periorbital hematoma is 1 black eye, bilateral is 2 black eyes
differences between unilateral and bilateral networks
seroma: filled with clear serous fluid hematoma: filled with red blood cells
A Subdural Hematoma occurs when a severe acceleration to deceleration occurs leading to the veins in the subdural space tearing. An Epidural Hematoma occurs from direct trauma to the brain leading to bleeding in the meningeal artery.
A hematoma is a mass of clotted blood that forms at an injury site. A fracture hematoma is a clot resulting from a break in a blood vessel within the bone, the marrow space, the periosteum, or the surrounding tissue associated with a bone fracture.

Hematoma is blood pooled outside the blood vessel, aneurysm is a bulging of a blood vessel.
For unilateral pallidotomy, a single "burr hole" is made in the top of the skull; bilateral pallidotomy requires two holes.
An intracerebral hematoma is a collection of blood from bleeding within the brain whereas a subdural hematoma is a collection of blood from bleeding outside the brain. The brain is covered by a membrane called the meninges which consists of three layers. The outermost layer is the dura mater, the middle layer is the arachnoid mater while the innermost layer which is adjacent to the outer surface of the brain is the pia mater. A subdural hematoma is therefore more specifically a collection of blood between the dura and arachnoid layers.
A stroke occurs when blood flow to the brain is disrupted, leading to cell death. A subdural hematoma, on the other hand, is a collection of blood between the brain and its outermost covering (the dura mater), often caused by head trauma. Both can lead to neurological symptoms, but a stroke is due to a blood vessel blockage or rupture in the brain, while a subdural hematoma is blood collecting outside the brain tissue.
