Brain magnetic resonance images demonstrated the left TEME transethmoidal meningoencephalocele protruding into the ethmoidal sinus.
Computed tomography of the sinuses showed (1) an abnormal soft-tissue process causing expansion of the right maxillary sinus with complete opacification of the right maxillary antrum, (2) widening of the right ostiomeatal complex with mucosal thickening in the right-sided ethmoidal sinus cells, and (3) no violation of the bony wails separating the sinuses from the orbit or intracranial cavity (figure 1, A and B).
Considering each sinus separately, the lowest sensitivities were for the left maxillary sinus and right ethmoidal sinus (48 and 50%, respectively); the lowest specificities were for the ethmoidal sinuses (78 and 84%, respectively), whereas the specificity of all other sinuses was above 90%.
