G00-G09: Inflammatory diseases of the central nervous system

G06: Intracranial and intraspinal abscess and granuloma

Intracranial and intraspinal abscess and granuloma comprise a group of conditions characterized by inflammation and accumulation of infectious materials within the brain or spinal cord. These conditions generally develop when bacteria, fungi, or parasites infect a part of the brain or spinal cord, creating a pocket of pus (abscess) or an area of inflamed tissue (granuloma). Typical transmission routes include direct spread from a nearby infection, through the bloodstream from a distant site, or following a surgical procedure or injury. Symptoms often include headaches, neck pain, fever, and sometimes neurological problems like weakness, numbness, or changes in mental state. These conditions can progress quickly or slowly, depending on the infecting organism and the individual's immune response. Without proper treatment, they can lead to serious health consequences including permanent neurological damage or even death.
