Ventricular enlargement is a brain condition that occurs when the lateral ventricles become dilated.
Ventricular enlargement is a brain condition that occurs when the lateral ventricles become dilated. The most common definition uses a volume to brain index value derived from MRI and CT reconstruction of the lateral and third ventricles.
Enlargement of the ventricles may occur for a number of reasons, such as loss of brain volume (due to conditions such as cortical atrophy, traumatic brain injury, or cerebral vascular accident), impaired outflow, or absorption of cerebrospinal fluid from the ventricles. Often, however, there is no identifiable cause. The interventricular foramen may be congenitally malformed, or may have become obstructed by infection, hemorrhage, or rarely by tumor, which may impair the drainage of cerebrospinal fluid, and thus accumulation in the ventricles.
