Quartet of catastrophe: Bilateral epidural hematoma in both supratentorial and infratentorial compartments - A case report and a novel surgical technique to approach.

Background: Epidural hematoma (EDH) is the most common form of traumatic brain lesion in the posterior fossa. This condition is rapidly fatal if not identified and treated accordingly, due to the proximity of the brain stem. Prompt diagnosis is made by early computed tomography (CT) of the head and emergent evacuation is of utmost importance. Case Description: A 28-year-old male presented to the emergency room with complaints of headache and vomiting following a road traffic accident. CT scan revealed EDH around the transverse sinus extending into supratentorial and infratentorial compartment bilaterally. The patient was planned for emergency surgery but relatives did not give consent initially they agreed after 24 h when the patient became unconscious. A midline incision was made and a small infratentorial craniectomy with two burr holes was made bilaterally above the transverse sinus. Excellent recovery was seen following a surgical procedure. Conclusion: Posterior fossa EDH is a rare but potentially fatal entity. Bilateral extension in supratentorial and infratentorial compartments makes it a "quartet of catastrophe." Prompt diagnosis and emergent evacuation lead to excellent recovery. Two burr holes in supratentorial compartments and a small infratentorial craniectomy can avoid sinus injury.
