Supplementary Material for: Early Screening and Identification of an Asymptomatic Pheochromocytoma in a child with Von-Hippel Lindau: a case report

Von Hippel-lindau (VHL) is a diagnosis that leads to increased risk of tumor development over the course of the patient’s lifetime. Patients with VHL undergo screening for multiple tumor types, including pheochromocytomas (PCC). There is not consensus among the different international guidelines regarding the age to begin PCC screening in VHL patients, though most recommend screening beginning at age 5 years. Here we present a case of an asymptomatic PCC identified in a 4-year-old on screening labs that was treated with laparoscopic partial adrenalectomy, supporting consideration for earlier initiation of screening in pediatric VHL patients.
