Man‐in‐the‐barrel syndrome‐like symptoms due to cervical infarction caused by transient hypoperfusion in the ascending cervical artery

Man‐in‐the‐barrel syndrome (MIBS) is characterized by weakness in the bilateral upper‐extremity muscles with relatively preserved strength in the face and lower‐extremity muscles. We present a case of MIBS‐like symptoms due to spinal cord infarction caused by transient hypoperfusion in the left ascending cervical artery (ACA) secondary to Stanford type A acute aortic dissection. To identify the ACA as the responsible artery, ischemic change by MRI of the longus colli muscle, which is primarily supplied by the ACA, was effective.
