Аннотация
BACKGROUND CONTEXT: Many cases of nontraumatic spinal epidural hematoma (SEH) have been reported, although the etiology of SEH remains unclear.
PURPOSE: Our purpose was to report a rare case of nontraumatic acute SEH caused by extradural varices and to discuss the etiology of this entity.
STUDY DESIGN/SETTING: Case report.
PATIENT SAMPLE: A 27-year-old man.
OUTCOME MEASURES: Resolution of the patient's paraplegia, and pathological examination of the epidural vein of the patient and three other patients with cervical spondylosis.
METHODS: Not applicable.
RESULTS: The patient recovered from paresis of both hands, although paraplegia remains complete. Pathological examination of the patient revealed abnormal veins that had thickened walls, varying caliber, and internal elastic lamina. In two of the three patients with cervical spondylosis, abnormally dilated veins resembling those in the SEH patient were observed.
CONCLUSIONS: We describe a rare case of SEH caused by extradural varices. It is speculated that spinal epidural veins can possibly develop an abnormal structure and fragility as seen in the present case and in spondylotic cases.
