CT Pre and Post Contrast Skull: A rim contrast enhancing, centrally fluid attenuating and non contrast enhancing mass was seen extending from the level of the left ocular orbit caudally and ventrally towards the origin of the optic chiasm. This is causing dorsal and rostral exophthalmia. There was no evidence of bony involvement noted with this mass. There was no evidence of lymphadenopathy or other lesion. This lesion appears to be multi-lobulated or multi-loculated with fairly intense rim contrast enhancing and circling all components of this multi-compartmented mass lesion. There is periodontal lucency adjacent to the roots of the left first upper molar tooth. There appears to be discontinuity of the bone between the aforementioned cystic lesion and the periodontal region of that tooth.
Consider CT or fluoroscopy guided aspiration of the cystic contents for cytological
evaluation, drainage and better identification as to organ of origin. Consider oral examination for any evidence of abscessed tooth root. There is no evidence of an abscess on these images, although there is indication of discontinuity of the periodontal space with the retro-orbital space at the level of the first upper molar. Consider drainage for presumed abscess and biopsy of rim material for any possible neoplastic origin.
