(15) Similar to the literature, in this study, the most common origin of the mucoceles were frontal sinus (54.5%) and ethmoidal sinus (27.3%), which due to the mass effect in the orbital cavity, resulted mostly in proptosis (63.6%), diplopia (54.5%), and displacement of the globe (36.4%).
Brain magnetic resonance images demonstrated the left TEME transethmoidal meningoencephalocele protruding into the ethmoidal sinus. In conclusion, TEME should be considered in patients with recurrent bacterial meningitis.
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).
A CT scan revealed that the foreign body had penetrated the left ethmoidal sinus through the medial wall of the orbit and reached the anterior skull base, with about 8 mm penetrating into the intracranial region [Figure 1]a,[Figure 1]b,[Figure 1]c.
