What is the normal upper limit for the size of the lateral ventricle?

The normal upper limit for the size of the lateral ventricle is typically considered to be 10mm. In pediatric patients, an enlarged lateral ventricle can indicate conditions such as hydrocephalus, which is an accumulation of cerebrospinal fluid that can cause increased intracranial pressure. Recognizing a normal upper limit helps practitioners assess ventricular size accurately during diagnostic studies like ultrasound or MRI.

When considering the typical measurements of lateral ventricles, values exceeding the 10mm threshold may warrant further investigation, while measurements at or below this value are generally accepted as within the normal range for pediatric populations. Understanding these benchmarks is crucial for sonographers, as it can guide further assessments and interventions in pediatric patients.
