Background：Few studies have addressed whether abnormalities in the lenticular nucleus （LN） are characteristic transcranial sonography （TCS） echo features in patients with primary *** study aimed to explore alterations in the basal ganglia in different forms of primary focal ***：A cross-sectional observational study was performed between December 2013 and December 20 1 4 in 80 patients with different forms of primary focal dystonia and 55 neurologically normal control *** was performed in patients and control *** comparisons of multiple rates were used to compare LN hyperechogenicity ratios between control and patient ***：Thirteen individuals were excluded due to poor temporal bone windows,and two subjects were excluded due to disagreement in evaluation by ***,70 patients （cervical dystonia,n =30;blepharospasm,n =30;oromandibular dystonia,n =10） and 50 normal controls were included in the final *** hyperechogenicity was observed in 51% （36/70） of patients with primary focal dystonia,compared with 12% （6/50） of controls （P 〈 0.001）.Substantia nigra hyperechogenicity did not differ between the two *** hyperechogenicity was observed in 73% （22/30） of patients with cervical dystonia,a greater prevalence than in patients withblepharospasm （33%,10/30,P =0.002） and oromandibular dystonia （40%,4/10,P =0.126）.LN hyperechogenicity was more frequently observed in patients with cervical dystonia compared with controls （73% vs.12%,P 〈 0.001）;however,no significant difference was detected in patients with blepharospasm （33% vs.12%,P =0.021） or oromandibular dystonia （40% vs.12%,P =0.088）.Conclusions：LN hyperechogenicity is more frequently observed in patients with primary focal dystonia than in *** does not appear to be a characteristic TCS echo feature in patients with blepharospasm or oromandibular dystonia.
