Gaucher's disease: rare presentation of a rare disease.

Gaucher's disease is a rare lysosymal storage disorder characterized by deposition of glucocerebroside in cells of the macrophage monocyte system. Gaucher's disease has 3 types-non-neuronopathic (type I), acute neuronopathic (type II), and chronic neuronopathic (type III). It generally presents with delayed milestones, seizures, bony deformities, or massive organomegaly. The acute neuronoapthic variety is the rarer type that predominantly presents with neurological features. The authors present a case of the acute neuronopathic variety of Gaucher's disease where the child presented with only abnormal head position.
