Abstract
The calcar avis indents the medial wall of the occipital horn of the lateral ventricle and, when prominent, may be seen on an ultrasonogram (especially one obtained through the posterior fontanel). It should be recognized as a normal variant and not be mistaken for an abnormal mass or resolving blood clot.
摘要
禽距使侧脑室枕角的内侧壁内陷，明显时可在超声检查中看到（尤其是通过后囟获得的超声图像）。应将其视为正常变异，而不应误认为是异常肿块或正在消散的血凝块。
