ICD-11 MMS 2026-01

Parkinsonism due to structural lesions

Description

Parkinsonism occurring in the setting of a demonstrable structural lesion such as subdural hematoma and brain tumours. Neuroimaging such as Magnetic Resonance Imaging is very helpful. It has to be emphasized that small brain tumours such as meningioma may be an incidental finding in cases of otherwise typical PD.
