==CT==
==Overview==
Most of the time, subdural hematomas occur around the tops and sides of the [[frontal lobe|frontal]] and [[parietal lobe]]s.They also occur in the posterior [[fossa]], and near the [[falx cerebri]] and [[tentorium]].  Unlike [[epidural hematoma]]s, which cannot expand past the [[skull suture|sutures of the skull]], subdural hematomas can expand along the inside of the skull, creating a convex shape that follows the curve of the brain, stopping only at the dural reflections like the [[tentorium]] and [[falx cerebri]].


On a [[CT scan]], subdural hematomas are crescent-shaped, with a concave surface away from the skull. Subdural blood can also be seen as a layering density along the [[tentorium cerebelli]]. This can be a chronic, stable process, since the feeding system is low-pressure. In such cases, subtle signs of bleeding such as effacement of [[sulcus (anatomy)|sulci]] or medial displacement of the junction between [[gray matter]] and [[white matter]] may be apparent.  A chronic bleed can be the same density as brain tissue (called isodense to brain), meaning that it will show up on CT scan as the same shade as brain tissue, potentially obscuring the finding.
There are no CT scan findings associated with [disease name].
