Neville and coauthors (1973) reported several cases of neurovisceral storage disease with vertical supranuclear gaze paresis, ataxia and other central nervous disorders. This disease is classified into Niemann-Pick disease type C because of the presence of foamy cells or sea-blue histiocytes in bone marrow, and the accumulation of sphingomyelin, cholesterol and other glycosphingolipids. In this paper, we reported a rare case of neurovisceral storage disease with severe horizontal supranuclear ophthalmoplegia and sea-blue histiocyte in bone marrow. The patient was a 9-year-old boy. He was hospitalized for unstable gait. The neurological examination revealed severe horizontal supranuclear ophthalmoplegia, moderate ataxia of four extremities and trunk, and mild dystonia of neck and four limbs on walking and standing. The ocular movement in the vertical direction was less impaired and his mentality was almost normal. The bone marrow aspiration showed a few sea-blue histiocytes. The activities of fibroblast lysosomal enzymes including sphingomyelinase were normal. The rectal biopsy revealed many foamy cells in mucous membrane and submucosa. The cell had PAS-positive and acid phosphatase-positive substances, which showed rose-red metachromasia with Feyrter's thionin method. But these abnormal cells were never stained by Sudan black B. These histochemical reactions were compatible with those of Neville's neurovisceral storage disease (Lake, 1983). Therefore we supposed the pathogenesis of this case was the same as that of Neville's cases. In this case, the horizontal supranuclear ophthalmoplegia was a unique symptom.

Analysis of the neurologic symptomatology in 22 patients with Niemann-Pick disease type C revealed 3 phenotypes: (1) an early-onset, rapidly progressive form associated with severe hepatic dysfunction and psychomotor delay during infancy and later with supranuclear vertical gaze paresis, ataxia, marked spasticity, and dementia; (2) a delayed-onset, slowly progressive form heralded by the appearance, usually in early childhood, of mild intellectual impairment, supranuclear vertical gaze paresis, and ataxia, and later associated with dementia and, variably, seizures and extrapyramidal deficits; (3) a late-onset slowly progressive form distinguished from the 2nd pattern by later age of onset (adolescence or adulthood) and a much slower rate of progression. The existence of the 1st and 2nd phenotypes within the same sibship suggests that they are variant expressions of the same clinicopathologic disorder. Niemann-Pick disease type C should be considered not only in infants and children who present with organomegaly and a progressive neurodegenerative course, but also in adolescents and adults who have insidiously progressive neurologic dysfunction and only slight organomegaly. Associated with the disease is a marked deficiency in the ability of cultured fibroblasts to esterify exogenously supplied cholesterol. Assay of this deficiency is particularly useful for confirming the diagnosis in patients with atypical presentation.

Nine patients with a progressive neurologic disorder that was characterized by mental deterioration, supranuclear vertical gaze paresis, and foam cells or sea-blue histiocytes in the bone marrow are described and compared with patients who were previously described as having " neurovisceral storage disease with vertical supranuclear ophthalmoplegia" and "dystonic lipidosis." The clinical manifestations of our patients and those described by others and the pathologic findings and profiles of lipid analysis reported by others are similar to those in patients with Niemann-Pick disease, type C. Sphingomyelinase activities in leukocytes and skin fibroblasts were normal in our patients and in more than half of the reported cases; these findings are also compatible with those in patients with Niemann-Pick disease, type C. Until the biochemical and genetic abnormalities of Niemann-Pick disease, type C are clearly defined, it is justifiable to classify the disorder under discussion as a subgroup of Niemann-Pick disease, type C because it seems to be a heterogeneous group. From the clinical point of view, the diagnosis is difficult to establish in the absence of abnormalities in the bone marrow in patients who are older than 20 years; repeat examinations of the bone marrow are necessary in such patients. Clinicians should be aware of this disorder not only in patients in the first and second decades of life, when this disorder usually becomes symptomatic, but also in patients in the fourth and fifth decades.

Abnormal copper metabolism has been linked with neurological disorders, such as Wilson and Menkes disease. Another disorder causing symptoms similar to copper metabolism disorder is Niemann-Pick type C. However, a definite pathophysiological connection between Niemann-Pick type C and copper metabolism disorders has never been established. The authors present an adolescent with an unusual presentation of copper deficiency-dysarthria, ataxia, and vertical gaze paresis, without significant cognitive degeneration or pathological magnetic resonance imaging (MRI). The patient was found to carry 2 mutations in the NPC1 gene. A possible link, explaining how copper deficiency might induce the Niemann-Pick phenotype might involve overproduction of cholesterol and inhibition of acid sphingomyelinase. We suggest that copper metabolism disorders be included in the differential diagnosis for ataxia and dysarthria, even in cases with unusual presentations. Moreover, should the connection between copper and Niemann-Pick be validated, screening for copper metabolism disorders may be advisable in Niemann-Pick type C patients and vice-versa.
