Periventricular leukomalacia (PVL) diagnosis confirmed in this neonate born at [gestational age] weeks.  Presenting symptoms include [list symptoms e.g., hypotonia, spasticity, developmental delays, seizures].  Cranial ultrasound demonstrates [describe findings e.g., echogenicity, cystic changes, ventricular dilation] in the periventricular white matter, consistent with PVL.  Differential diagnoses considered included intraventricular hemorrhage, hypoxic-ischemic encephalopathy, and congenital infections, but were ruled out based on clinical presentation and imaging findings.  The patient's history is significant for [list relevant prenatal, perinatal, and postnatal risk factors e.g., premature birth, chorioamnionitis, low birth weight, respiratory distress syndrome].  Neurological examination reveals [describe neurological findings e.g., altered muscle tone, deep tendon reflexes, presence of clonus].  Given the confirmed PVL diagnosis, the patient will be closely monitored for developmental milestones and potential complications such as cerebral palsy, cognitive impairment, and epilepsy.  Treatment plan includes early intervention services focusing on physical therapy, occupational therapy, and speech therapy.  Regular follow-up with neurology and developmental pediatrics is scheduled to assess developmental progress and adjust interventions as needed.  ICD-10 code P91.6 (Periventricular leukomalacia of infancy) assigned.  Prognosis discussed with parents, emphasizing the importance of ongoing support and multidisciplinary care.
