P91.1

Clinical Causes: Intraventricular hemorrhage occurring soon after birth Birth complications leading to brain injury Infections such as neonatal meningitis or ventriculitis Periventricular leukomalacia (white matter damage) Hypoxic-ischemic events causing brain tissue injury Premature birth with immature brain development Trauma during delivery

Key Symptoms: Delayed motor development or muscle tone abnormalities Seizures or abnormal EEG patterns Poor feeding or feeding difficulties Abnormal muscle stiffness or floppiness Poor responsiveness or lethargy Potential signs of increased intracranial pressure, such as vomiting or irritability

Diagnosis Path: The diagnosis of acquired periventricular cysts typically involves a combination of clinical assessment and imaging studies. Cranial ultrasound is often the first step, especially in newborns and infants, due to its safety and ease of use. Magnetic resonance imaging (MRI) provides detailed visualization of the brain tissue and cysts, helping to assess their size, number, and impact on surrounding structures. Additional tests may include neurological evaluations and monitoring of developmental milestones to understand the extent of brain involvement.

Treatment Protocols: Antiepileptic medications for seizure control Physiotherapy, occupational therapy, and speech therapy to promote motor and cognitive development Monitoring and management of intracranial pressure if increased Addressing underlying causes, such as infections or hemorrhages Regular neurological and developmental assessments to tailor supportive care
