Summary
This case highlights a rare presentation of central nervous system tuberculosis (CNS TB) involving cerebral parenchymal involvement. Early diagnosis and treatment of CNS TB with Anti-Tubercular Therapy (ATT) and Multi-Drug Therapy (MDT) are crucial.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Leprosy patients with defaulted treatment are at risk for opportunistic infections.
- Central nervous system (CNS) involvement in tuberculosis is uncommon, with parenchymal involvement being extremely rare.
Purpose of the Study:
- To report an extremely rare case of CNS tuberculosis presenting as cortical encephalitis/cerebritis.
- To emphasize the importance of considering CNS TB in patients with neurological deficits and a history of leprosy.
Main Methods:
- Case report of a 53-year-old male with a history of leprosy.
- Diagnostic workup included cerebrospinal fluid (CSF) analysis, Magnetic Resonance Imaging (MRI), and lymph node biopsy.
- Treatment involved Anti-Tubercular Therapy (ATT), Multi-Drug Therapy (MDT) for leprosy, steroids, and anti-seizure medications (ASM).
Main Results:
- The patient presented with fever, cognitive impairment, and focal seizures with hemiparesis.
- MRI revealed cerebral cortical lesions and a paraspinal abscess.
- Mycobacterium Tuberculosis was detected via CBNAAT from the paraspinal fluid, and lymph node biopsy showed caseous necrosis.
- The patient showed significant clinical and radiological improvement with treatment.
Conclusions:
- Cortical encephalitis/cerebritis is an exceedingly rare manifestation of CNS tuberculosis.
- Prompt diagnosis and combined treatment for CNS TB and leprosy are vital for patient outcomes.
- Despite initial improvement, the patient succumbed to sepsis complications from secondary pneumonia.

Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
