Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headache with reversible vasoconstriction of the cerebral arteries. RCVS has been reported to occur in various clinical settings. However, RCVS triggered by blood transfusion is rare. A 50-year-old woman had severe anemia and received multiple blood transfusions. She developed thunderclap headache after transfusion. Cerebral artery vasoconstrictions were demonstrated by magnetic resonance angiography and transfemoral cerebral angiography. RCVS might be triggered by red blood cell transfusion in patients with severe anemia.

Man-in-the-barrel syndrome (MIBS) is a clinical syndrome of bilateral upper limb weakness with normal lower extremity function. It can be caused by various neurological conditions such as bilateral cerebral hypoperfusion, syringomyelia, motor neuron disease, or cervical myelopathies. We report a patient with MIBS after cervical spinal cord ischemia. It is postulated to be caused by ischemic insults of anterior spinal artery from repeated and prolonged neck extension.
