Hydrocephalus occurs when cerebrospinal fluid builds up within the brain and causes the ventricles to enlarge. In infants and children, increased pressure can interfere with brain function and development. Depending on the cause and severity, a child may experience neurological impairment, developmental delays, seizures, movement limitations, or other long-term concerns.
When a child is diagnosed with hydrocephalus, families may have questions about whether prenatal findings, symptoms after birth, or treatment decisions affected the child’s condition. Hydrocephalus can involve complex medical circumstances that require careful review of prenatal findings, newborn care, and treatment decisions.

Cerebrospinal fluid, commonly called CSF, normally circulates through spaces within and around the brain and spinal cord. It helps cushion the central nervous system and is continuously produced and reabsorbed by the body.
Hydrocephalus develops when this fluid accumulates abnormally. The National Institute of Neurological Disorders and Stroke explains that excess CSF causes the brain’s ventricles to widen and can place harmful pressure on brain tissue.
Hydrocephalus may be present at birth or develop later.
Possible causes in babies can include:
Hydrocephalus can also develop after birth because of infection, bleeding, or other neurological conditions.
Signs in an infant may include:
These symptoms require careful medical evaluation and appropriate diagnostic testing to determine whether hydrocephalus is present.
A historic CDC/NCHS national vital-statistics report documented 858 cases of hydrocephalus among 3,009,144 births in the population analyzed, or roughly 29.7 cases per 100,000 births in that dataset.
A hydrocephalus case requires careful review of medical records, diagnostic decisions, treatment timelines, and the impact of the condition on the child.
A medical malpractice claim generally requires evidence that a healthcare provider failed to meet the accepted standard of care and that this failure caused or contributed to additional harm.
Depending on the circumstances, a legal investigation may examine whether providers:
The distinction between the underlying condition and additional preventable harm can be especially important.
When hydrocephalus is present, the medical review may examine whether providers identified concerns, communicated findings, and provided appropriate follow-up and treatment.
Establishing causation requires review of the timing of symptoms, diagnostic decisions, treatment provided, and resulting neurological effects. The medical record must support the conclusion that earlier recognition or treatment probably would have improved the outcome.
Some forms of hydrocephalus or ventricular enlargement can be detected through prenatal imaging.
Ultrasound examinations may reveal enlargement of the ventricles or other structural findings involving the developing brain. Depending on the findings, gestational age, and other medical circumstances, additional imaging or follow-up may be recommended.
Potentially relevant prenatal records can include:
Abnormal prenatal imaging findings may require additional evaluation, follow-up imaging, or referral depending on the circumstances.
If a legal question arises, the issue is whether providers appropriately recognized, communicated, monitored, and responded to the available findings.
For example, an investigation may examine whether a concerning measurement was documented but not followed, whether additional imaging was medically indicated, or whether the family was referred for further evaluation when appropriate.
Not every case is identifiable prenatally.
After birth, healthcare providers may monitor a baby’s head circumference, neurological development, feeding, alertness, muscle tone, and other clinical signs.
The NINDS identifies rapid head growth, an unusually large head, and bulging of the fontanel among possible signs of hydrocephalus in infants.
A legal review may become relevant when there is a pattern of concerning findings that parents believe was not appropriately investigated.
For example:
A pattern of symptoms, examination findings, and diagnostic results may provide important information when evaluating whether additional assessment was needed.
Brain imaging is generally central to diagnosis. Depending on the child’s age and circumstances, providers may use ultrasound, MRI, CT, or other testing to evaluate the ventricles and surrounding brain tissue.
A potential claim generally requires evidence of both a departure from the accepted standard of care and causation.
Questions may include whether providers:
The medical review focuses on when hydrocephalus developed, how it was identified, and whether healthcare providers responded appropriately.
The investigation may examine whether earlier recognition, monitoring, or treatment could have reduced the child’s neurological harm. The legal issue may instead be whether appropriate diagnosis or treatment could have prevented some of the resulting neurological damage.
The evidence must evaluate how the timing of diagnosis and treatment affected the child’s neurological outcome.
The effects of hydrocephalus vary significantly.
Some children respond well to treatment and experience relatively limited impairment. Others may have lasting neurological or developmental concerns, particularly when the underlying condition is severe or brain tissue has been affected.
Potential long-term concerns can include:
A child may require:
These needs may change over time.
When delayed diagnosis or treatment contributes to permanent neurological harm, evaluating damages may require consideration of future medical treatment, rehabilitation, equipment, caregiving, educational needs, and reduced future earning capacity.
For families, however, understanding what happened often comes first.
Arizona law imposes time limits on medical malpractice actions.
Under A.R.S. § 12-542, an action for personal injury, including a cause of action for medical malpractice, generally must be commenced within two years after the cause of action accrues.
Claims involving children can require additional analysis under Arizona law, and claims belonging to parents may differ from claims belonging to the child.
Families should therefore obtain guidance based on their specific circumstances rather than rely on a general filing period.
Earlier investigation may also make it easier to preserve medical records and reconstruct when abnormal symptoms or imaging findings first appeared.
If your child developed hydrocephalus and you have questions about prenatal, newborn, or pediatric care provided in Scottsdale, Snyder & Wenner can review the medical evidence and review the medical timeline, evaluate the evidence, and help families understand their legal options.
Hydrocephalus is an abnormal buildup of cerebrospinal fluid within the brain. The excess fluid can enlarge the ventricles and place pressure on surrounding brain tissue.
Yes. Some children have congenital hydrocephalus caused by developmental or genetic conditions. Others develop hydrocephalus after birth because of bleeding, infection, or other neurological problems.
Possible signs include rapid head growth, an unusually large head, a bulging soft spot, vomiting, unusual sleepiness, irritability, feeding difficulties, seizures, or developmental concerns.
Some cases may be suspected through prenatal ultrasound or other imaging when enlargement of the brain’s ventricles or associated structural findings are identified. Not every case is detectable before birth.
A hydrocephalus case may involve review of prenatal imaging, newborn examinations, pediatric records, neurological findings, brain imaging, treatment records, and documentation showing how healthcare providers responded to symptoms and diagnostic findings.
Delayed diagnosis or treatment may affect the severity of neurological complications in some cases. Medical records can help evaluate whether earlier intervention could have changed the child’s outcome.
Relevant records can include prenatal imaging, newborn examinations, head-circumference measurements, pediatric visits, neurological findings, brain imaging, hospital records, neurosurgical documentation, and developmental evaluations.
Treatment often involves reducing excess cerebrospinal fluid and pressure. Shunt placement is one commonly used approach, although other procedures may be appropriate depending on the cause and medical circumstances.
A child may require neurological or neurosurgical monitoring, imaging, therapy, medication, developmental services, educational support, assistive equipment, or personal care depending on the extent of impairment.
Our attorneys review when abnormal findings first appeared, how healthcare providers responded, and whether earlier diagnosis or treatment probably would have changed the outcome. When appropriate, we work with qualified medical professionals to evaluate the standard of care, causation, and long-term consequences.
