ABRAMS LANDAU clients ask, “Why can’t the doctors see a brain injury after a crash ?”
by a layer of fatty tissue. The inner underside of the dura is applied to a much thinner, transparent membrane, the arachnoid, which overlies the brain and subarachnoid space. This interface is easily separated, forming the subdural space. The subdural space is referred to as a “potential space” because a space is not generally created unless a subdural hematoma or another space occupying mass is formed. (From the Shaken Baby Syndrome Defense site, www.sbsdefense.com /Subdurals.htm)
When a subdural hematoma forms, it is generally an indicator of a broken vein on the underlying surface of the brain. Veins draining the surface of the brain pass through the subarachnoid space and then the dura on their way into the sagittal sinus and other intradural venous sinuses that carry the venous blood eventually to the jugular system. If one or more of these veins that “bridge” the dura are injured, bleeding occurs into the subdural “space,” causing a subdural hematoma (clot). Clots, active bleeding and tears in membranes are often “invisible” to standard x-rays, as they are injuries to “soft tissues” that do not show up on the x-ray film according to brain injury lawyer Doug Landau, of ABRAMS LANDAU, Ltd.
