Presentation
Left facial droop and ataxia
Patient Data
Age: 85 years
Gender: Male
From the case:
Pontine infarct
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/41105/annotated_viewer_json?lang=us"}
Subtle wedge-shaped region of reduced attenuation in the left pons suspicious of acute ischemia which would correspond to the location of the facial nerve motor nucleus. No dense vessel sign (the basilar artery was normal on sagittal series and there was no thrombosis on CTA).
Mild deep and periventricular white mater hypodensity most likely represents chronic small vessel ischemia. No hemorrhage.

Wedge-shaped region of diffusion restriction in the left pons in keeping with acute infarct.
Case Discussion
Great example of a tiny infarct with major consequences when located at the exact location of a cranial nerve nucleus.
