The pitfall of silent neurosarcoidosis.

Sarcoidosis in childhood is seldom reported. Most cases are observed in older children and preadolescents as bilateral pulmonary disease and eye lesions. Arthritic features are more likely to be observed in infants and children younger than 4 years of age who do not develop pulmonary disease. Neurosarcoidosis is exceptional in this age group and seldom suspected when the neurologic symptoms are present. The authors report a pediatric patient with systemic sarcoidosis who developed a severe but silent neurologic involvement. Numerous masslike lesions were discovered on systematic cranial magnetic resonance imaging. The authors recommend a complete screening of extrapulmonary manifestations in children with sarcoidosis. The proper management of patients with incidentally discovered neurosarcoidosis has yet to be established.
