X‐Linked Chronic Granulomatous Disease: Initial Presentation with Intracranial Hemorrhage from Vitamin K Deficiency in Infant

Abstract

Vitamin K deficiency bleeding (VKDB) is a life‐threatening condition and can be found in children as early as neonatal period with early onset intracranial hemorrhage (ICH). Here, we reported a 1‐year‐old boy who initially presented with intracranial hemorrhage secondary to vitamin K deficiency since 3 months of age and later found to have XL‐CGD which was complicated by malabsorption due to severe vaccine‐associated mycobacterial disease.
