Racoon Eyes

Raccoon eyes

Raccoon eyes, also known as panda eyes or periorbital ecchymosis, is a sign of basilar skull fracture or subgaleal hematoma, a craniotomy that ruptured the meninges, or (rarely) certain cancers. Bilateral hemorrhage occurs when damage at the time of a facial fracture tears the meninges and causes the venous sinuses to bleed into the arachnoid villi and the cranial sinuses. In lay terms, blood from skull fracture seeps into the soft tissue around the eyes. Raccoon eyes may be accompanied by Battle's sign, an ecchymosis behind the ear. These signs may be the only sign of a skull fracture, as it may not show on an X-ray. They normally appear between 48 and 72 hours after the injury. It is recommended that the patient not blow their nose, cough vigorously, or strain, to prevent further tearing of the meninges.

Raccoon

The raccoon, sometimes called the North American, northern or common raccoon to distinguish it from other species of raccoon, is a mammal native to North America. It is the largest of the procyonid family, having a body length of 40 to 70 cm, and a body weight of 5 to 26 kg. Its grayish coat mostly consists of dense underfur, which insulates it against cold weather. The animal's most distinctive features include its extremely dexterous front paws, its facial mask, and its ringed tail, which are common themes in the mythologies of the Indigenous peoples of the Americas surrounding the species. The raccoon is noted for its intelligence, and studies show that it can remember the solution to tasks for at least three years. It is usually nocturnal and omnivorous, eating about 40% invertebrates, 33% plants, and 27% vertebrates.
