"Congenital" tumors that cause hydrocephalus early in life are large masses and can easily be detected by ultrasound. CT is better for differentiating among the diverse types of mass lesions and is performed after screening by ultrasound. In our experience, ultrasound has proved successful for visualizing all of the intracranial cysts except those in the temporal fossa. Most patients with temporal fossa cysts, however, have other symptoms and signs, such as asymmetric head and seizures that lead to further investigation and correct diagnosis despite the failure to identify the temporal cysts by ultrasound. With newer and better ultrasound equipment, the detection of temporal fossa arachnoid cysts will be improved. We believe that neurosonography should be the initial tool for investigating infants and neonates who present with large heads or abnormally rapid increase in head size.
在生命早期导致脑积水的“先天性”肿瘤是大肿块，可通过超声轻松检测到。CT在区分各种类型的肿块病变方面更具优势，在超声筛查后进行。根据我们的经验，超声已被证明能成功显示除颞窝囊肿外的所有颅内囊肿。然而，大多数患有颞窝囊肿的患者有其他症状和体征，如头部不对称和癫痫发作，尽管超声未能识别出颞窝囊肿，但这些症状和体征仍会促使进一步检查并做出正确诊断。随着更新更好的超声设备出现，颞窝蛛网膜囊肿的检测将会得到改善。我们认为，神经超声检查应作为对出现大头或头围异常快速增加的婴儿和新生儿进行检查的初始工具。
