An epidural hematoma is a type of brain injury that occurs when blood collects between the outer layer of the brain, called the dura mater, and the skull. This condition often results from a head injury, such as a fall or car accident, where a blood vessel is torn. Symptoms may include headache, confusion, dizziness, and loss of consciousness. If left untreated, an epidural hematoma can lead to increased pressure on the brain, which can be life-threatening. Diagnosis typically involves imaging tests like a CT scan or MRI. Treatment often requires surgical intervention to remove the accumulated blood and relieve pressure.
