Bilateral cerebellar infarction caused by rotational vertebral artery occlusion syndrome and intracranial vertebral artery dissection: a case report / 中华神经科杂志

ABSTRACT

Rotational vertebral artery occlusion syndrome, also known as bow hunter′s syndrome (BHS), is a rare cause of posterior circulation ischemia. Digital subtraction angiography (DSA) is still the gold standard for diagnosis. A case of bilateral cerebellar infarction, with color Doppler ultrasound showing special vertebral artery hemodynamic changes after head and neck rotation, was diagnosed by DSA as BHS and intracranial vertebral artery dissection. Based on the literature published previously, the clinical manifestations and imaging features of BHS were discussed to improve clinicians′ awareness of the syndrome.
