Pick's disease presenting with corticobasal syndrome: A case report and clinicopathological review.

Abstract

Pick's disease (PiD) is a rare form of frontal temporal lobar degeneration. The pathognomonic feature is atrophy of the frontotemporal lobes and intraneuronal deposits of 3R-τ inclusions, the Pick body. Corticobasal syndrome (CBS) is an atypical parkinsonian syndrome with a heterogeneous spectrum of underlying pathologies. We report a case of clinically diagnosed CBS with a post-mortem diagnosis of PiD and conduct a clinicopathological review of the literature on this unusual presentation.
