Lacrimal Gland Ischemia due to Giant Cell Arteritis
The present case has been published in the journal Ophthalmology. An 83-year-old man presented with rapid onset of right eye exophthalmos (Fig 1A). A diagnosis of lymphoma was considered after an emergency magnetic resonance imaging (MRI) showed an enlarged lacrimal gland with restricted diffusion (Fig 1B, white arrowhead).

A preoperative MRI performed 1 month later ruled out lymphoma, with a normalized diffusion (Fig 1C, white arrowhead) but revealed an arterial inflammation of both the temporal (Fig 1D, arrows) and lacrimal arteries (Fig 1E, black arrowhead). A temporal artery biopsy confirmed the diagnosis of giant cell arteritis (Fig 1F), which was treated successfully with steroids.

The final diagnosis was an ischemia of the right lacrimal gland due to a lacrimal artery inflammation. (Magnified version of Fig 1A-F is available online at
