Idiopathic Parkinson's disease combined with multiple system atrophy. A clinicopathological report.

Mov Disord. 1991; 6(4):342-6.MD

The clinical and postmortem findings of a patient with Lewy body pathology combined with multiple-system atrophy are described. When alive the patient was diagnosed as having Parkinson's disease. Pathological examination found evidence of striatonigral and olivopontocerebellar degeneration, together with Lewy bodies at a number of sites characteristic for idiopathic Parkinson's disease. Taken together, the clinical history and histological findings support the coexistence of two disease processes.
