Pericardial Effusion Causing Cardiac Tamponade in a 10-Year-Old Male.

ABSTRACT

A 10-year-old male with a past medical history of premature pubarche, mild persistent asthma, and eczema presented to the emergency department with progressive dyspnea and chest pain. On examination, he was found to be tachycardic and tachypneic. Chest radiograph demonstrated cardiomegaly, bilateral pleural effusions, and scattered atelectasis. Echocardiogram revealed a large pericardial effusion with right atrial collapse. The patient was admitted to the pediatric ICU for pericardiocentesis and drain placement. As he later became hypertensive and febrile, we will discuss how our patient's hospital course guided our differential diagnosis and how we arrived at a definitive diagnosis using a multidisciplinary approach.
