Body
was changed:
Meningothelial Hyperplasia (MH) is a poorly characterized entity and occasionally causes diagnostic difficulties due to its overlapping histologic features with meningioma.
MH is a reactive process characterized by a proliferation of meningothelial cells that reaches a thickness of 10ten or more cell layers with PR positivity, which is not seen in normal cells.
Brain MRI shows an remarkable accentuation of the parenchymal vessels throughout the full-thickness thickness of the cortex and whittewhite matter.
This case was presented in Eurorad, but.
Due to the authors want to share with radiopaediaMRI findings, a stereotactic biopsy was performed by the treating neurosurgical team.

Findings
was changed:
MR Brain MRI demonstratedemonstrates diffuse engorgement and accentuation of parenchymlthe parenchymal vessels.
Images Changes:
Image MRI (T1 C+) ( update )
Description
was changed:
Gadolinium-enhanced imagesdemonstrate diffuse engorgement of multiple vascular structures extending from hemispheric cortex through subcortical white matter, deep white matter and subependymal margins on both cerebral hemispheres as well as throughout cerebellum and brainstem.
Image MRI (SWI) ( update )
Description
was changed:
Susceptibility weighted images demonstrates a demonstrate remarkable accentuation of the parenchymal vessels.
Image MRI (MRA) ( update )
Description
was changed:
There is no recognizable venous obstruction to account for vascular engorgement. There is not a dural fistula.
