@ecalabr So what’s the answer?!

Did you know sinonasal tumors could spread up the Eustachian tube into the ear? 👂

We present a multicenter series and systematic review of the fascinating and rare entity of sinonasal (Schneiderian) tumors in the temporal bone @TheAJNR

Freeze and C.M.

Chondrosarcoma typically exhibit adc values above 2, whereas chordomas tend to be around 0.8-1.5
