Intra ventricular ependymal cyst (MR).

PROTOCOL:

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

FINDINGS:

-A small intra ventricular cyst is seen in the temporal horn of the right ventricle measuring about 7.2 x 7.2 x 5.8 mm in diameters. It follows the intensity of the CSF on all sequences.
-It causes compression and thinning of the right Hippocampus.
-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.
-Brain stem and cerebellum show normal signal intensities.
-Fourth ventricle is normal in size and is midline in position.


OPINION:
• Picture is suggestive of intra ventricular cyst in the temporal horn of the right lateral ventricle causing compression of the right Hippocampus most likely an ependymal cyst for clinical correlation.
