More than meets the eye.

A 27-year-old woman was hospitalized with fever and visual changes. She had been well until nine months earlier when she developed unilateral blurry vision in the left eye. Ophthalmologic examination revealed bilateral acute anterior uveitis. She was treated with topical steroids and her vision returned to baseline. However, over the next few months, she developed debilitating fatigue and experienced an unintentional fifteen pound weight loss. One month prior to presentation, she noted the onset of daily low grade fevers and chills. On the day of admission, she developed a temperature of 103°F and a severe frontal headache. Here we describe a case where the overlap of clinical features led to an initially broad differential diagnosis of seemingly unrelated diseases. Ultimately, the discovery of a key radiographic finding allowed us to more clearly define the diagnosis.
