Factor X deficiency is a severe inherited coagulation disorder, which is characterized by severe systemic bleeding manifestations in affected individuals. It is a rare disorder with a frequency of around 1:1,000,000 in the general population. We present the case of an infant with factor X deficiency who presented with complex febrile seizure. Although febrile seizures are very common in children, a closer scrutiny leads to neuroimaging and finding of intracranial bleed. Hematologic and genetic investigations confirmed the diagnosis. A high index of suspicion should be maintained to diagnose uncommon bleeding disorders in children.
