A normoechogenic substantia nigra (SN) is a typical finding in transcranial sonography in patients with progressive supranuclear palsy (PSP), whereas in patients with Parkinson's disease a hyperechogenic SN is characteristic. A recent classification scheme recommends the differentiation of PSP patients into those with Richardson's syndrome (RS) and those with PSP-Parkinsonism (PSP-P). We investigated 34 PSP patients (27 RS, 7 PSP-P) with ultrasound of the substantia nigra in search of differentiations in the two groups. We found that most of the PSP-P patients, according to recently published criteria, had a hyperechogenic SN (6 of 7): right (cm(2)) median 0.22, 25% percentile 0.21 and 75% percentile 0.36 (cm(2)); left (cm(2)) median 0.21, 25% percentile 0.20 and 75% percentile 0.30 and a normal third ventricle (mean mm) +/-SD: 7.1 +/- 2.43). In RS patients a normoechogenic SN (26 of 27) and an enlarged third ventricle (mean mm) +/-SD: 10.3 +/- 2.41) was found. These differences may elucidate the pathological differences of RS and PSP-P.
黑质回声正常是进行性核上性麻痹(transcranial sonography)患者的典型表现,而帕金森病患者的黑质表现为高回声。最近的分类方案建议将进行性核上性麻痹患者分为Richardson 综合征(Richardson's syndrome)和帕金森病型进行性核上性麻痹(parkinsonism PSP-P)。我们对 34 例进行性核上性麻痹患者(27 例 Richardson 综合征,7 例帕金森病型进行性核上性麻痹)进行了黑质超声检查,以寻找两组之间的差异。我们发现,根据最近公布的标准,大多数帕金森病型进行性核上性麻痹患者的黑质回声较高(7 例中的 6 例):右侧(cm²)中位数为 0.22,25%位数为 0.21,75%位数为 0.36(cm²);左侧(cm²)中位数为 0.21,25%位数为 0.20,75%位数为 0.30,第三脑室正常(mean mm)+/-SD:7.1 +/- 2.43)。Richardson 综合征患者的黑质回声正常(27 例中的 26 例),第三脑室扩大(mean mm)+/-SD:10.3 +/- 2.41)。这些差异可能阐明了 Richardson 综合征和帕金森病型进行性核上性麻痹的病理差异。
