Pontine infarct

Case contributed by Dr Craig Hacking

Presentation

Left facial droop and ataxia

Patient Data

Age: 83
Gender: Male
Modality: CT

Subtle wedge-shaped region of reduced attenuation in the left pons suspicious of acute ischaemia 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 ischaemia. No haemorrhage.

Modality: MRI

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.
