A 14-Year-Old Female With Chest Mass, Shortness of Breath, and Hypertension.

Abstract

A previously healthy 14-year-old girl was evaluated in the emergency department (ED) with 2 months of shortness of breath and fatigue. She initially presented to her primary pediatrician, where a complete blood count was only significant for mild anemia, thyroid function tests were normal, and a chest x-ray revealed a chest mass. This prompted her primary pediatrician to order a computed tomography scan and refer to the ED. Her computed tomography scan confirmed a mediastinal mass versus necrotic lymphadenopathy. Her initial physical exam was unremarkable, except for hypertension. From the ED, she was admitted to the pediatric hospital medicine service. Infectious disease, oncology, and nephrology services were consulted to guide diagnostic evaluation. Eventually, during her hospitalization, further history and workup led to a definitive diagnosis.
