ABSTRACT
A 71-year-old, right-handed woman was admitted to our hospital due to a sudden difficulty with conversation. On admission, she was alert, but had a euphoric mood, disorientation, and a disturbance of recent memory. Her speech was fluent. Her repetition and auditory word cognition were excellent, but she had a slight difficulty with naming visual objects. She frequently showed word-finding difficulty and irrelevant paraphasia during free conversation and a word fluency task. Her irrelevant paraphasia was observed more frequently when she was asked to explain her outbreak of anger at the hospital, i.e., it was situation-dependent. She also had anosognosia. MRI showed an infarct in the territory of the left tuberothalamic artery. Single-photon emission computed tomography revealed low-uptake lesions in the left thalamus and orbital frontal, medial frontal, and medial temporal lobes. The patient was diagnosed with non-aphasic misnaming. The clinical characteristics of patients with non-aphasic misnaming in the literature were reviewed. All of the patients with non-aphasic misnaming had word-finding difficulty and irrelevant paraphasia. Additionally, they had either emotional disturbance or anosognosia.
