Abstract
To provide a description and thorough discussion of the diagnostic considerations for a rare case of malignant hypertension and aortic aneurysm in a pediatric patient. Case report. A university pediatric intensive care unit. A young child with a hypertensive crisis and a thoracoabdominal false aortic aneurysm. The child required urgent surgical intervention to resect the aneurysm and aggressive medical therapy in the pediatric intensive care unit to treat the underlying hypertension. Hypertensive emergencies and aortic aneurysms are unusual but potentially lethal entities in pediatric patients, requiring a high index of suspicion, prompt initiation of medical therapy, and urgent surgical consultation.
