PURPOSE: Classic late-infantile neuronal ceroid lipofuscinosis is characterized by progressive intellectual and motor deterioration, seizures, vision loss, and early death. Prominent chorea is an atypical feature and is rarely described in children.
METHODS: A four-year-old girl with seizures followed by a year-long progressive cognitive decline and a three month history of intermittent chorea leading to rapid motor deterioration. The onset of illness was marked by seizures occurring as generalized tonic-clonic seizures and myoclonic jerks. There was gradual regression of cognitive milestones with increasing forgetfulness and impaired quality and content of speech. Nine months later, she developed chorea. These movements were associated with clumsiness, incoordination, and progressive loss of motor milestones. She was unable to perform manual tasks or maintain antigravity posture resulting in unsteadiness and frequent falls. The movements were aggravated by action or excitement and were absent in sleep.
RESULTS: Magnetic resonance imaging depicted diffuse cerebral and cerebellar atrophy. Sequencing analysis of TPP1 gene showed a novel, homozygous, splice site mutation c.89+1G>A which resulted in nil enzyme activity and a severe phenotype with onset of disease symptoms at an early age of three years.
CONCLUSIONS: The presence of chorea in late-infantile neuronal ceroid lipofuscinoses is atypical but does not exclude the diagnosis of late-infantile neuronal ceroid lipofuscinoses, especially in children with psychomotor regression, seizures and diffuse brain atrophy.
