Meningeal tuberculoma

This code signifies a localized, tumor-like mass of tuberculous granulation tissue specifically affecting the meninges, the membranes surrounding the brain and spinal cord. It represents a rare form of extrapulmonary tuberculosis, often presenting with symptoms related to increased intracranial pressure or focal neurological deficits.

Use this code when documentation clearly states a diagnosis of "meningeal tuberculoma" or "tuberculoma of the meninges." This diagnosis is typically confirmed through imaging studies (MRI, CT) showing a meningeal lesion, often with histological confirmation from biopsy or strong clinical suspicion in a patient with a history of tuberculosis exposure.

• Differentiate carefully from tuberculoma of the brain parenchyma or spinal cord, which are classified elsewhere.
• Always sequence this code after the underlying active tuberculosis if present and documented.
• Ensure documentation specifies "meningeal" to avoid confusion with other central nervous system tuberculomas.
