Clinical and structural neuroimaging data were reviewed by the investigators to evaluate the etiology of dystonia, specifically to identify cases of secondary dystonia caused by structural brain abnormalities.\nResults: 365 patients with cervical dystonia without other movement disorders with presumed idiopathic or uncertain etiology prior to brain imaging were identified. 282 (77.3%) were scanned using head MRI or CT. Acquired brain lesions were identified in nine (2.5% of all patients) and were significantly more common in patients with vs. without (i.e. isolated) other neurological features (P &lt; 0.001). Lesions in patients with other neurological features were considered likely (n = 4) or possibly (n = 2) causal, but all lesions in patients with isolated cervical dystonia (n = 3) were considered incidental. None of the patients showed signs of progressive neurodegeneration.\nConclusions: Routine neuroimaging is not necessary in patients with adult-onset isolated cervical dystonia.\nHighlights\nStudies investigating the need of structural neuroimaging in isolated, adult-onset cervical dystonia are scarce and opinions on this issue are divided among experts.\nIn this study, we reviewed clinical and imaging data of all patients with cervical dystonia with presumed idiopathic or uncertain etiology prior to brain imaging treated at a regional tertiary care hospital between 1996\u20132022 to investigate the yield of structural brain imaging in these patients.\nOf the included 365 patients, none showed evidence of progressive neurodegeneration underlying the symptoms and only six (1.6%) showed acquired brain lesions that were considered possibly or likely causal for cervical dystonia.\nAll the six patients with possible or likely lesion-induced cervical dystonia showed cervical dystonia combined with other neurological features, indicating that routine neuroimaging is not needed in isolated, adult-onset cervical dystonia.<\/jats:p>","DOI":"10.5334\/tohm.1049","type":"journal-article","created":{"date-parts":[[2025,8,6]],"date-time":"2025-08-06T11:02:31Z","timestamp":1754478151000},"page":"36","source":"Crossref","is-referenced-by-count":1,"title":["Is
