|Title||Choroid fissure cyst vs. Dilated VR space|
|Text||I always have trouble with this - and I may not be alone.
Choroid fissure cysts should connect to the choroid fissure. On sagittal images, the choroid fissure is just above the folded gray matter of the hippocampus. Choroid cysts should be posterior to the most anterior tip of the temporal horn. They are also inferior to the basal ganglia.
Dilated VR spaces are variable in size, but may be as large 1 cm or more in diameter. Located most commonly around the lenticulostriate arteries, they are found most often in the lower one-third of the basal ganglia. See also this factoid:
The CSF space in this case:
appears to be in the inferior frontal lobe basal ganglia or insular region, and not in the temporal lobe proper.
