Sonography has been used to evaluate 50 "asymptomatic" infants (aged from birth up to two years) with typical appearing thymus on chest X-ray. The ultrasonic features of the normal gland are described. Moreover, the contribution of ultrasound is illustrated by five cases of partially ectopic thymus and by one case of prominent gland in a teenager. Ultrasound may help in differentiating normal gland from mediastinal masses by defining echogenicity, location and extension.
超声已被用于评估50名胸部X线显示胸腺形态典型的“无症状”婴儿（年龄从出生至两岁）。描述了正常胸腺的超声特征。此外，通过5例部分异位胸腺病例和1例青少年胸腺增大病例说明了超声的作用。超声可通过确定回声性、位置和范围，有助于鉴别正常胸腺与纵隔肿块。
