Abstract:
Objective:Through a typical case of corticobasal degeneration (CBD) with primary progressive aphasia (PPA) to analyze the clinical characteristics of CBD and the special manifestations of aphasia with that disease.Methods:Retrospective analysis was performed on a patient with PPA based CBD who was admitted to the First Affiliated Hospital, Sun Yat-sen University in July 2020 to summarize the clinical features and diagnostic thinking of CBD.Results:The patient was a 59-year-old male, manifested rapidly progressive dysfunction of language and memory function. The aphasia was mainly featured as slow speech, reduced content and grammatical errors, and diagnosed as PPA, non-fluent grammatical variation. The imaging results showed the atrophy of the left frontal lobe, parietal lobe, basal ganglia and thalamus, coupled with the reduction in 18F-fluorodeoxyglucose radioactive uptake. The patient was finally diagnosed as possible CBD. Conclusions:PPA as the initial manifestation of CBD is very rare in clinical practice. The high non-specificity of clinical features and the lack of typical motor symptoms result in the difficulty of correct diagnosis of CBD. Timely functional imaging in nuclear medicine and reliable biomarkers help to facilitate early diagnosis of atypical CBD.
