RESUMO
BACKGROUND: Acute spontaneous spinal subdural hematoma associated with subacute cranial subdural hematoma is a rare entity. There is no precise age of presentation, and there is a slight female predominance. Origin is primary or secondary to hematologic factors or vascular and iatrogenic procedures. The main symptom is motor deficit in 57% of the cases. Surgical treatment is warranted only with neurological deficits. CLINICAL CASE: We present the case of a 44-year-old male with severe headache and diagnosis of subacute frontoparietotemporal subdural hematoma and signs of lumbar radiculopathy. Prognosis is proportional to the initial neurologic deficit. CONCLUSIONS: Patients with cranial subdural hematoma who develop neurological symptoms in the lower extremities should have magnetic resonance imaging study to rule out spinal subdural hematoma.
