Hypersplenism Associated With Late-Presenting Congenital Diaphragmatic Hernia

Congenital diaphragmatic hernia (CDH) is a rare developmental anomaly of the diaphragm that mainly presents mainly in newborns. Even less common is late-onset CDH associated with hypersplenism. We report a 10-year-old male who presented with coughing, blood-stained sputum, and fever. He was diagnosed with CDH complicating hypersplenism after computed tomography was done. The patient was treated by CDH repair and splenectomy, and remained asymptomatic at 6-month follow-up. Computed tomography can be an important diagnostic option in this rare combination of CDH and hypersplenism, and surgical intervention is strongly recommended.
