The Case of Isabella Nutcracker

Pneumatized Tuberosity

Fig. 13.14 The images of this study are aligned parasagittallyat a slight angle in order to optimally demonstrate the function of the temporomandibular joint. The ventral side is on the left of the image. Images a and b depict the right joint, c and d the left joint. First localize the mandibular condyle, then identify its slip track along the articular tubercle, and finally find the low-signal disk. The upper part of the images shows the temporal lobe, the lower posterior part the pneumatized and therefore almost signal-free mastoid.
