Pediatric primary intraventricular hemorrhage: A case report of isolated fourth ventricle hemorrhage in a 10-year-old boy.

Key Clinical Message: Primary intraventricular hemorrhage (PIVH) is a rare condition in pediatric patients, presenting with headache, vomiting, and altered mental status. Surgical interventions, such as external ventricular drain placement, followed by ventriculoperitoneal shunting, show promising outcomes. Further research is needed to enhance understanding and optimize management strategies for pediatric PIVH. Abstract: This case report describes a 10-year-old boy with isolated primary intraventricular hemorrhage (PIVH) in the fourth ventricle, shedding light on its clinical presentation and management challenges. The patient presented with headache, vomiting, and altered sensorium, and was subsequently diagnosed with obstructive hydrocephalus due to intraventricular bleeding. Emergency external ventricular drain (EVD) insertion was performed, followed by ventriculoperitoneal shunt placement, resulting in a favorable outcome. The etiology of PIVH in children differs from that in adults, with arteriovenous malformations, Moyamoya disease, and aneurysms being commonly implicated causes. Management strategies for pediatric PIVH are challenging due to limited research, but EVD placement and surgical interventions have shown promise.
