From the case:
Intraventricular simple cyst
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/125995/annotated_viewer_json?iframe=true\u0026lang=us"}
MRI demonstrates a thin-walled cystic lesion in the right ventricular trigone with signal intensity similar to CSF on all sequences. A minimal dilatation of the right occipital horn is noted. There is no periventricular edema.
Case Discussion
MRI features are suggestive of an intraventricular simple cyst.
The origin of these cysts is unclear, and the distinction between intraventricular arachnoid cysts, ependymal cysts, neuroepithelial cysts, or choroid plexus cysts is impossible according to MRI results.
