This report is on the clinical details of five genetically\u2010proven CTX patients (two with and three without parkinsonism). Imaging findings using cranial magnetic resonance (MR) imaging and <jats:sup>99m<\/jats:sup>Tc\u2010TRODAT\u20101 SPECT are also shown. Clinical correlation of neuroimaging findings and clinical presentations was made. A literature review of the clinical and neuroimaging features of eight CTX patients with parkinsonism reported in the English literature is also presented. The parkinsonian features of our two cases and the other eight reported cases occurred before the age of 50 years. The MR imaging study showed variable findings, in which, besides the common diffuse cerebral and cerebellar white matter lesions shown in CTX, several focal brain lesions were also noted. Of the focal lesions, substantia nigra abnormalities were seen only in the two cases with parkinsonism. The <jats:sup>99m<\/jats:sup>Tc\u2010TRODAT\u20101 SPECT study showed different degrees of unilateral or bilateral abnormalities in the striatal binding in both visual and semiquantitative assessments. parkinsonism can be one of the neurologic presentations of CTX. Even though abnormal findings of the substantia nigra were detected in both of our CTX patients with parkinsonism, basal ganglion lesions have not been uniformly described in MR imaging findings of reported CTX patients with parkinsonism. <jats:sup>99m<\/jats:sup>Tc\u2010TRODAT\u20101 SPECT study can be of value in the detection of striatal involvement, and the study results also suggest pre\u2010synaptic dopamine neuron involvement in CTX patients with parkinsonism. \u00a9 2010 Movement Disorder
