Benign macrocrania of infancy is a more common condition in which a baby can have mild ventriculomegaly and a large head, but not hydrocephalus. Although this condition causes the head to grow too fast, the baby is otherwise well, and the condition is self-limiting. It does not require treatment. Ventriculomegaly symptoms, causes, diagnosis, and treatment information for Ventriculomegaly (Hydrocephalus) with alternative diagnoses, full-text book chapters, misdiagnosis, research treatments, prevention, and prognosis.
Ventriculomegaly, also known as hydrocephalus, is a condition in which the CSF-filled structures within the brain become larger than normal. As a result, the large ventricles can inhibit the proper development of the brain. Sometimes ventriculomegaly is associated with developmental problems of the fetal spine called neural tube defects or spina bifida. Isolated mild ventriculomegaly may be expected to remain unchanged in 60 percent of cases and to resolve in one-third of cases. The ventricles can be expected to enlarge in approximately 8 percent of fetuses. Isolated ventriculomegaly greater than or equal to 12 mm is associated with normal neurodevelopment in approximately 77% of cases.
