The axial brain fluid-attenuation inversion recovery (FLAIR) images (A) and sagittal T2-weighted images (B), demonstrating a "heart-shaped" appearance area of hyperintensity located in the tegmentum of the caudal midbrain.

A 3.0 MRI of the brain, performed 24 h after admission, showed a "heart or V"-shaped lesion in the tegmentum location of the caudal midbrain (Figure 1).
(A) The brain diffusion-weighted image (DWI) of the patient is shown. Note the "heart or V"-shaped lesion showing increased intensity in the tegmentum of the caudal midbrain. (B) The brain apparent diffusion coefficient map MRI (ADC) of the patient is shown. The "heart or V"-shaped lesion shows low intensity on ADC, consistent with acute infarction.

Additionally, there was increased signal intensity on diffusion-weighted image MRI (Figure 2A) and low apparent diffusion coefficient map MRI (Figure 2B), in line with acute infarction.
1.5T Brain MRI, axial T2-weighted images (A) and coronal T2-weighted images (B) shows the symmetric enlargement and increased signal intensity of both inferior olives (arrow).

A 1.5-T MRI scanner revealed a hyperintensity and hypertrophy of the bilaterally inferior olivary nucleus on T2WI (Figure 3).
