Pericardial effusion in a patient with lymphangioleiomyomatosis.

A 60-y-old woman with known lymphangioleiomyomatosis presented with a pericardial effusion. Chylous fluid was drained by pericardiocentesis, and EBV was demonstrated in the pericardial effusion. Treatment with a systemic antiviral agent removed the virus from the effusion. The effusion itself was treated surgically.
