Parkinsonism due to subdural hematoma. Case report

The authors describe the case of a 38-year-old woman who presented with parkinsonian syndrome associated with chronic subdural hematoma. Gradual disappearance of the symptomatology followed removal of the hematoma. Chronic subdural hematoma may in rare instances cause a parkinsonian syndrome, probably by a pressure effect on basal ganglia structures or by altering the function of neurotransmitters.
