Patient Data

Age: 60
Gender: Female

Cystic lesion in the prepontine cistern without enhancement or restricted diffusion extending into bone. 


Bony margins of the defect are smooth, and clearly non-aggressive. 

Case Discussion

Absence of enhancement or restricted diffusion together with non-aggressive bony margins in this location is typical of an retroclival ecchordosis physaliphora, a notochord remnant.
