Internal carotid artery dissection

Case contributed by A.Prof Frank Gaillard

Presentation

Right hemiplegia of over 24 hours duration.

Patient Data

Age: 60
Gender: Male
Modality: CT

Patchy left hemispheric and left basal ganglia hypodensities.

Modality: MRI

Occluded left internal carotid artery with perhaps a faint crescent sign seen on fat saturated T1 images through the neck, although note the mimicking appearance of flow in the adjacent jugular and contralateral ICA. 

Case Discussion

Features are consistent with ICA dissection and infarction presumably from artery to artery embolism, rather than occlusion (patchy infarction, not in a watershed distribution).
