Post-Traumatic Bifrontoparietal Extradural Hematoma with Superior Sagittal Sinus Detachment: A Case Report and Review of the Literature.

Objective: To present, to our knowledge, the first case of a single bilateral extradural hematoma due to superior sagittal sinus detachment that was treated conservatively with an excellent outcome.

Methods: Bilateral extradural hematomas are a rare condition, accounting for only 2%-5% of all extradural hematomas. They can be either 2 distinct hematomas on either side or 1 single bilateral hematoma mostly due to sagittal sinus injury, with the latter being the most rare owing to the firm attachment of the sinus to its subperiosteal loggia.
