Abstract

Ultrasonography of the thigh and calf was performed in 24 children who had primary neuromuscular disease and in 20 healthy children. The ultrasound image was clearly abnormal in all patients with progressive muscular dystrophy, and in the majority of children with benign myopathic disorders; the principal changes were increased muscular echogenicity and increased attenuation of ultrasound with a reduced bone surface echo. In 13 patients, the ultrasound findings were correlated with pathologic changes seen in muscle biopsy specimens: a clear correlation (r = .85) was found. Muscular dystrophies had a higher score of abnormal ultrasonographic and microscopic findings, while the more benign muscular diseases had a lower score.

摘要

对24名患有原发性神经肌肉疾病的儿童和20名健康儿童进行了大腿和小腿的超声检查。在所有进行性肌营养不良患者以及大多数患有良性肌病的儿童中,超声图像明显异常;主要变化为肌肉回声增强、超声衰减增加以及骨表面回声减弱。在13名患者中,超声检查结果与肌肉活检标本中所见的病理变化相关:发现了明显的相关性(r = 0.85)。肌营养不良症在超声和显微镜检查异常结果方面得分较高,而良性肌肉疾病得分较低。
