Most of the subventricular cysts will disappear on their own in the later stage, and this will not have any effect on the body. If the cysts are relatively large and are not self-absorbed, they may lead to the compression of intracranial structures, which will have some effect on the growth and intellectual development of the infant. Subventricular cysts belong to the more common craniocerebral injuries in newborns, closely related to congenital development, preterm birth, intrauterine distress, intraventricular hemorrhage, most of which are found during physical examination for ultrasonography. Generally small within 1-2cm, they can be self-absorbed with growth and development, and will not affect the infant’s intelligence. Even larger subventricular cysts may disappear spontaneously within 6 months, and serious neurodevelopmental complications do not usually occur. On the contrary, if the cyst is expanding and not absorbed, it may lead to compression of the infant’s intracranial structures, which may affect the infant’s growth and intellectual development, and may be manifested as a temporary backwardness in physical development and a temporary backwardness in intellectual development in the first year of life, which may need to be alleviated with the help of surgery or drainage.
