Spontaneous evacuation of hyperacute extradural hematoma: two illustrative case reports

Area of Science:

• Neurosurgery
• Pediatric Traumatology
• Radiology

Background:

• Extradural hematoma (EDH) is a collection of blood between the dura mater and the skull.
• Spontaneous evacuation or resolution of EDH through a skull fracture is an exceptionally rare event.
• Previous literature reports only 14 cases globally, with five in pediatric patients.

Observation:

• The authors present two pediatric cases of acute EDH.
• Both cases involved spontaneous evacuation of the hematoma through distinct types of skull fractures.
• One fracture was an elevated fracture, a less commonly reported type in EDH spontaneous resolution.

Findings:

• The study clarifies the precise definitions and appropriate usage of "spontaneous evacuation" versus "spontaneous resolution" in the context of EDH.
• Detailed radiological and clinical data from the two cases are presented.
• This adds to the scarce existing literature on spontaneous EDH drainage in children.

Implications:

• Understanding spontaneous EDH evacuation mechanisms can refine clinical management strategies for pediatric head injuries.
• The findings may influence diagnostic and treatment protocols for acute EDH in children.
• Further research into the biomechanics of skull fractures facilitating EDH drainage is warranted.
