CT scan
CT Axial image shows sphenoid sinus
(SpS) and the sphenoethmoidal recess marked by the (*). (AE: anterior ethmoid,
PE: posterior ethmoid, CC: carotid canal, NS: nasal septum(.
CT coronal image shows ethmoid bulla
air cells superior to uncinate processes. The (*) highlight the hiatus
semilunaris. Ethmoid bulla air cells are part of the anterior ethmoid sinuses
and make up the superior border of the hiatus semilunaris. (EB:ethmoid bulla,
U: uncinate process, MT: middle turbinate).
CT scan coronal image demonstrating
frontal recess (arrows), hiatus semilunaris (*) and middle meatus (arrowheads).
(EB: ethmoid bulla, MT: middle turbinate, MS: maxillary sinus(
CT scan coronal image with arrows
demonstrating overly pneumatized frontal sinuses. Also note enlarged ethmoid
bulla air cells (arrowheads(.
CT scan coronal image showing pneumatized
lateral recesses of sphenoid sinus (SpS) and foramen rotundum (FR) bulging into
the sinus. Arrows point to optic canals superior to sphenoid sinus and medial
to anterior clinoid processes.
