female. All six children were HIV-positive. The observers were two radiologists. RESULTS: Chest radiographs revealed air-space (100%) and reticular (83%) opacification in the mid- and lower lung zones; pleural effusions were present in 83% of the children. All the children showed progressive air-space opacification on follow-up radiography. CT demonstrated bilateral air-space opacification in a perihilar distribution in all the children; reticular opacification was seen in 75%. All the children had mediastinal and axillary lymphadenopathy; 75% had bilateral hilar lymphadenopathy. CONCLUSION: In both adults and children, chest radiography demonstrates perihilar and lower zone involvement. Pleural effusions are more common on radiographs in children. Air-space disease and lymphadenopathy are much more common on CT in children than adults.
