G06.2
Extradural and subdural abscess, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
An extradural and subdural abscess refers to a collection of pus that forms either outside the dura mater (the outermost layer of the meninges surrounding the brain and spinal cord) or between the dura mater and the arachnoid mater. This condition is a serious medical issue that requires prompt diagnosis and treatment. It can cause pressure on the brain or spinal cord, leading to neurological problems. The term 'unspecified' indicates that the specific location of the abscess—extradural or subdural—has not been clearly identified in some cases.
Causes & Symptoms
Clinical Causes: Bacterial infections, most commonly Staphylococcus aureus Spread from nearby infections such as pneumonia, sinusitis, or mastoiditis Trauma or injury that introduces bacteria into the epidural or subdural space Spread from systemic infections through the bloodstream Post-surgical or post-neurosurgical complications
Key Symptoms: Headache that worsens over time Fever and chills Neck stiffness or rigidity Nausea and vomiting Altered mental status or confusion Neurological deficits such as weakness, numbness, or difficulty speaking Seizures Changes in consciousness or alertness
Diagnostic & Treatment
Diagnosis Path: Magnetic resonance imaging (MRI) with contrast to visualize the abscess Computed tomography (CT) scan for initial assessment Blood tests to identify infection markers and causative bacteria Lumbar puncture may sometimes be performed to analyze cerebrospinal fluid, though caution is advised if a mass lesion is suspected
Treatment Protocols: Intravenous antibiotics tailored to the suspected or identified bacteria Surgical drainage or removal of the abscess to reduce pressure and remove infected material Supportive care such as pain management and monitoring neurological function Follow-up imaging to assess treatment response Management of any underlying infection sources or predisposing conditions
