Raccoon eyes, also known as panda eyes or periorbital ecchymosis, is a sign of basal skull fracture or subgaleal hematoma, a craniotomy that ruptured the meninges, or (rarely) certain cancers. [ 1 ] [ 2 ] Bilateral hemorrhage occurs when damage at the time of a facial fracture tears the meninges and causes the venous sinuses to bleed into the ...
A basilar skull fracture is a break of a bone in the base of the skull. [ 1] Symptoms may include bruising behind the ears, bruising around the eyes, or blood behind the ear drum. [ 1] A cerebrospinal fluid (CSF) leak occurs in about 20% of cases and may result in fluid leaking from the nose or ear. [ 1]
Battle's sign, also known as mastoid ecchymosis, is an indication of fracture of middle cranial fossa of the skull. These fractures may be associated with underlying brain trauma. Battle's sign consists of bruising over the mastoid process as a result of extravasation of blood along the path of the posterior auricular artery. [ 1]
Basilar fractures have characteristic signs: blood in the sinuses; cerebrospinal fluid rhinorrhea (CSF leaking from the nose) or from the ears (cerebrospinal fluid otorrhea); periorbital ecchymosis often called 'raccoon eyes' [7] (bruising of the orbits of the eyes that result from blood collecting there as it leaks from the fracture site); and ...
Bruise. A bruise, also known as a contusion, is a type of hematoma of tissue, [ 3] the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration.
Occipital bone. The occipital bone ( / ˌɒkˈsɪpɪtəl /) is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull ). It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone overlies the occipital lobes of the cerebrum. At the base of the skull in the occipital bone, there is ...
Earnhardt was the fourth NASCAR driver killed by a basilar skull fracture during an eight-month span, following Adam Petty in May 2000, Kenny Irwin Jr. in July 2000, and Tony Roper in October 2000. Earnhardt's death, seen on a live television broadcast with more than 17 million viewers, [ 3 ] was highly publicized and resulted in various safety ...
Cerebrospinal fluid rhinorrhoea ( CSF rhinorrhoea) refers to the drainage of cerebrospinal fluid through the nose ( rhinorrhoea ). It is typically caused by a basilar skull fracture, which presents complications such as infection. It may be diagnosed using brain scans (prompted based on initial symptoms), and by testing to see if discharge from ...
