Enhancement within the orbits and superficial temporal artery: MRI clues to the diagnosis of giant cell arteritis.

Purpose: Giant cell arteritis can have protean manifestations, many of them non-specific. We describe a patient whose initial presentation was most consistent with brainstem stroke, but who was ultimately diagnosed with and treated for giant cell arteritis.

Observations: A 76-year-old woman presented with abrupt onset diplopia, headache, nausea and vomiting.

The Neuro-Ophthalmology Virtual Education Library (NOVEL).

The Neuro-Ophthalmology Virtual Education Library (NOVEL) is the largest online, open-access, repository of neuro-ophthalmology educational material. It contains nearly 20,000 learning objects, including textbooks, PDFs, PowerPoints, videos, and images in a variety of individual and group collections. The purpose of this letter is to increase awareness of this invaluable resource for neuro-ophthalmology education.

Diagnostic dilemma: Leber's hereditary optic neuropathy in a 70-year-Old woman.

Purpose: Reports of atypical cases have increased awareness that Leber's hereditary optic neuropathy (LHON) is not solely a disease of young men. Here, we present a case of a 70-year-old woman who presented with bilateral sequential loss of vision, and, after several diagnostic dilemmas, was ultimately found to have LHON.

Observations: Our patient presented with a one-month history of progressive central vision loss in the right eye.
