Widening of the ventricles refers to widening of the lateral ventricles. Infants with mild or moderate widening of the lateral ventricles are mostly asymptomatic; severe widening is often characterized by poorer motor coordination, increased muscle tone, and increased head circumference.
Widening of lateral ventricles in infants is the result of poor development of neutral brain structures, usually caused by brain occupation, chromosomal abnormality or viral infection. The normal range of the diameter of the lateral ventricle in infants is <10 mm, and a lateral ventricle width of ≥10 mm is generally regarded as the clinical criterion for widening of the lateral ventricle.
Lateral ventricle diameter of (10-12) mm is mildly widened and asymptomatic, and generally does not affect intelligence; diameter of (12-15) mm is moderately widened and asymptomatic, and regular checkups are the mainstay; diameter of more than 15 mm is severely widened, which may show poor motor coordination, increased muscle tone, increased head circumference, bulging fontanel, abnormal crying, vomiting, etc.; may cause abnormal convulsions, tremors, etc.
Parents are advised to bring their children to regular hospitals regularly for comprehensive examination, to clarify the specific causes of the disease, and to carry out active treatment.
