A Rare Patient with Hereditary Spastic Paraparesis with Parkinsonism

Herein, we present a rare patient with hereditary spastic paraparesis (HSP) in whom significant parkinsonism was involved in the clinic. Besides, the dopamine transport single-photon emission computed tomography scan also showed decreased tracer uptake in the bilateral striatum. Via the presentation of this patient, we discuss the parkinsonian findings in patients with HSP. We think that the observations of dopaminergic neuron vulnerability in HSP patients raise the possibility that degeneration of central dopaminergic neurons may contribute to the phenotype of HSP. The documentation of these rare variants will aid to understand the unknown pathophysiology of the disease course.
