The above image is from a patient with a history of HIV and lymphoma. CECT demonstrates a thickened, enhancing pericardium with a complex pericardial effusion. Bilateral pleural effusions, right greater than left, are also noted.
Pericardial effusions are the most common cardiovascular complication of HIV infection and usually carry a poor prognosis. The majority of cases are due to an idiopathic cause. Other causes that must be considered in this population are tuberculosis, bacterial infection (S. aureus is the most common), malignancy (lymphoma and Kaposi's sarcoma), viral, and fungal.
