CASE HISTORY

A 60-year-old female with chronic lymphocytic leukemia sought treatment after experiencing double vision for 3 weeks. She also noted difficulty with her balance and ambulation. She was evaluated by her oncologist who referred her for magnetic resonance (MR) imaging (Fig. [1]). On physical examination, she was alert and oriented. Her speech was clear. Her extraocular muscles were intact, her tongue was midline, her hearing was grossly normal, and the remainder of her cranial nerves were intact. She had pronounced dysmetria on the right side. In addition, the patient had a positive Romberg's sign as well as an ataxic gait.
