Raccoon Eyes (Periorbital Ecchymosis)[edit | edit source]

Raccoon eyes, also known as panda eyes in the United Kingdom and Ireland, or periorbital ecchymosis, is a medical sign that may indicate a basal skull fracture, subgaleal hematoma, a craniotomy that ruptured the meninges, or, in rare cases, certain types of cancer.

Raccoon eyes in a patient

Description[edit | edit source]

Raccoon eyes refer to bruising around the eyes that resemble the mask-like patterns seen in raccoons. This condition arises due to bilateral hemorrhage, often as a result of facial fractures that tear the meninges, leading to bleeding from the venous sinuses into the arachnoid villi and cranial sinuses. In simpler terms, blood from a skull fracture seeps into the soft tissues around the eyes.

Associated Conditions[edit | edit source]

Raccoon eyes are commonly associated with:

Basal skull fractures
Subgaleal hematoma
Post-cranial surgery complications

In rare instances, they may also signal the presence of certain cancers.

Diagnosis and Symptoms[edit | edit source]

The appearance of raccoon eyes typically occurs within 48 to 72 hours after an injury. They may present alongside Battle's sign, which is an ecchymosis (bruising) behind the ear. These signs can sometimes be the sole indicators of a skull fracture, as the fracture may not be visible on an X-ray.

Medical Advice and Precautions[edit | edit source]

It is recommended that individuals with raccoon eyes should avoid blowing their nose or coughing vigorously to prevent further complications. Medical attention is essential for proper diagnosis and treatment.
