Which of the following descriptors of epidural hematoma is FALSE?

The statement that describes the false characteristic of epidural hematoma pertains to its common causative factors. Generally, an epidural hematoma typically occurs due to a tear in the middle meningeal artery, which is often the result of a skull fracture, but not specifically one that traverses a venous sinus. While venous sinuses can be involved in other types of hemorrhages, such as subdural hematomas or sinus thrombosis, they are not the main consideration in the formation of an epidural hematoma.

The other descriptors accurately represent key aspects of epidural hematomas. They are indeed characterized by a biconvex shape due to the location of the hematoma between the skull and the dura mater. The phenomenon of a "lucid" interval is common, where patients may regain consciousness temporarily after the initial injury before deteriorating as the hematoma expands. Surgical intervention, such as immediate evacuation of the hematoma, is often necessary to relieve pressure on the brain and prevent serious complications, including permanent damage or death.
