A 78-year-old man presented with a rare massive subarachnoid hematoma (SAH) in the cervical spine after coronary stenting for angina pectoris. Chest pain and electrocardiographic changes were resolved after administration of coronary dilator and coronary stenting, but shoulder pain persisted. At 6 hours after stenting, left hemiparesis was found with deteriorated shoulder pain. Computed tomography and magnetic resonance imaging revealed massive SAH in the cervical spine. Emergent hematoma evacuation with laminoplasty was performed because of rapid progression of the hemiparesis and pain. The hemiparesis was ameliorated after surgery. Spinal hematoma should be considered in the differential diagnosis in patients receiving anti-platelet or anti-coagulant drugs with rapid progression of pain.
