Intracranial epidural abscess

Intracranial epidural abscess represents loculated infection between the skull and the outermost layer of the cranial meninges, the dura mater. It is a severe complication of pericranial infection, particularly sinusitis, and may also develop after cranial trauma or neurosurgical procedures. Symptoms include fever, focal pain, and sometimes subcutaneous swelling over the affected area indicating a subperiosteal abscess (Pott’s puffy tumor). It can spread inward to cause intracranial subdural empyema, meningitis, brain abscess, or septic venous thrombophlebitis, which are potentially life-threatening.
