title: Intraorbital glass foreign body missed on CT imaging.
abstract: A 36-year-old woman presented with a 7-week history of foreign body sensation in the superior right orbit after orbital trauma sustained during an accidental face-down fall onto a broken drinking glass. CT identified a 10.35 x 3.91-mm radiopaque foreign body in the right orbit superolateral to the globe. Orbital exploration superficial to the levator palpebrae superioris aponeurosis in close proximity to the site occupied by the CT-identified foreign body revealed an additional glass intraorbital foreign body, 4.0 x 2.5 x 0.25 mm in dimension. The second glass foreign body was entirely missed on the preoperative, 1-mm axial scans combined with sagittal and coronal reconstructed images and plain radiography.
