title: The diverse neurological features of Niemann-Pick disease type C: a report of two cases.
abstract: Two cases of Niemann-Pick disease type C are described in order to illustrate the variable neurological features of this rare condition. One presented with a predominantly akinetic-rigid syndrome at the age of 5 years. The second developed progressive ataxia, accompanied by a vertical gaze palsy, when she was 13. Neither patient had hepatosplenomegaly; the diagnosis of Niemann-Pick disease type C was based on finding foamy storage cells in bone marrow aspirates.
