title: Atypical neuronal ceroid-lipofuscinosis.
abstract: We describe the clinical, pathologic, and ultrastructural findings in a case of juvenile onset neuronal ceroid-lipofuscinosis without visual symptoms or retinal abnormalities. The histochemical and ultrastructural characteristics of the neuronal lipopigment were similar to those in typical cases of neuronal ceroid-lipofuscinosis. Atypical neuronal ceroid-lipofuscinosis may be distinguished histochemically, ultrastructurally, and clinically from another disorder called juvenile dystonic lipidosis, with which it has been confused.
