a well-circumscribed mass composed of tuberculous granulation tissue that may occur in the cerebral hemispheres, cerebellum, brain stem, or perimeningeal spaces. multiple lesions are quite common. management of intracranial manifestations vary with lesion site. intracranial tuberculomas may be associated with seizures, focal neurologic deficits, and intracranial hypertension. spinal cord tuberculomas may be associated with localized or radicular pain, weakness, sensory loss, and incontinence. tuberculomas may arise as opportunistic infections, but also occur in immunocompetent individuals.
Patient EducationClinical
Meningitis
Meningitis is inflammation of the thin tissue that surrounds the brain and spinal cord, called the meninges. There are several types of meningitis. The most common is viral meningitis.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
