Pulmonary embolism in a 13-year-old boyFREEMAN, LISA MDPediatric Emergency Care: December 1999 Illustrative Case: PDF Only Abstract Pulmonary embolism and thromboembolic disease are uncommon entities in the pediatric population. The importance of risk factor assessment is paramount to considering the diagnosis in children. Clinical presentations are similar to those in adults; however, children may present with minimal objective findings on preliminary ancillary testing that would make one consider pulmonary embolus as a diagnosis. This report involves a 13-year-old boy with a well-defined risk factor for thromboembolism who presented with a classic history and without hypoxemia. © 1999 Lippincott Williams & Wilkins, Inc.
