Posterior circulation insufficiency with multiple infractions (MR).

PROTOCOL:

T1W – Sagittal & axial scans
T2W – Axial & coronal scans
FLAIR – Axial scans 

FINDINGS:

-Revealed:
• Multiple variable sized foci of altered MR signals in both cerebellar hemispheres with the largest one diameter 22 x 12 mm on the right side.
• Another focus in the left thalamus and in the left occipital region.
• Small vessel ischemic disease with grade I Fazekas classification.
• Non visualization of the left vertebral artery (occluded) on MR angiography.

-Lateral and third ventricles are normal in size and position. Septum is in midline.  There is no midline shift.
-Basal cisterns, cortical sulci and gyri are normal in appearance.
-Sella is normal in appearance. 
-Corpus callosum shows normal MR morphology.
-Brain stem shows normal signal intensities.  
-Fourth ventricle is normal in size and is midline in position.


OPINION:

• On the light of the MR findings; picture is suggestive of posterior circulation insufficiency with multiple infarcts as described with completely occluded left vertebral artery.
