Conservative therapy for spinal epidural hematoma in a child with hemophilia A with high-titer VIII inhibitors

Abstract

The occurrence of a spinal epidural hematoma in patients with hemophilia A with high-titer VIII inhibitors is extremely rare and intractable. A 15-year-old male patient presented to our institution with acute back pain and progressive sensorimotor disorder of the bilateral lower extremities. He had hemophilia A with high-titer VIII inhibitors and had experienced recurrent hemorrhagic episodes for many years. Prompt magnetic resonance imaging revealed a spinal epidural hematoma. We administered bypassing agent therapy with prothrombin complex concentrates and performed intensive neurological monitoring. The neurological dysfunction improved with days, and the patient recovered completely within 3 weeks. Magnetic resonance imaging 1 year later showed that the hematoma had been completely absorbed. Spinal epidural hematomas in patients with hemophilia A with high-titer inhibitors can be successfully treated using prothrombin complex concentrates. Multidisciplinary discussions based on intensive neurological monitoring should be performed as early in the clinical course as possible.
