What is a falcine subdural hematoma?

Falcine Subdural: A subdural hematoma is a collection of blood between the surface of the brain and the dura mater. A falcine subdural hematoma is located along the falx, the dural tissue that separates the two cerebral hemispheres. It is most commonly due to head trauma but may be seen in ruptured cerebral aneurysm.

Falx Hemorrhage: A hemorrhage between the two sides of the brain (hemispheres) along the falx. The falx is a membrane that extends down from the skull and helps protect brain.

SDH: A subdural hematoma typically occurs from bridging cortical veins being torn causing blood to accumulate on the surface of the brain under the dural covering of the brain. Trauma is the most common cause. In the elderly, even relatively minor head trauma can cause a sdh. A falcine sdh is located along the midline structure called the falx.
