Dilated Virchow Robin Space.

PROTOCOL:

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

FINDINGS:

-Evidence of a small linear area of altered signal is noted in the white matter of the right centrum semi ovale region measuring about 8.5 mm in diameter. It shows hypo intensity on T1; hyper intensity on T2 and Flair with no definite significant contrast enhancement.
-It also casts free diffusion on Diffusion and ADC maps images.

-The rest of the brain Parenchyma shows normal grey white matter differentiation and signal intensities.  No focal mass lesion is seen.
-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.
-Normal morphology of brain stem and cerebellum.
Fourth ventricle is normal in size and is midline in position.


OPINION:

• The non enhanced pattern of the previously mentioned lesion can exclude vascular lesion.
• Picture is suggestive of dilated Virchow Robin space for clinical correlation.
