The radiologic signs of dural ossification as depicted in the bone windows of CT were of 2 types:(1) the tram track sign, where there was a hyperdense bony excrescence with a hypodense center and (2) the comma sign, where there was evidence of ossification of one-half of the circumference of the duramater.
