Spontaneous Spinal Epidural Haematoma Secondary to Autoimmune Acquired Haemophilia.

Spontaneous spinal epidural haematoma is a rare entity associated with high morbidity. Although there are previous reports of spinal haematoma secondary to X-linked genetic haemophilia, there are no such cases secondary to acquired autoimmune haemophilia. We report the case of a 71-year-old patient who presented with sudden quadriplegia secondary to cervical (C2 to T1) epidural haematoma as a result of undiagnosed autoimmune acquired haemophilia A. She underwent emergency cervical laminectomy and evacuation of spinal haematoma with significant recovery in upper limb function. This case highlights the importance of haematological investigations in patients with spontaneous spinal haematoma.
