a Axial noncontrast CT orbit of our patient. The implanted intraocular lens in the right eye measured 26 HU (SD 7.7 HU), Triesence in the dependent portion of the ocular globe measured 351 HU (SD 115 HU), and the SO occupying the vitreous chamber measured 78.9 HU (SD 5.7 HU). b Vials with Triesence 40 mg/mL, Kenalog 200 mg/5 mL, Triesence 0.5 mL concentrate, and Kenalog 2.5 mL concentrate were evaluated by CT scanning for Hounsfield density values, which were 330 HU, 309 HU, 242 HU, and 364 HU, respectively.

The CT scan showed a hyperintense lesion in the posterior segment of the left eye with bilateral pre-septal soft tissue swelling (Fig. 1a). Because of its oval and hyperattenuating appearance, the lesion in the CT scan initially seemed to resemble an IOL implant that dislocated posteriorly into the vitreous cavity (Fig. 1a). The radiographic attenuation of the lesion was determined to be 351 HU, while our patient's contralateral eye IOL implant was 26 HU (Fig. 1a). Triesence ranged between 242 and 330 HU (Fig. 1b), which was within the margin of error of the lesion's density (351 HU). The following day, the patient presented to the emergency room with new onset right eyelid edema (Fig. 2).
