A heavily calcified mass lesion is noted in the left cerebellar hemisphere, causing mild mass-effect upon the fourth ventricle, without surrounding edema or hydrocephaly.
From the case:
Calcifying pseudoneoplasm of neuraxis (CAPNON)
{"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/131683/annotated_viewer_json?iframe=true\u0026lang=us"}
There is a well-defined intra-axial left cerebellar hemisphere lesion, which appears hypointense on both T2 and FLAIR weighted images with blooming artefact and minimal surrounding edema. The mass causes mild mass-effect upon the fourth ventricle without evidence of hydrocephalus.
After intravenous contrast administration, there is evidence of heterogenous enhancement.
Case Discussion
These finding are suggesting a rare entity called calcifying pseudoneoplasm of neuraxis (CAPNON).
