Figure 1 Neuroradiological and neurosonological evaluation. A and B: Axial fluid-attenuated inversion-recovery and diffusion-weighted imaging (DWI) brain magnetic resonance imaging sequences with subacute bilateral cerebellar ischaemic lesions involving the area supplied by the posterior inferior cerebellar artery; C and D: Axial and sagittal cervical computed tomography scan showing marked degenerative joint alterations with atlo-axial instability and retroposition of dens, spinal canal stenosis and ankilosis of lateral left zygo-apophisal joints with underlying congenital partial atlo-occipital fusion; E: Vertebral ultrasound examination documenting regular blood flow in the left VA in the neutral position (left side) and “stump flow” demodulation in both the V1-V2 and V3-V4 segments (right side) in cases of slight contralateral head rotation (20°).
