Acute inferior homonymous quandrantanopia in a 71-year-old woman.

摘要

A 71-year-old woman presented with acute inferior homonymous quadrantanopia initially mimicking acute ischemic stroke. As clinical signs and symptoms progressed to akinetic mutism with myoclonus the diagnosis of the Heidenhain variant of Creutzfeldt-Jakob disease was made. Brain MRI 4 days after symptom onset revealed ribbon-like high signal intensity in the medial occipital cortex.
