Pediatric-specific data on PTH remain limited; however, recent studies suggest that younger age - particularly under five years at injury - as well as injury severity are the two strongest predictors of PTH development. Clinically, PTH may present acutely with neurological deterioration or chronically with delayed recovery and neurodevelopmental regression. Early recognition is critical, as untreated PTH can lead to lifelong neurological dysfunction and even death, yet diagnosis is often delayed by symptom overlap with other posttraumatic conditions and difficulties in distinguishing true hydrocephalus from ventriculomegaly. Management is primarily surgical and centers on cerebrospinal fluid (CSF) diversion, most commonly with external ventricular drainage (EVD) in the acute phase and permanent shunting or ventriculostomy in select cases. Despite timely intervention, long-term morbidity remains substantial, underscoring the importance of prevention, early detection, and multidisciplinary follow-up.
