ICD-10: B90.0

ICD-10 code B90.0 refers to the sequelae of central nervous system tuberculosis. This code is part of the broader category of sequelae associated with infectious and parasitic diseases, specifically focusing on the long-term effects that can arise following an infection with tuberculosis (TB) that has affected the central nervous system (CNS).

Clinical Description

Overview of Central Nervous System Tuberculosis

Central nervous system tuberculosis is a severe form of extrapulmonary tuberculosis, which can manifest as tuberculous meningitis or tuberculomas. It occurs when Mycobacterium tuberculosis spreads to the CNS, leading to inflammation and potential damage to brain tissues. This condition is particularly serious and can result in significant morbidity and mortality if not diagnosed and treated promptly.

Symptoms and Clinical Manifestations

The clinical presentation of CNS tuberculosis can vary but often includes:

• Headaches: Persistent and severe headaches are common.
• Neurological Deficits: Patients may experience weakness, sensory loss, or seizures due to brain involvement.
• Altered Mental Status: Confusion, lethargy, or coma can occur, especially in advanced cases.
• Fever and Night Sweats: These systemic symptoms may accompany neurological signs.
• Nausea and Vomiting: Increased intracranial pressure can lead to these symptoms.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation, imaging studies (such as MRI or CT scans), and laboratory tests, including:

• Lumbar Puncture: Analysis of cerebrospinal fluid (CSF) can reveal elevated white blood cell counts, low glucose levels, and the presence of Mycobacterium tuberculosis.
• Imaging: MRI or CT scans may show meningeal enhancement, tuberculomas, or other signs of CNS involvement.

Treatment

The treatment of CNS tuberculosis involves a prolonged course of antitubercular medications, usually including:

• Rifampicin
• Isoniazid
• Pyrazinamide
• Ethambutol

Corticosteroids may also be administered to reduce inflammation and prevent complications.

Sequelae of CNS Tuberculosis

Following successful treatment of CNS tuberculosis, patients may experience various sequelae, which are the long-term effects resulting from the initial infection. These can include:

• Cognitive Impairment: Memory issues, difficulty concentrating, and other cognitive deficits may persist.
• Motor Deficits: Weakness or paralysis in certain muscle groups can occur, depending on the areas of the brain affected.
