Tuberculous meningitis is a severe manifestation of extrapulmonary tuberculosis, often associated with
substantial morbidity and mortality. This case report discusses a unique presentation of tuberculous
meningitis in a 39-year-old male who was concurrently positive for COVID-19. The patient initially
presented with symptoms of COVID-19, including fatigue, fever, and respiratory distress. However,
subsequent neurological symptoms, including facial asymmetry, ptosis, and dysphagia, led to further
evaluation. Imaging and cerebrospinal fluid analysis confirmed the diagnosis of tuberculous meningitis.
Treatment involved a multidrug regimen and supportive care in an intensive care unit. The patient was
eventually discharged with residual neurological deficits. This case emphasizes the importance of
considering tuberculous meningitis in the context of COVID-19, particularly in regions with a high
burden of tuberculosis. Timely diagnosis, through clinical evaluation and diagnostic tools such as
cerebrospinal fluid analysis and radiographic imaging, is crucial for effective management. The
potential risk of TB reactivation in COVID-19 patients underscores the need for continued vigilance and
prompt intervention to prevent severe disease outcomes.
Key words: Covid-19, tuberculous meningitis, reactivation
INTRODUCTION
Tuberculosis (TB) is a significant global health concern
and remains one of the leading causes of death worldwide
(World Health Organization, 2022a). It is an infectious
disease caused by the Mycobacterium tuberculosis. TB is
spread through the air when an infected person coughs
or sneezes. It primarily affects the lungs, but can also
affect other parts of the body (Centers for Disease
Control and Prevention, 2022).
TB can present in two main forms: latent TB infection and
active TB disease. Latent TB infection occurs when a
person has been infected with the TB bacteria but does
not yet have active disease or symptoms. In this case,
the bacteria are dormant and cannot be spread to others.
However, people with latent TB infection are at risk of
developing active TB disease if their immune system
becomes weakened (Centers for Disease Control and

Prevention, 2022). COVID-19 infection can increase the
risk of TB reactivation due to a combination of factors.
These factors include immune system suppression, as
well as disruptions to TB diagnosis, treatment, and
prevention services (World Health Organization, 2022b).
Tuberculous meningitis (TBM) is one of the most
severe manifestations of extrapulmonary TB. CNS-TB
represented the 13.91% of all cases of meningitis and
4.55% of all cases of TB (Navarro-Flores et al., 2022).
The pathophysiology is primarily driven by three
components, which also explain the clinical symptoms
(Rich and McCordock, 1933; Dastur et al., 1995). Thick
gelatinous exudate, which is especially apparent at the
basal region of the brain, eventually produces a fibrous
mass that encases nearby structures. As a result,
periventricular infarcts and cranial nerve palsies are
developed. Spasm, constriction, thrombosis, and
occlusion of intracerebral arteries are all possible effects
of tuberculous vasculitis and the concomitant
inflammatory vascular changes (Chan et al., 2005). The
intracranial vasculitis is expected to have a major impact
on the remaining neurologic deficits (Poltera, 1977).
Clinical approach and diagnostic tools, including CSF
analysis and radiographic imaging, are equally important
to diagnose TB meningitis (Lewinsohn et al., 2017). The
treatment for tuberculous meningitis is very complex.
Commonly, the combination of Isoniazid, Rifampin,
Pyrazinamide and Ethambutol/Streptomycin/
Fluoroquinolone is given for an extended period of time.
However, sometimes drug resistance is found which
leads to adjustments in treatment (Donald, 2010; World
Health Organization, 2017). This case describes the
development of tuberculous meningitis in a patient with
COVID-19.
CASE PRESENTATION
39-year-old male presented to the emergency department
on June 4, 2022, with fatigue, fever, shortness of breath,
nausea, and vomiting. He tested positive for COVID-19.
A cardiopulmonary examination showed clear lung fields
and normal heart sounds. Neurological assessment
showed signs of ataxia, vertigo, and horizontal
nystagmus; however, a head CT scan has not shown any
pathological features. Two days later, the patient
developed new clinical signs, including facial asymmetry
with loss of the left nasolabial fold, right-sided ptosis,
spontaneous rotatory nystagmus, dysphagia, dysarthria,
and trouble coordinating. Jaw jerk and gag reflexes were
both diminished. Reduced deep tendon reflexes were
present in all extremities, more so on the left. He also
suffered from neck rigidity.
A head MRI revealed hyperintensity in the brainstem
and left cerebellum (Figures 1 and 2). CSF analysis
revealed lymphocytosis, decreased glucose, and
elevated protein. Adenosine deaminase levels and CSF
PCR for tuberculosis were both positive as well.
Following the lumber puncture, treatment with
Dexamethasone, Vancomycin, and Ceftriaxone was
started immediately due to an increased suspicion of
meningitis. After the patient's cerebrospinal fluid results
confirmed TB meningitis, the treatment regimen was
adjusted to Streptomycin, Rifampicin, Isoniazid,
Pyrazinamide and Dexamethasone.
The following day, the patient was diagnosed with
purulent endobronchitis based on an X-ray and
bronchoalveolar lavage. Soon after, he developed a
cytokine storm and was taken to the intensive care unit,
where he was intubated, sedated, and mechanically
ventilated. Due to a protracted need for breathing
support, he underwent tracheostomy placement. The
patient was taken off the ventilator on July 9th, 2022, but
continued to receive oxygen through a tracheostomy.
On August 1, 2022, the patient was discharged with
stable vital signs. Oropharyngeal and cardiopulmonary
examinations revealed no abnormalities. During
neurological examination, the patient was spatially and
temporally oriented and was able to follow simple
commands. Pupils were equally round and light-
responsive. However, he still displayed dysmetria and
Babinski reflex on the left side, along with horizontal
nystagmus, as residual neurological deficit. The patient
was advised to take Rifampicin and Isoniazid for 9
months.
Ethics section
Informed consent was obtained from the patient prior to
data collection, ensuring their comprehensive
understanding of the study's objectives, potential
implications, and the confidentiality of their sensitive
medical information. The patient was provided with
detailed information about the case report, including its
purpose, methodology, and the intended use of medical
records and clinical details. It was explicitly communicated
that participation in the study was entirely voluntary, and
the patient could opt out at any stage without affecting
their medical care or rights. Emphasis was placed on the
de-identification of all data, ensuring the anonymity of the
patient. The patient was reassured that the patient's
personal and medical information would be treated with
the utmost confidentiality and solely utilized for the
purpose of this case report.
DISCUSSION
Based on this case, it is apparent that even a benign
case of COVID-19 may eventually lead to severe
consequences, such as TB reactivation. The timely
identification of early neurological manifestations allowed
for prompt evaluation and diagnosis of TB meningitis,

which prevented further delays in treatment. So, despite
the severity and complexity of the presented case, the
overall outcome was positive. However, it should be
mentioned that the patient still developed a residual
neurological deficit.
Conclusion
In conclusion, this case highlights that the potential
complications and challenges associated with COVID-19
infection extend beyond the impact of a single infectious
Megrelishvili et al. 3
agent. The combined effects of multiple factors can
significantly affect various organ systems, including the
nervous system. COVID-19 affects several organ
systems, thus any symptom could be attributed to it and
underlying pathology may go unnoticed. The immune
system suppression induced by COVID-19 can increase
the risk of TB reactivation, thereby complicating diagnosis
and treatment. Therefore, it is crucial to consider the
possibility of TB reactivation in COVID-19 patients,
particularly those from regions with high TB prevalence.
Therefore, timely detection and prompt treatment of TB
are essential to prevent severe complications and
improve clinical outcomes in these patients.

Background Tuberculosis (TB) is the second most common cause of death due to a single infectious agent worldwide after COVID-19. Up to 15% of the cases are extrapulmonary, and if it is located in the central nervous system (CNS-TB), it presents high morbidity and mortality. Still, the global epidemiology of CNS-TB remains unknown. Aim To estimate the global prevalence and incidence of CNS-TB based on the available literature. Methods We systematically searched in MEDLINE, Cochrane Central, Scopus, and LILACS databases (April 2020) and included observational studies evaluating the epidemiology of CNS-TB. Two independent researchers selected and assessed the quality of the studies and extracted relevant data. We performed random-effects model meta-analysis of proportions to estimate the pooled prevalence. The protocol of this study was registered in PROSPERO (CRD 42018103946). Results We included 53 studies from 28 countries, representing 12,621 patients with CNS-TB. The prevalence of CNS-TB was 2 per 100,000 inhabitants. According to the clinical setting, the prevalence of CNS-TB represented the 13.91% of all cases of meningitis and 4.55% of all cases of TB. The mortality was calculated by tuberculous meningitis due to the lack of data of other presentation, and it rose up to 42.12% in hospitalized patients. The burden of countries’ TB, Human Development Index (HDI), and the prevalence of HIV were the most important prevalence moderators, especially in patients with TB. No data on incidence were found. Conclusion The prevalence and mortality of CNS-TB remain high, and TB meningitis is the most frequent presentation. The highest prevalence was reported in developing countries, and its main moderators were the countries’ HDI and HIV infection. Our study was limited by high heterogeneity, risk of bias, and potential data under registration from developing countries. The integration of CNS-TB early detection and management into national TB programs and population-based studies from developing countries are needed for better global estimation and response.
Article
Background: Individuals infected with Mycobacterium tuberculosis (Mtb) may develop symptoms and signs of disease (tuberculosis disease) or may have no clinical evidence of disease (latent tuberculosis infection [LTBI]). Tuberculosis disease is a leading cause of infectious disease morbidity and mortality worldwide, yet many questions related to its diagnosis remain. Methods: A task force supported by the American Thoracic Society, Centers for Disease Control and Prevention, and Infectious Diseases Society of America searched, selected, and synthesized relevant evidence. The evidence was then used as the basis for recommendations about the diagnosis of tuberculosis disease and LTBI in adults and children. The recommendations were formulated, written, and graded using the Grading, Recommendations, Assessment, Development and Evaluation (GRADE) approach. Results: Twenty-three evidence-based recommendations about diagnostic testing for latent tuberculosis infection, pulmonary tuberculosis, and extrapulmonary tuberculosis are provided. Six of the recommendations are strong, whereas the remaining 17 are conditional. Conclusions: These guidelines are not intended to impose a standard of care. They provide the basis for rational decisions in the diagnosis of tuberculosis in the context of the existing evidence. No guidelines can take into account all of the often compelling unique individual clinical circumstances.
Article
Tuberculous meningitis (TBM) causes a devastating morbidity and mortality in adults and children. Even in patients presenting at an early stage of disease, deterioration may occur despite apparently adequate therapy. The literature relating to cerebrospinal fluid penetration of antituberculosis agents is reviewed. Amongst the essential antituberculosis agents isoniazid has the best CSF pharmacokinetics reaching peak concentrations (C(max)) only slightly less than in blood. Pyrazinamide also has good CSF penetration and in children receiving dosages of 40 mg/kg the CSF C(max) exceeds the proposed minimal inhibitory concentration of 20 μg/ml. Streptomycin other aminoglycosides and ethambutol have poor CSF penetration and cannot be agents of first choice for TBM treatment. Rifampicin at dosages used in adults seldom reaches CSF concentrations exceeding MIC, but does so more frequently in children when dosages of up to 20 mg/kg are used. The non-essential agents ethionamide, the fluoroquinolones, with the exception of ciprofloxacin, and cycloserine (terizadone) have relatively good CSF penetration and are recommended for TBM treatment. The dosages of the essential agents recommended for the treatment of TBM in children are INH 10 mg/kg (range 6-15 mg/kg bodyweight), rifampicin 15 mg/kg (range 10-20 mg/kg), pyrazinamide 35 mg/kg (range 30-40 mg/kg), ethambutol 20 mg/kg (range 15-25 mg/kg) and streptomycin 15 mg/kg (range 12-18 mg/kg). Amongst second-line agents ofloxacin, levofloxacin and moxifloxacin should be used in dosages of 15-20 mg/kg, ethionamide 20 mg/kg in a single dose, if tolerated, and for cycloserine (terizadone) 15 mg/kg. Antituberculous chemotherapy should be started as soon as the diagnosis of TBM is considered.
Article
The pathological features of twenty-three cases of tuberculous meningitis, examined over a twenty year period are reported. Ten cases, diagnosed clinically, were treated; thirteen undiagnosed cases were not treated. Phlebitis was found in twenty-two and arteritis of varying degrees in twenty. Tuberculous thrombophebitis was observed in eight cases and haemorrhagic infarction was present in ten. One case showed thrombosis in the territory of the mid-cerebral artery with ipsilateral white infarction; four presented white infarctions which were attributed to end- or panarteritic changes. previous descriptions of intracranial tuberculous thrombosis are briefly reviewed. Possible consequences of this vasculitis are mentioned.
Article
The mechanisms and the changes described herein typically begin with a dense basal meningeal exudate often resulting from a "Rich focus" along the basal surface of the cerebrum or ventricular ependyma. In the interpeduncular fossa, when the exudate is copious, among other structures the proximal parts of the optic nerves and of the internal carotid arteries are seen surrounded and compressed by the exudate. This exudate is made up of small and large mononuclear cells, including epithelioid cells, which also act as macrophages and may fuse to form Langhans' giant cells. Further extension of this exudate along small proliferating blood vessels into the brain substance constitutes a border zone encephalitis with the development of focal and diffuse ischemic brain changes due to vasculitis. Entrapment and occasional arteritic occlusion of larger arteries, such as the middle cerebral in the Sylvian fissures, results in infarction. Blockage of the basal subarachnoid cisterns around the midbrain and pons by the dense basal exudate or narrowing of aqueduct and third ventricle by a small tuberculoma causes consequent hydrocephalus. Development of many or one large focal granuloma (i.e., tuberculoma) occurs in the cerebrum, cerebellum, and/or brain stem. Similar pathogenetic mechanisms produce tuberculous spinal meningitis myeloradiculopathy that may be secondary to or occur before cranial tuberculous meningitis. More extensive damage to the white matter may occur together with the infrequent onset of perivascular demyelination on the basis of a hypersensitivity reaction to tuberculoprotein (i.e., "allergic tuberculous encephalopathy"). Finally, there may be a part played by NO in the production of the vascular and perivascular inflammatory central nervous system changes and a role for the the potential beneficial action of corticosteroids, especially in cases of tuberculous encephalopathy.
Article
Cerebral infarction (CI) is a serious complication of tuberculous meningitis (TBM). It can be asymptomatic or symptomatic, causing stroke. We studied 40 TBM patients. All had initial CT brain scan, CT/MRI brain scan 3 months later and urgent CT brain scan for deterioration. CI was classified into lacunar infarction (LI) or large artery infarction (LAI). Twelve (30%) had CI, in 9 (23%) it was symptomatic and in 3 (8%) silent. Seven (58%) had LAI +/- LI. Eight (67%) had multiple CI. Two died from brainstem CI and 6 were dependent at 1 year. Patients with LAI might develop posterior circulation CI more frequently than those with LI only. CI is a common complication of TBM locally, with LAI and multiple CI being common. Two thirds of TBM patients complicated by CI had poor prognosis despite adjunctive dexamethasone treatment.
