Presentation of CaseA 69-year-old woman was admitted to the hospital because of a right orbital mass with chronic conjunctivitis.One month before admission she had noticed that her right eye was bloodshot. An ophthalmologist found a mass beneath the lateral aspect of the right lower lid with overlying conjunctival injection. Dexamethasone eye drops were prescribed. A computed tomographic (CT) scan of the orbits (Figure 1 and Figure 2) showed a slightly ill-defined, enhanced mass in the inferior and lateral anterior right orbit, without calcification or cavitation; there was no bone destruction, paranasal sinus disease, or evidence of an intraocular malignant tumor. . . .
