Choroid fissure cyst (MR).

PROTOCOL:

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

FINDINGS:

-A small cystic structure is noted arising from or related to a fissure in between the right thalamus and right Uncas measuring about 8.5 x 4.5 mm in diameters. It follows the intensity of CSF on all MR sequences; picture is suggestive of choroid fissure cyst.
-Notes of bilateral maxillary and ethmoidal sinusitis.

-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 mid line.  There is no mid line shift.
-Basal cisterns, cortical sulci and gyri are normal in appearance.
-Sella is normal in appearance. 
-Corpus callosum shows normal MR morphology.
-Brain stem and cerebellum show normal signal intensities.  
Fourth ventricle is normal in size and is mid line in position.


OPINION:

• On the light of the above mentioned MR findings; picture is suggestive of choroid fissure cyst.

• Notes of bilateral maxillary and ethmoidal sinusitis.
