Symptomatic Pericardial Effusion Associated With Graves' Disease in a Pediatric Patient

Abstract

Pericarditis is a well-known complication of hypothyroidism. Although pericarditis and pericardial effusions have been reported as rare complications of hyperthyroidism in adults, they are rarely reported in the pediatric population. In this case report, we describe a 12-year-old, previously healthy girl with nighttime chest pain, dyspnea, tachycardia, and abnormal thyroid function studies consistent with hyperthyroidism who was found to have pericarditis and pericardial effusion requiring pericardiocentesis.
