Multiple Pulmonary Nodules in an Immunocompetent Adolescent with Infectious Mononucleosis.

BACKGROUND: Infectious mononucleosis is usually a self-limiting illness, but can be rarely associated with complications. CASE CHARACTERISTICS: A 17-year-old boy with Epstein-Barr virus related infectious mononucleosis and cold antibody-mediated autoimmune hemolytic anemia with incidentally noted multiple pulmonary nodules. OBSERVATIONS: Nodules regressed over the next few weeks without specific therapy. MESSAGE: Pediatricians need to be aware of this rare clinical presentation of infectious mononucleosis so that further invasive testing can be avoided.
