What is a extradural abscess?

An extradural abscess is a rare but serious infection that occurs in the space between the dura mater (the outermost layer of the meninges) and the skull. It is most commonly caused by bacteria that spread from a nearby infection, such as a mastoid infection or sinusitis. Extradural abscesses can also occur after head injuries or neurosurgery.

Symptoms of an extradural abscess can include:

* Severe headache

* Fever

* Stiff neck

* Nausea and vomiting

* Confusion

* Seizures

* Coma

If you experience any of these symptoms, it is important to seek medical attention immediately. Extradural abscesses can be life-threatening if not treated promptly.

Treatment for an extradural abscess typically involves surgery to drain the abscess and remove any infected tissue. Antibiotics will also be given to kill the bacteria. In some cases, surgery may be followed by a course of radiation therapy.

The prognosis for an extradural abscess depends on the severity of the infection and the timeliness of treatment. With early diagnosis and treatment, most people recover fully. However, extradural abscesses can be fatal if not treated promptly.
