Bilateral irregular pulmonary nodules that are predominantly located in the mid and lower zones with a peripheral and peribronchovascular distribution. Many of these lesions encase distal pulmonary artery branches, which appear dilated in some of the lesions. Some adjacent ground glass opacity. Bilateral hilar lymphadenopathy. No pleural or pericardial effusion.
Given the history of HIV, the CT appearances were considered suspicious for Kaposi sarcoma, and this suspicion was confirmed on percutaneous biopsy.
