What Is Your Neurologic Diagnosis?

摘要

A 6-year-old 3.9-kg (8.6-lb) spayed female indoor-only domestic medium hair cat was evaluated because of stupor, blindness, and a recent onset of seizure-like activity. During the preceding 3 days, the cat had become unsteady when standing, developedincreased respiratory rate and effort, and had an episode of vocalization and full-body rigidity. Two months prior to evaluation, the cat had been treated for and recovered from pneumonia; 1 week prior to evaluation, an abdominal mass (tentatively identified as an intra-abdominal lipoma) had been removed surgically. The cat had no history of travel outside of the Pacific Northwest, no longstanding medicalconditions, and no known toxin exposure. Other cats in the household were healthy.
