A CT scan of the sinuses without contrast revealed hyperdense soft tissue opacifying the right sphenoid sinus extending to the right posterior ethmoidal air cells with osseous erosive changes; erosion of the right anterior wall of the sphenoid sinus, posterior right ethmoidal air cell septi; and mild erosion of the posterior medial walls of the maxillary sinus and medial wall of the orbit with minimal soft tissue extending to the orbital apex.
We defined disruption or instability of syndesmosis as the following: intraoperative AP radiograph that demonstrates a clear space of more than 6 mm between the medial wall of the fibula and the lateral wall of the posterior tibial malleolus, or distal tibiofibular overlapping of <5 mm measured 1 cm proximal of the tibial plafond, or a difference of more than 2 mm side-to-side in the tibiotalar or tibiofibular clear spaces on mortise radiographs.[22] As previously mentioned, in these PER injuries with SMM fractures, positive prebony-fixation stress test and negative postbony-fixation stress test were observed.
Within the orbit, it was close to the medial wall of the globe, the walls of which were intact.
Paranasal sinus MRI revealed molding of the medial wall of left cavernous sinus by the sphenoid mass (Figure 1(a)).
Anteroposterior pelvic radiography revealed migration of the acetabular cup into the pelvis with destruction of the medial wall of the acetabulum (Figure 1(a)).
The disease was extensive with a destruction of the EAC circumferentially, exposing facial nerve, bowing of pars tensa touching the medial wall of the mesotympanum (Figure 3).
Ratings for this montage also depended more on occipital medial wall current densities than on current densities in the remainder of the occipital lobe.
Computed tomography revealed a mass lesion that completely filled the left maxillary sinus, obliterated the ostiomeatal unit, and caused destruction of the lateral wall of the sinus; it also showed a tooth in the medial wall of the sinus (Figure 1).
The medial wall of the lacrimal sac movement can be appreciated by applying gentle pressure over the eyeball.
In addition to diffuse wall thickening (1 cm) of a 10-cm segment of the sigmoid colon, the surrounding mesenteric tissue had an increased density and the medial wall of the adjacent sigmoid colon included a millimetric air density, consistent with a diagnosis of sigmoid diverticulitis with a closed perforation.
(c) The white arrow indicates the distance between the center of the promontorium and the medial wall of the right CIV (R-CIV), and the black arrow indicates the distance between the center of the promontorium and the medial wall of the left CIV (L-CIV).
