Bilateral Subacute Subdural Hematoma

• These are bilateral and are isodense with the brain because of gradual loss of density of blood.
• On close exam you see that the sulcal markings do not reach the surface of the skull, due to the intervening subdural collection.
• Arrowheads point to subdurals separating the brain surface markings from the skull.
• There is no midline shift.
