ABSTRACT=Introduction: Multiple sclerosis (MS) and moyamoya (MM) are two separate diseases that rarely coexist. A special case with the two diseases coexisting was reported herein, and previously published articles were reviewed to investigate the clinical manifestations, management, outcomes, and underlying pathogenesis.
Patient concerns: A 42-year-old male presented with gradual right limb weakness and slow response for 3 months. However, these symptoms abruptly progressed during his hospital stay.
Diagnosis: This patient was diagnosed with coexisting MS and MM finally. The diagnosis of MS was made according to McDonald criteria of multiple lesions and multiple time episodes. Meanwhile, cerebral angiography indicated the diagnosis of MM.
Interventions: This patient was treated with methylprednisolone and antiplatelet drug and received bilateral superficial temporal artery bypass surgery for the occulted artery.
Outcomes: This patient's right limbs recovered to 4/5-grade muscle strength after 1 month of follow-up after hospital discharge, and his speech function improved after 3 months after hospital discharge.
Conclusion: We reported a rare scenario in a patient with the coexistence of MS and MM. We suspect that MS might induce immune response that plays a role in the pathogenesis of MM, while MM might accelerate the demyelination of MS. However, the pathogenesis and therapeutics of MM and MS coexistence need further investigation.
