Pediatric hydrocephalus is a neurological condition characterized by an abnormal accumulation of cerebrospinal fluid (CSF) within the brain’s ventricles. This can result in increased intracranial pressure and a range of symptoms. Dr. Tim Vogel, a distinguished pediatric neurosurgeon, leads our efforts at Pediatric Neurosurgeons of New Jersey in providing expert evaluation and treatment for children and families facing hydrocephalus. Dr. Vogel is a developmental neuroscientist that has studied the early genetic and cellular events responsible for the onset of hydrocephalus. His research has been funded by the Hydrocephalus Association and the National Institutes of Health (NIH).
The Anatomy
The human brain is enveloped by a protective layer called the meninges and is bathed in cerebrospinal fluid. This clear fluid plays a crucial role in cushioning the brain, providing essential nutrients, and removing waste products. Within the brain are interconnected cavities known as ventricles that produce and circulate CSF. These ventricles are responsible for maintaining a delicate balance of CSF volume.
Cerebrospinal fluid is produced within the brain’s ventricles and circulates through a system of pathways, ultimately being absorbed into the bloodstream. Any disruption in this circulation, such as blockages or overproduction, can lead to an accumulation of CSF within the ventricles. This causes increased intracranial pressure and can result in the symptoms associated with hydrocephalus. Prompt diagnosis and treatment are essential to ensure optimal outcomes.
The Types
Pediatric Hydrocephalus
Pediatric hydrocephalus refers to cases that occur during childhood, typically after birth. It is one of the most common neurological disorders in pediatric patients. Pediatric hydrocephalus can result from congenital factors, infections, brain tumors, or head injuries. Early diagnosis and intervention are crucial to mitigate complications related to cognitive and physical development.
Neonatal Hydrocephalus
Neonatal hydrocephalus presents in the first 28 days of life, often as a congenital condition. This can be caused by various factors, including genetic abnormalities, brain malformations, or bleeding within the brain. Neonatal hydrocephalus requires prompt attention and may involve surgical interventions to alleviate intracranial pressure and prevent neurological damage.
Fetal Hydrocephalus
Fetal hydrocephalus is a rare condition that develops during pregnancy when excessive CSF accumulates within the developing fetus’s brain, typically detected through prenatal ultrasounds. Fetal hydrocephalus may be associated with genetic syndromes, neural tube defects, or other abnormalities and often necessitate management through fetal surgery or shunt placement.
The Prevalence
Hydrocephalus is the most prevalent neurological disorder in pediatric development, affecting approximately 1 in every 1,000 children. While there is no definitive cure, significant progress has been made in treatment options. Over the past 25 years, advances in medical care have reduced mortality rates associated with hydrocephalus from 54% to 5%. This highlights the importance of early diagnosis and access to specialized care for children.
Risk Factors for Pediatric Hydrocephalus:
- Congenital hydrocephalus due to developmental abnormalities in the brain or spinal cord.
- Infections during pregnancy, such as maternal rubella or mumps.
- Intraventricular hemorrhage in premature infants.
- Brain tumors or cysts that obstruct the flow of cerebrospinal fluid.
- Inflammation and blockage from infections like meningitis.
- Severe head injuries, especially those causing bleeding or swelling.
- A neural tube defect known as spina bifida.
- Previous brain surgeries or procedures.
The Symptoms:
- A rapid increase in head size, often noticeable in infancy.
- The soft spots on an infant’s head may appear tense and bulging.
- Increased fussiness, irritability, or poor feeding.
- Frequent or projectile vomiting, especially in the absence of other gastrointestinal issues.
- Downward deviation of the eyes (sunsetting sign), double vision, or blurred vision.
- Reduced body tone, poor muscle strength, and developmental delays.
- Difficulty with balance, coordination, and walking.
- Persistent headaches in older children.
- Personality changes, lethargy, or declining school performance.
The presence of these symptoms, especially in combination, necessitates prompt medical evaluation to assess the possibility of hydrocephalus. Early diagnosis and intervention are crucial for better outcomes and improved quality of life.
The Diagnosis
Diagnosing pediatric hydrocephalus involves a thorough clinical evaluation and advanced imaging techniques. Dr. Vogel and our team assess symptoms such as an enlarged head, bulging fontanelles, and developmental delays, following which imaging tests like ultrasound, CT scans, and MRIs are used to visualize the brain’s ventricles. Timely diagnosis is critical for early intervention and the development of a customized treatment plan.
The Treatment
Pediatric hydrocephalus demands prompt intervention to relieve increased intracranial pressure and prevent neurological damage. Treatment options often include surgical procedures, such as ventriculoperitoneal (VP) shunt placement or endoscopic third ventriculostomy (ETV), to divert or reabsorb excess cerebrospinal fluid. Individualized care plans may include ongoing monitoring, rehabilitation, and support services to address developmental delays or complications. Dr. Vogel and our team of pediatric neurosurgeons provide comprehensive and compassionate care for young patients.
