Study Notes
Causes of Pediatric Hydrocephalus
- Genetic disorders: e.g. aqueductal stenosis, X-linked hydrocephalus, Dandy-Walker syndrome
- Infections: e.g. meningitis, ventriculitis, TORCH infections (toxoplasmosis, rubella, cytomegalovirus, herpes simplex)
- Bleeding: e.g. intraventricular hemorrhage (IVH), subarachnoid hemorrhage
- Tumors: e.g. brain tumors, spinal cord tumors
- Trauma: e.g. head trauma, spinal cord injury
- Other: e.g. arachnoid cysts, vein of Galen malformations
Symptoms of Pediatric Hydrocephalus
- Increased head circumference: rapid growth in head size, especially in infants
- Vomiting: often projectile
- Irritability: fussiness, restlessness
- Lethargy: excessive sleepiness
- Seizures: rare, but can occur in some cases
- Developmental delays: delayed milestones, such as sitting, standing, or walking
- Vision problems: e.g. strabismus, nystagmus
- Other: e.g. poor feeding, sleep disturbances
Diagnosis of Pediatric Hydrocephalus
- Imaging studies: e.g. ultrasound, CT, MRI, to visualize ventricles and brain structures
- Physical examination: e.g. measurement of head circumference, assessment of fontanelles
- Neurological examination: e.g. assessment of reflexes, tone, and developmental milestones
- Laboratory tests: e.g. blood tests to rule out infections or other underlying conditions
Treatment Options for Pediatric Hydrocephalus
- Shunt placement: surgical insertion of a shunt to drain excess cerebrospinal fluid (CSF) from the brain
- Endoscopic third ventriculostomy (ETV): minimally invasive procedure to create a hole in the floor of the third ventricle to allow CSF to flow
- Ventriculoperitoneal (VP) shunt: most common type of shunt, drains CSF from the ventricles to the abdomen
- Ventriculoatrial (VA) shunt: drains CSF from the ventricles to the heart
- Other: e.g. repeated lumbar punctures, medications to reduce CSF production
Causes of Pediatric Hydrocephalus
- Aqueductal stenosis, X-linked hydrocephalus, and Dandy-Walker syndrome are genetic disorders that can cause pediatric hydrocephalus.
- Meningitis, ventriculitis, and TORCH infections are types of infections that can lead to pediatric hydrocephalus.
- Intraventricular hemorrhage (IVH) and subarachnoid hemorrhage are types of bleeding that can cause pediatric hydrocephalus.
- Brain tumors and spinal cord tumors can cause pediatric hydrocephalus.
- Head trauma and spinal cord injury are types of trauma that can lead to pediatric hydrocephalus.
- Arachnoid cysts and vein of Galen malformations are other causes of pediatric hydrocephalus.
Symptoms of Pediatric Hydrocephalus
- Rapid growth in head size, especially in infants, can be a sign of pediatric hydrocephalus.
- Projectile vomiting is a common symptom of pediatric hydrocephalus.
- Fussiness and restlessness are indicative of irritability in pediatric hydrocephalus patients.
- Excessive sleepiness is a symptom of pediatric hydrocephalus.
- Seizures can occur in some cases of pediatric hydrocephalus.
- Delayed milestones, such as sitting, standing, or walking, are signs of developmental delays in pediatric hydrocephalus.
- Strabismus and nystagmus are vision problems associated with pediatric hydrocephalus.
- Poor feeding and sleep disturbances are other symptoms of pediatric hydrocephalus.
Diagnosis of Pediatric Hydrocephalus
- Ultrasound, CT, and MRI are imaging studies used to visualize ventricles and brain structures.
- Measurement of head circumference and assessment of fontanelles are part of a physical examination.
- Assessment of reflexes, tone, and developmental milestones are components of a neurological examination.
- Blood tests are used to rule out infections or other underlying conditions.
