Presentation
Mass filling within the right orbit.
Patient Data
Well-defined cystic lesion, measuring 28 x 20 x 19 mm is noted at medial portion of right orbit with extension into nasolacrimal duct. The lesion is slightly high signal on T1w and bright signal on T2w images in favor of high proteineous contents.
The right globe is displaced laterally and proximal portion of nasolacrimal duct is dilated.
Case Discussion
Features of MRI are compatible with right dacryocystocele (acquired).
Dacryocystocele commonly manifest as a tense, blue-gray mass at the medial canthus or in the nasal cavity due to primary or acquired nasolacrimal duct obstruction.
