Hi,
I am translating a complex brain MRI report from France.
In the Findings section under the title "En fosse postérieure" I have this sentence. What exactly do they mean by "peignés de la protubérance"?
Thanks
Joanna

C’est le cas de la dilatation des EPVR au
niveau des pédoncules cérébraux, de la substance
blanche sus-tentorielle, notamment en sous-cortical,
ainsi qu’au niveau des hippocampes. La dilatation
des EPVR au niveau de la substance blanche est
souvent responsable d’un aspect « peigné » de la

The comb sign indicates hypervascularity, it is most often applied to the mesentery in Crohn's disease.

https://radiopaedia.org/articles/comb-sign-mesentery
The comb sign refers to the hypervascular appearance of the mesentery in active Crohn disease. Fibrofatty proliferation and perivascular inflammatory infiltration outline the distended intestinal arcades. This forms linear densities on the mesenteric side of the affected segments of small bowel, which give the appearance of the teeth of a comb.
The sign may be seen on both CT and MRI. It is not pathognomonic of Crohn disease; however, in a known case of Crohn disease would suggest that the disease was extensive, advanced and active. However, the comb sign can be seen in other acute inflammatory conditions of bowel and lupus mesenteric vasculitis.
The comb sign may be used to differentiate active inflammatory conditions from lymphoma and metastases, which tend to be hypovascular.

Note from asker:
| Thanks Sue. Finally went with Liz's suggestion as I am not sure the patient has Crohn's disease. |

liz askew
: I did look at this but only found this in relation to Crohn's disease, not the brain, you give only one reference in relation to the brain
