Neuroimaging in a case of RCVS. Neuroimaging of a 61-year-old female with RCVS. (a) CT angiography demonstrated no evidence of vasospasm. (b) DSA demonstrated diffuse areas of focal segmental narrowing affecting both the anterior and posterior circulation, particularly in the A2 segment of the left anterior cerebral artery (arrow). (c) MRA showed predominantly peripheral focal segmental spasm, though not as clearly as the DSA (d) MRI 6 weeks after presentation reveals high T2 signal representing right occipital cortical infarcts. CT: computerised tomography; DSA: digital subtraction angiogram; MRA: magnetic resonance angiogram; MRI: magnetic resonance imaging.
