Abstract
Introduction. Transcranial sonography (TCS) is a relatively new ultrasound modality which could display echogenicity of human brain tissue through the intact skull. TCS may be useful in differentiation of idiopathic Parkinson’s disease (PD) from other parkinsonian disorders. Therefore, we studied different ultrasound markers by TCS in individuals with Parkinson’s disease. Patients and Methods. We performed TCS in 44 patients with PD and 22 patients with other parkinsonian disorders. Echogenic sizes of the substantia nigra (SN) and the lentiform nuclei (LN), as well as the width of the third ventricle and the frontal horns of the lateral ventricle, were measured. We also analyzed the echogenicity of the brainstem raphe (BR). Results. An unilateral hyperechogenic SN was observed in 31 (70%) patients with PD and only in 2 patients (9%) with other parkinsonian disorders (P<0.0001). Hyperechogenicity of the LN was no observed in patients with PD; however, it was present in 7 (32%) patients with other parkinsonian disorders (P=0.0002). Diameter of third ventricle (8.6+/-2.2 mm vs. 6.9+/-1.7mm, P=0.001), right (18.5+/-2.6 mm vs. 16.5+/-2.3 mm, P=0.003) and left frontal horn of lateral ventricle (19.0+/-3.7 mm vs. 16.2+/-2.6 mm, P=0.0006) was significantly wider in patients with other parkinsonian disorders compared with patients with PD. There was no difference in presence of hypoechogenic or interrupted BR in patients with PD and patients with other parkinsonian disorders (39% vs. 27%, P=0.4). Conclusion. TCS is a promising diagnostic technique and can be very helpful in differentiating between idiopathic Parkinson’s disease and other parkinsonian disorders.
