: Niemann-Pick type C (NPC) disease is an autosomal recessive disease of lysosomal lipid storage disorder caused by mutations in either the NPC1 (95%) or the NPC2 (5%) gene. We report a case of a 23-year-old woman who initially showed ataxia, altered gait and tremor. She subsequently developed cognitive decline and psychiatric symptoms. She had asphyxia at birth and was diagnosed as hypoxic-ischemic encephalopathy and cerebral palsy before. The chest computed tomography (CT) incidentally showed splenomegaly. Brain magnetic resonance imaging (MRI) showed no significant abnormalities. Genetic analysis revealed compound heterozygous mutations of NPC1. The clinical picture of NPC can be markedly variable, so comprehensive clinical evaluation, neurological examination and laboratory test are quite important for the diagnosis of NPC.
