In babies, it may be seen as a rapid increase in head size. Other symptoms may include vomiting, sleepiness, seizures, and downward pointing of the eyes. [1] Hydrocephalus can occur due to birth defects or be acquired later in life. [1] Associated birth defects include neural tube defects and those that result in aqueductal stenosis.
[5] [11] DWM is the cause of around 4.3% of cases of congenital hydrocephalus [14] and 2.5% of all cases of hydrocephalus. [ 6 ] A 2017 review found that most patients (65%) were diagnosed with either "Dandy–Walker malformation" or "Dandy–Walker syndrome", while 20% were diagnosed with "Dandy–Walker variant" and 1.1% with "mega cisterna ...
Walker–Warburg syndrome (WWS), also called Warburg syndrome, Chemke syndrome, HARD syndrome (Hydrocephalus, Agyria and Retinal Dysplasia), Pagon syndrome, cerebroocular dysgenesis (COD) or cerebroocular dysplasia-muscular dystrophy syndrome (COD-MD), [1] is a rare form of autosomal recessive congenital muscular dystrophy.

Hydrocephalus; schizencephaly; microgyria; microcephaly; Pierre-Robin syndrome; Neurofibromatosis; Often colpocephaly occurs as a result of hydrocephalus. Hydrocephalus is the accumulation of cerebrospinal fluid (CSF) in the ventricles or in the subarachnoid space over the brain. The increased pressure due to this condition dilates occipital ...
The enlarged skull of a person with hydrocephalus, which is a symptom of the excess CSF in the ventricular system. This may be caused by aqueductal stenosis, and in some cases, it is thought that hydrocephalus will cause aqueductal stenosis. Many of the signs and symptoms of aqueductal stenosis are similar to those of hydrocephalus.
A dentist who examined the upper right maxilla found with the skull determined that the skull was that of a child aged 4.5 to 5 years. The volume, however, of the interior of the Starchild skull is 1,600 cubic centimeters, which is 200 cm³ larger than the average adult's brain, and 400 cm³ larger than an adult of the same approximate size.
Many organ systems are affected by triploidy, but the central nervous system and skeleton are the most severely affected: . Common central nervous system defects seen in triploidy include holoprosencephaly, hydrocephalus (increased amount of cerebrospinal fluid within the brain), ventriculomegaly, Arnold–Chiari malformation, agenesis of the corpus callosum and neural tube defects.
CPCs are a rare cause of intermittent hydrocephalus. This is caused by a blockage of foramina within the ventricular drainage system of the central nervous system (CNS), which can lead to expansion of the ventricles, compressing the brain (the cranial cavity cannot expand to accommodate the increase in fluid volume) and possibly causing damage.
