A spinal subdural or epidural hematoma is an accumulation of blood in the subdural or epidural space that can mechanically compress the spinal cord. Diagnosis is by MRI or, if not immediately available, by CT myelography. Treatment is with immediate surgical drainage.

Spinal subdural or epidural hematoma (usually thoracic or lumbar) is rare but may result from back trauma, anticoagulant or thrombolytic therapy, or, in patients with bleeding diatheses, lumbar puncture.

Symptoms and Signs of Spinal Subdural or Epidural Hematoma

Diagnosis of Spinal Subdural or Epidural Hematoma

  • MRI

Hematoma is suspected in patients with symptoms and signs of acute, nontraumatic spinal cord compression or sudden, unexplained lower extremity paresis, particularly if a possible cause (eg, trauma, bleeding diathesis) is present.

Diagnosis of a spinal subdural or epidural hematoma is by MRI or, if MRI is not immediately available, by CT myelography.

Treatment of Spinal Subdural or Epidural Hematoma

  • Drainage

Treatment of a spinal subdural or epidural hematoma is immediate surgical drainage.

Patients taking warfarin or other vitamin K antagonist anticoagulants are given phytonadione (vitamin K1) 2.5 to 10 mg and fresh frozen plasma as needed to normalize the INR (international normalized ratio). phytonadione is given IV if urgent treatment is needed; it is given orally if treatment is not urgently needed. Patients with thrombocytopenia are given platelets Platelets Whole blood can provide improved oxygen-carrying capacity, volume expansion, and replacement of clotting factors and was previously recommended for rapid massive blood loss. However, because... read more .

Key Points

  • Suspect spinal subdural or epidural hematoma in patients with local or radicular back pain and percussion tenderness or sudden, unexplained lower-extremity paresis, particularly if a possible cause (eg, trauma, bleeding diathesis) is present.

  • Diagnose using MRI or, if MRI is not immediately available, CT myelography.

  • Immediately drain the hematoma surgically.
