Quizplus · Accepted Answer

A lentiform shaped hyperdensity on CT examination located between the dura and surrounding calvarium is characteristic of an epidural hematoma, which is a collection of blood between the skull and the dura mater. This is distinguished from a subdural hematoma, which is located between the dura mater and the arachnoid mater, and a subarachnoid hematoma, which is located within the subarachnoid space. A cortical contusion is a bruise to the surface of the brain and would not appear as a hyperdensity on CT.
