case_images: (a) The brain diffusion-weighted image MRI (DWI) of the patient is shown. Note the "heart appearance" lesion showing high intensity in the pontine base. (b) The brain apparent diffusion coefficient map MRI (ADC) of the patient is shown. The "heart appearance" lesion shows low intensity on ADC, indicating, in conjunction with the finding on DWI, that the lesion is a fresh infarct. (c) The brain magnetic resonance angiography (MRA) of the patient is shown. The basilar artery remains intact despite the bilateral involvement of the pons.

case_images: Brain MRI disclosed a "heart appearance" lesion in the pons (Figures 1(a) and 1(b)), which was high on diffusion-weighted image MRI (Figure 1(a)) and low on apparent diffusion coefficient map MRI (Figure 1(b)). Brain MRA demonstrated that the basilar artery remained intact (Figure 1(c)).
