Acute hydrocephalus triggered by isolated traumatic subarachnoid hemorrhage in the posterior fossa following mandibular fracture in a toddler: a rare case report.

INTRODUCTION

Facial bone fractures triggered by low-height falls are rare in toddlers, while severe intracranial injuries resulting from minor trauma are extremely rare.

CASE

Herein, we report the case of a 2-year-old girl who fell from a baby chair, striking her chin, who rapidly developed impaired consciousness 3 h later. The patient subsequently presented with a mandibular fracture and acute obstructive hydrocephalus due to a traumatic isolated subarachnoid hemorrhage in the posterior cranial fossa. She was successfully treated with ventricular drainage, which achieved a favorable outcome.

CONCLUSION

Maxillofacial trauma and head injuries are closely associated. Even in minor cases of maxillofacial trauma, vigilant monitoring and prompt intervention are crucial to prevent fatal outcomes in toddlers.
