case_images: CT scan of the head without contrast immediately after the procedure. A: Residual contrast from cardiac catheterization noted in bilateral occipital lobes. B: Similar residual contrast noted in bilateral cerebellar lobes.

case_images: A computed tomography (CT) scan of the head without contrast taken just after the event was limited due to the presence of contrast (Fig. 1).
case_images: Magnetic resonance imaging (MRI) on the day of presentation. A, B: Diffusion-weighted images with showing punctate hyperintense lesions in bilateral occipital lobes. C: Fluid-attenuated inversion recovery (FLAIR) showing abnormal hyperintensities in bilateral cerebellum, right greater than left. D: Diffusion-weighted images of the cerebellum not showing any hyperintense abnormalities. E: Apparent diffusion coefficient (ADC) image corresponding to image A showing hypointense punctate lesions. F: Gradient echo (GRE) image with no evidence of hemorrhage. G: T2-weighted image showing findings similar to the FLAIR image. H: ADC image of the cerebellum not showing any hypointense abnormalities.

case_images: The cerebellar infarct on the right was larger than that in the left hemisphere (Fig. 2).
case_images: Magnetic resonance imaging (MRI) performed 12 days after the initial presentation. A, D: Diffusion-weighted images with arrows not showing punctate hyperintense lesions in the occipital lobes noted in Fig. 2. B: FLAIR image of the cerebellum showing improved bilateral hyperintensities. C: ADC image of the cerebellum not showing any hypointense abnormalities. E: T2-weighted image showing similar findings to the FLAIR image. F: Diffusion-weighted images of the cerebellum not showing any hyperintense abnormalities.

case_images: MRI obtained 12 days after the initial presentation showed a less intense but persistently increased T2 signal in the cerebellar hemispheres without occipital infarcts (Fig. 3).
