Ossification of the falx cerebri - focal

Case contributed by Dr Bruno Di Muzio


Incidental finding on a MRI Brain performed for dementia assessment.

Patient Data

Age: 69-year-old
Gender: Male

MRI Brain (selected images)

Selected images from MRI Brain demonstrate a right parafalcine well defined lesion that shows high T1 signal and is consistent with a focal area of ossification on the falx cerebri. 


CT Brain (selected images)

Selected images demonstrating a right parafalcine ossification of the falx cerebri. 

Case Discussion

Falx calcification and falx ossification are interchangeable terms in the radiology literature. They represent a benign condition and have, as in this case, a typical appearance on MRI consisting of a central marrow-containing portion with signal intensity similar to fat (bright on T1), surrounded by low signal intensity representing cortical bone. On CT there is no difficulty in identifying those findings.
