MRA revealed the artery's condition. (A) Localized stenosis of P1 segment of bilateral posterior cerebral arteries. (B) Slender right vertebral artery. (C) Localized stenosis in the A2 segment of the bilateral anterior cerebral artery.

On admission, magnetic resonance imaging (MRI) of the cervical spine showed that the spinal cord measured normal in size, shape, and signal, the cervical disc herniation compressed the dural sac, the left vertebral artery's flow void signal was decreased, and the right vertebral artery was thin; magnetic resonance angiography (MRA) revealed the localized stenosis of P1 segment of bilateral posterior cerebral arteries (panel A), a poor local visualization of the C5 segment of bilateral internal carotid arteries, and the basal artery ring to be normal in size and shape, as shown in Figure 1; MRI of the head showed abnormal signals in midbrain and bilateral thalamus, considered cerebral infarction (top of the basilar syndrome), and soft tissue swelling was observed in the bilateral frontal, left parietal temporal, and left orbit areas. A2 segment of the bilateral anterior cerebral artery (panel C), as shown in Figure 1.
MRI revealed abnormal signals in the midbrain and thalamus. (A) The axial scanning of MRI revealed bilateral thalamic infarcts (DWI, diffusion-weighted imaging). (B) The axial scanning of MRI revealed Mesencephalic infarction (DWI, diffusion-weighted imaging). (C) The sagittal scanning of MRI revealed Mesencephalic infarction(T2-weighted MR images).

In Figure 2, abnormal signals are still visible in the thalamus and midbrain after the MRI scan taken on December 28, 2021.
