A17.89
Other tuberculosis of nervous system
Clinical Classification Guidelines
Inclusion Terms
- Tuberculous polyneuropathy
Medical Intelligence & Overview
ICD-10 Code A17.89 refers to a specific form of tuberculosis that affects the nervous system, known as other tuberculosis of the nervous system. This condition is a rare manifestation of tuberculosis where the bacteria infect parts of the nervous system, leading to various neurological symptoms. One common form of this condition is tuberculous polyneuropathy, which involves multiple nerves. Recognizing this condition is important, as it requires specialized diagnosis and treatment to manage the infection and its neurological effects.
Causes & Symptoms
Clinical Causes: Mycobacterium tuberculosis infection spreading to the nervous system Hematogenous dissemination of tuberculosis bacteria from the lungs or other sites Reactivation of latent tuberculosis in the nervous tissue Spread through adjacent structures or via the bloodstream to neural tissues
Key Symptoms: Weakness or paralysis in affected areas Numbness, tingling, or a burning sensation in the limbs Pain or discomfort along nerve pathways Difficulty coordinating movements Headache or neck stiffness in some cases Fever and general signs of infection in active cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation, imaging studies such as MRI or CT scans to detect nerve involvement, and laboratory tests including cerebrospinal fluid analysis. Culture of the cerebrospinal fluid or tissue samples can identify Mycobacterium tuberculosis. Sometimes, nerve conduction studies are used to assess peripheral nerve damage.
Treatment Protocols: Treatment focuses on a prolonged course of anti-tuberculosis medications, including rifampicin, isoniazid, ethambutol, and pyrazinamide. Adjunct therapies may include corticosteroids to reduce inflammation, supportive care for neurological symptoms, and physical therapy to maintain function. Early diagnosis and consistent treatment are crucial to prevent irreversible nerve damage.
