Dorsal meningioma and subdural hematoma in a patient without risk factors for anticoagulation. Description of a very atypical case and review of the literature

Abstract Spontaneous hematomas associated with spinal meningiomas have been very rarely reported. They have been frequently associated with coagulation disorders or traumatic lumbar punctures. We report a case of a 72-year-old woman without coagulation disorders with a dorsal meningioma at D9-D10 level admitted in our hospital for scheduled surgical treatment. While awaiting surgery she developed an acute neurological worsening due to a subdural hematoma and required urgent surgical evacuation. After the surgery, the patient had a complete neurological recovery. This is probably the first case reported in the literature of this presentation to date.
