Multi-level tuberculosis of the spine identified by 18 F-FDG-PET/CT and concomitant urogenital tuberculosis: a case report from the spinal TB X cohort.

BACKGROUND: Tuberculosis (TB) is caused by Mycobacterium tuberculosis (Mtb) and typically infects the lungs. However, extrapulmonary forms of TB can be found in approximately 20% of cases. It is suggested, that up to 10% of extrapulmonary TB affects the musculoskeletal system, in which spinal elements (spinal tuberculosis, STB) are involved in approximately 50% of the cases. STB is a debilitating disease with nonspecific symptoms and diagnosis is often delayed for months to years. In our Spinal TB X Cohort, we aim to describe the clinical phenotype of STB using whole-body 18 F-fluorodeoxyglucose positron emission tomography computed tomography (PET/CT) and to identify a specific gene expression profile for the different stages of dissemination on PET/CT. Here we report on the first patient recruited into our cohort who underwent PET/CT before treatment initiation, at 6-months and at 12-months - time of TB treatment completion. CASE PRESENTATION: A 27-year-old immunocompetent male presented with severe thoracolumbar back pain for 9 months with severe antalgic gait and night sweats. Magnetic resonance imaging (MRI) of the whole spine revealed multilevel spinal disease (T5/6, T11/12, L3/4) in keeping with STB. After informed consent and recruitment into the Spinal TB X Cohort, the patient underwent PET/CT as per protocol, which revealed isolated multilevel STB (T4-7, T11/12, L3/4) with no concomitant lung or urogenital lesion. However, sputum and urine were Xpert MTB/RIF Ultra positive and Mtb was cultured from the urine sample. CT-guided biopsy of the T11/12 lesion confirmed drug-sensitive Mtb on Xpert MTB/RIF Ultra and the patient was started on TB treatment according to local guidelines for 12 months. The 6-month follow-up PET/CT revealed new and existing spinal lesions with increased FDG-uptake despite significant improvement of clinical features and laboratory markers. After 9 months of treatment, the patient developed an acute urethral stricture, most likely due to urogenital TB, and a suprapubic catheter was inserted. The 12-month PET/CT showed significantly decreased PET/CT values of all lesions, however, significant persistent spinal inflammation was present at the end of TB treatment. Clinically, the patient was considered cured by the TB control program and currently awaits urethroplasty. CONCLUSIONS: In our case, PET/CT emerged as a valuable imaging modality for the initial assessment, surpassing MRI by revealing more comprehensive extensive disease. Subsequent PET/CT scans at 6-month uncovered new lesions and increased inflammation in existing ones, while by the end of TB treatment, all lesions exhibited improvement. However, the interpretation of FDG avidity remains ambiguous, whether it correlates with active infection and viable Mtb. or fibro- and osteoblast activity indicative of the healing process. Additionally, the absence of extraspinal TB lesions on PET/CT despite positive microbiology from sputum and urine maybe explained by paucibacillary, subclinical infection of extraspinal organs. The Spinal TB X Cohort endeavours to shed light on whole-body imaging patterns at diagnosis, their evolution midway through TB treatment, and upon treatment completion. Ultimately, this study aims to advance our understanding of the biology of this complex disease.

Conservative management for pediatric craniocervical Pott's disease: A case study and literature review.

Craniocervical Pott's disease is rare, particularly in the pediatric population. The importance of motion preservation in this age group renders managing this disease even more challenging. The literature regarding craniocervical Pott's disease comes from endemic regions. Most authors will agree on early surgical intervention in cases of neurological compromise or severe instability, while patients with minimal symptoms will do well with conservative management. Controversy remains when patients are mildly symptomatic but with imaging findings concerning for significant instability. Here, we present the case of a 15-year-old male presenting with craniocervical tuberculoma with radiographic instability and advanced bony destruction without overt neurological deficits. He was managed with a rigid cervical collar and completed 1 year of anti-tuberculosis therapy. At 1-year follow-up, he had an intact range of motion, was pain-free, and remained neurologically intact. Although this case suggests good outcomes with conservative management are possible, more long-term follow-up is required to assess the need for delayed surgical intervention in this unique population.

Edward Hickling Bradford (1848-1926): The Founder of Pediatric Orthopedics in America.

Edward Hickling Bradford (1848-1926) is considered as 1 of the most important figures in American and world orthopedics during 19th and early 20th century. His teaching ability, his gifted surgical skills and his innovations in orthopedics attracted the interest of the world orthopedic's community and gave him a long lasting reputation. But most of all he is considered as the founder of pediatric orthopedics in America.

Percivall Pott (1713-1788) on the curvature of the spine and the French contribution.

Physicians remember the name of the surgeon Percivall Pott (1713-1788) because of the eponym "Pott's disease", described as "paralysis in the lower limbs, which is often accompanied by curvature of the spine". Pott's writings on surgical subjects are far vaster. For example, he described the fracture-dislocation of the ankle, or Pott's fracture, and determined the cause of scrotum cancer in chimney sweeps. He attributed this disease to contact with tar that contaminated the clothing of workers, often very young children because they were small enough to fit into chimney conduits. His work led to the first law addressing the employment of children. After a brief account of Pott's life, this article presents the description of Pott's paraplegia, for which both Jean-Martin Charcot and Yvonne Sorrel-Dejerine paid him homage. The contribution of some of his predecessors and of French contemporaries is highlighted. Pott was also a pioneer in neurosurgery, describing the non-symptomatic interval between cranial trauma and coma and the indication for trepanation to remove a haematoma.

Pott's disease associated with bilateral psoas abscess: a case report on surgical management using anterior approach.

Pott's disease may accompany psoas abscesses, but bilateral psoas abscess is rarely encountered. Computerised Tomography (CT) is the gold standard for the diagnosis of psoas abscesses. Treatment of psoas abscess usually involves drainage of abscess and antibiotic therapy. CT and USG-guided catheters are often utilised for abscess drainage. In cases where neurological symptoms are observed, open surgery may be required. Pott's disease accompanied by bilateral psoas abscess was detected in a 21-year-old male patient who was admitted to the clinic with complaints of low back pain and weakness in his left leg at the Selcuk University, Turkey, in 2018. The reason for the development of neurological deficit only on the left side was the compression of the nerve roots by the abscess tissue. The patient underwent debridement and anterior instrumentation with an anterior approach. In the postoperative follow-up it was observed that the patient's complaints were relieved. Pott's disease with bilateral psoas abscesses, in which debridement and instrumentation with an anterior approach is applied, has not been previously reported in the literature, and the current case is a first in this respect.

The potential of bone disease for personal identification: a case of tuberculosis.

In the forensic anthropology practice, bone diseases are rarely considered for personal identification. In this paper, we present a forensic skeletonized case with tuberculous bone lesions, for which bone pathology may provide an indicator for positive personal identification. Antemortem hospital records were available. Postmortem CT scans of the pathologically affected bones were performed, and 3D reconstructions with Global Illumination Reconstruction software (GIR) were realized, in order to confront antemortem and postmortem data. As a result, the juxtaposition and superimposition of antemortem and postmortem images evidenced several points of correspondence in the position, anatomical contour, character, and morphological characteristics of the bone lesions, thus demonstrating through a concrete case study the potential of morphological features of bone lesions for the personal identification of unknown deceased.

Paralytic ileus in the patient with tuberculosis of spine.

Background: We reported a patient with spinal tuberculosis and paralytic ileus. A 56-year-old Javanese male presented with lower limb paralysis and bowel obstruction 2 weeks prior to admission. He was found to have hypoalbuminemia and hypesthesia from the T7/T9 levels and below. Other than increased alanine aminotransferase, hematology and blood chemical tests were normal. MRI and plain abdominal radiographs confirmed the diagnosis of spinal tuberculosis at the T5/6 level and paralytic ileus. Tubercles in the lymphoid tissue of the intestinal submucosa were not seen.Conclusion: Paralytic ileus may occur in spinal TB.

Lesions Consistent with Tuberculous Spondylitis in Domestic and Wild Swine and Their Potential Use as a Model for Pott Disease in Humans.

During a routine abattoir inspection of pig carcasses and control activities of hunted wildlife in 2013, 118 large white pigs Sus scrofa domesticus, 474 Nebrodi black pigs and 135 wild boars Sus scrofa scrofa were submitted to anatomopathological examination to evaluate the presence of tuberculosis-like lesions. Localized and generalized granulomatous lesions were detected with a prevalence of about 25% in large white pigs, 13% in Nebrodi black pigs and 8.15% in wild boars. Localized lesions involved mainly the submandibular lymph nodes, but when the disease was spread throughout the body, the inner organs and, also, in some cases, udders and/or bones were injured. The highest prevalence of generalized lesions (15/30) was observed in large white pigs, the only ones in which tuberculous granuloma affected also the spine. The bovine tuberculous spondylitis cases observed showed some similarities with Pott disease in humans regarding aspect and localization of lesions and age of the affected animals.Tissue samples of the positive animals were collected and submitted to bacteriological analysis, and the bone samples were also subjected to histological and immunohistochemistry analysis. M. bovis was isolated in all the analysed samples, and the granuloma encapsulation was found often incomplete indicating that the disease was in an active phase. The presence of lesions associated to tuberculous spondylitis in pigs suggests the possibility to use this animal species as model for the study of Pott disease in humans.

Surgical approaches to upper thoracic Pott's disease with spinal instability during childhood: two cases.

PURPOSE: Tuberculosis is a common disease worldwide that is caused by Mycobacterium tuberculosis. Tuberculosis is primarily a pulmonary disease, but extrapulmonary manifestations are not uncommon, especially in children and adolescents. METHODS: We present two pediatric patients who underwent surgery in our clinic for Pott's disease in the upper thoracic region. The patients were investigated to describe their age, complaints, neurological examination results, disease location, surgical procedure, and complications. RESULTS: The patients were 2 and 14 years old and exhibited disease located in the upper thoracic region (T2-T3 and T1-T2). Both patients displayed severe neurological deficits (Frankel B and C). The kyphotic angles were 82.2° and 43.2°. The patients were stabilized by applying fusion using transpedicular screws via a posterior approach. They also underwent anti-tuberculosis treatment for approximately 1 year. One year later, neither patient exhibited any neurological deficit, and their kyphotic angles were measured as 11° and 1°, respectively. CONCLUSIONS: The recommended treatment approach for unstable cases of Pott's disease located in the upper thoracic region who exhibit neurological deficit and severe kyphotic angling or the development of kyphosis on the thoracic vertebrae is surgical. Decompression, stabilization, and fusion and kyphotic correction can be safely performed via a posterior approach. One of the present cases is the youngest patient described in the literature to undergo transpedicular surgery as a result of Pott's disease. Our other case is the first described in the literature who developed ptosis as a result of tuberculosis and underwent a procedure via posterior transpedicular screw.

Unusual circumstances to diagnose cervical Pott's disease.

Tuberculous spondylodiscitis usually affects the dorso-lumbar spine, and its cervical location is a rare condition that can mimic other diseases and consequently cause treatment delays. We report a case of tuberculous spondylodiscitis of the lower cervical spine discovered under unusual circumstances in a patient with severe polytrauma involving a cranio-cerebral trauma, a non-displaced fracture of the two laminæ and the spinous process of the C6 vertebrae as well as fibular and tibial shaft fractures. The patient underwent static tibial nailing, and a collar with occipital and chin supports was applied. At 2-month follow-up, the patient presented with severe neck pain without neurologic deficits. Plain and dynamic cervical radiographs showed a stable C6-C7 subluxation and C7 superior endplate collapse. The CT scan also outlined prevertebral soft tissue swelling. The MRI showed a C6-C7 spondylodiscitis associated with a prevertebral abscess with am 8-cm major axis. The diagnosis of C6-C7 Pott's disease was confirmed by a CT-guided biopsy. The patient received 12 months of antituberculous chemotherapy, after which the paravertebral abscess completely disappeared, and the patient has had no functional sequelae. The diagnosis of cervical spine tuberculosis is difficult and requires a high level of attention. Delays in establishing the diagnosis and starting the appropriate treatment result in severe complications such as spinal cord compression and spinal deformity, which are difficult to manage.

Pott's Disease in a Patient with Subtle Red Flags.

BACKGROUND: Tuberculosis (TB) is now rare in developed countries; however, it is an important diagnosis for the Emergency Physician to be able to make. Classically thought of as a respiratory disease, TB can present in other ways, making it more challenging to recognize. CASE REPORT: We report the case of a 41-year-old woman who presented to the Emergency Department with a 4-week history of back pain. A diagnosis of T12 osteomyelitis and right psoas muscle abscess was made after magnetic resonance imaging. The concurrent finding raised concern for TB as psoas muscle abscess is usually found along with spinal TB. A computed tomography-guided fine-needle aspiration confirmed the diagnosis. This patient's social history was negative for many of the classic predisposing factors associated with TB: immunosuppression, personal travel, crowded living conditions. Repeated investigation into the patient's history revealed a visit several months prior from a family member from Vietnam who had been treated for TB. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important for Emergency Physicians to be aware of the relatively high incidence of TB as a cause for concurrent psoas abscess and vertebral osteomyelitis.

[Osteoarticular tuberculosis nosology and diagnostic pitfalls]. / Tuberculose ostéoarticulaire : nosologie et pièges diagnostiques.

Osteoarticular or skeletal tuberculosis is a clinical manifestation of extrapulmonary tuberculosis, occurring during the lympho-hematogenous spread of Mycobacterium tuberculosis from a pulmonary primary infection or reactivation of latent infection, years or even decades after the initial infection. Bone and joint tuberculosis is a rare disease with non-specific symptoms and radiological characteristics, often delaying diagnosis for more than a year after clinical onset. First-line hospital departments should develop a clinical suspicion when confronted with a subacute inflammatory bone or joint pathology in patients with underlying comorbidities, especially when coming from tuberculosis-endemic countries. We report a clinical case characterized by lumbar and pelvic abscesses, before addressing in detail the different types of skeletal involvement related to tuberculosis, through a review of the literature.

La tuberculose ostéoarticulaire ou osseuse est une manifestation clinique de la tuberculose extra-pulmonaire, apparaissant lors de la dissémination lympho-hématogène de Mycobacterium tuberculosis à la suite d'une infection pulmonaire primaire ou la réactivation d'une infection latente, des années, voire des décennies après une primo-infection. Il s'agit d'une maladie rare dont les symptômes ainsi que les signes radiologiques sont non spécifiques, ce qui retarde souvent le diagnostic de plus d'un an après les premiers signes cliniques. Les services hospitaliers de première ligne doivent suspecter le diagnostic en cas de pathologie inflammatoire subaiguë des os ou des articulations chez des patients avec comorbidités, surtout s'ils sont originaires de régions endémiques pour la tuberculose. Nous rapporterons un cas clinique caractérisé par des abcès lombaires et pelviens avant d'aborder en détail les différents types d'atteintes squelettiques de la tuberculose au travers d'une revue de la littérature.

The changing epidemiology of spinal tuberculosis: the influence of international immigration in Catalonia, 1993-2014.

The overall incidence of spinal tuberculosis (TB) appears to be stable or declining in most European countries, but with an increasing proportion of cases in the foreign-born populations. We performed a retrospective observational study (1993-2014), including all cases of spinal TB diagnosed at a Barcelona hospital to assess the epidemiological changes. Fifty-four episodes (48·1% males, median age 52 years) of spinal TB were diagnosed. The percentage of foreign-born residents with spinal TB increased from 14% to 45·2% in the last 10 years (P = 0·017). Positive Mycobacterium tuberculosis testing in vertebral specimens was 88·2% (15/17) for GeneXpert MTB/RIF. Compared with natives, foreign-born patients were younger (P < 0·01) and required surgery more often (P = 0·003) because of higher percentages of paravertebral abscess (P = 0·038), cord compression (P = 0·05), and persistent neurological sequelae (P = 0·05). In our setting, one-third of spinal TB cases occurred in non-native residents. Compared with natives, foreign-born patients were younger and had greater severity of the disease. The GeneXpert MTB/RIF test may be of value for diagnosing spinal TB.

Tuberculous spondylitis diagnosed through Xpert MTB/RIF assay in urine: a case report.

BACKGROUND: Extrapulmonary tuberculosis (EPTB) is associated with high rates of morbidity and mortality. Diagnosis of EPTB is challenging in resource-limited settings due to difficulties in obtaining samples, as well as the paucibacillarity of the specimens. Skeletal tuberculosis accounts for 10-35 % of EPTB cases, with vertebral osteomyelitis (Pott's disease) representing 50 % of the cases. We present two cases of suspected Pott's disease, diagnosed through GeneXpert MTB/RIF assay in urine at a rural Tanzanian hospital. CASE PRESENTATION: Case I A 49-year old male, HIV-1 positive, on co-formulated tenofovir disoproxil fumarate/lamivudine/efavirenz since 2009 and CD4 counts of 205 cells/µL (13 %). He presented with lower back pain and progressive lower limb weakness for two weeks prior to admission. The physical examination revealed bilateral flaccid paraplegia with reduced reflexes, but otherwise unremarkable findings. A lateral lumbar X-ray showed noticeable reduction of intervertebral space between L4 and L5, and a small calcification in the anterior longitudinal ligament between L4 and L5, being compatible with focal spondylosis deformans but inconclusive with regard to tuberculous spondylitis. An abdominal ultrasound showed normal kidneys, bladder and prostate gland. The urinalysis and complete blood counts (CBC) were normal. M. Tuberculosis was detected through GeneXpert MTB/RIF in centrifuged urine, with no resistance to rifampicin. Case II A 76-year old female, HIV-1 negative, presented with lower back pain and progressive weakness and numbness of the lower limbs for two months prior to admission. The physical examination revealed paraplegia, but otherwise unremarkable findings. The lumbosacral X-ray findings were compatible with spondylosis deformans of the lumbar spine and possible tuberculous spondylitis in L3-L4. The abdominal and renal ultrasound showed normal kidneys and bladder. The urinalysis and CBC were normal. M. Tuberculosis was detected through GeneXpert MTB/RIF in centrifuged urine, with no resistance to rifampicin. CONCLUSION: We report two cases of suspected tuberculous spondylitis diagnosed through Xpert MTB/RIF in urine samples from a rural Tanzanian hospital. Urine testing using Xpert MTB/RIF reflects disseminated disease and renal involvement, and may offer a feasible additional diagnostic approach for Pott's disease in rural Africa.

Minimum 5-year follow-up outcomes for single-stage transpedicular debridement, posterior instrumentation and fusion in the management of thoracic and thoracolumbar spinal tuberculosis in adults.

AIM: The aim of this retrospective clinical study is to evaluate the long-term outcomes for single-stage transpedicular debridement, posterior instrumentation and fusion in the management of thoracic and thoracolumbar spinal tuberculosis in adults. METHODS: Fifty-nine adult patients with thoracic and thoracolumbar spinal tuberculosis underwent single-stage transpedicular debridement, posterior instrumentation and fusion. These patients were followed for a minimum of 5 years. Patients were assigned to one of two groups according to the infected anatomic segment. In the thoracic spinal tuberculosis group, there were 28 cases (17 males, 11 females) with a mean age of 38.9 years; in the thoracolumbar spinal tuberculosis group, there were 31 cases (19 males, 12 females) with a mean age of 40.3 years. All cases were evaluated clinically using the visual analog scale (VAS), Kirkaldy-Willis criteria and the American Spinal Injury Association (ASIA) impairment scale. Radiographs were performed for measuring the angle of kyphosis and scoliosis. Complications related to surgery were recorded. RESULTS: All patients successfully resolved their infections, experienced one or more ASIA grades of improvement, and improved in their VAS pain scores at final follow-up. In both groups, patient-reported outcomes reached over 90% excellent or good results using Kirkaldy-Willis criteria. The loss of kyphotic angle correction was 2.6° in the thoracic spinal tuberculosis group and 3.2° in the thoracolumbar spinal tuberculosis group. No scoliosis was observed in either group. Fifty-eight (98.3%) cases achieved solid bony fusion. In the thoracolumbar spinal tuberculosis group, one patient experienced screw loosening, and another patient with nonunion and rod breakage underwent revision surgery. CONCLUSIONS: The technique of single-stage transpedicular debridement, posterior instrumentation and fusion is an effective method for the treatment of thoracic and thoracolumbar spinal tuberculosis in adults. Long-term postoperative clinical and radiological outcomes were satisfactory.

Characteristics and Clinical Outcome of Bone and Joint Tuberculosis From 1994 to 2011: A Retrospective Register-based Study in Denmark.

BACKGROUND: Most information on bone-joint (BJ)-tuberculosis is based on data from high-incidence areas. We conducted a nationwide register-based analysis of BJ-tuberculosis in Denmark from 1994 to 2011. METHODS: We linked data from the national tuberculosis surveillance system on BJ-tuberculosis, hospital records, the Danish Hospital and Civil Registration System. RESULTS: We identified 282 patients with BJ-tuberculosis, 3.6% of all tuberculosis cases (n = 7936). Spinal tuberculosis was found in 153 of 282 patients (54.3%); 83.3% of all cases were immigrants. Danes were older and had higher Charlson comorbidity index scores than immigrants (P < .01). C-reactive protein and erythrocyte sedimentation rates were elevated in most cases. Median time to diagnosis after first hospital contact was 19.5 days for spinal tuberculosis and 28 days for other forms of BJ-tuberculosis (P = .01). Of patients with spinal tuberculosis, 54/133 (40.6%) had neurologic deficits at admission and 17.3% presented with cauda equina. Diagnosis was culture verified in 87%. (Resistance to any drug was found in 10.2%). Median time on antituberculous treatment for patients with spinal and other forms of BJ-tuberculosis was 9 months and 7 months, respectively (P < .01). Surgery was required in 44.4% patients with spinal tuberculosis and in 32.6% patients with other forms of BJ-tuberculosis (P = .04). Sequelae were reported in 57.5% of patients with spinal tuberculosis and 29.1% of patient with other forms of BJ-tuberculosis (P < .01). One-year mortality was 25.5% among Danes compared with 1.3% among immigrants (P < .01). CONCLUSIONS: BJ-tuberculosis was rare and seen mainly in younger immigrants in Denmark. More than half of cases were spinal tuberculosis, presenting with more severe symptoms and worse outcome, compared with other forms of BJ-tuberculosis.

Skeletal evidence of tuberculosis in a modern identified human skeletal collection (Certosa cemetery, Bologna, Italy).

The diagnosis of tuberculosis (TB) in osteoarcheological series relies on the identification of osseous lesions caused by the disease. The study of identified skeletal collections provides the opportunity to investigate the distribution of skeletal lesions in relation to this disease. The aim of this study was to examine the skeletal evidence for TB in late adolescent and adult individuals from the identified human collection of the Certosa cemetery of Bologna (Italy, 19th-20th c.). The sample group consists of 244 individuals (138 males, 106 females) ranging from 17 to 88 years of age. The sample was divided into three groups on the basis of the recorded cause of death: TB (N = 64), pulmonary non-TB (N = 29), and other diseases (N = 151). Skeletal lesions reported to be related to TB were analyzed. The vertebral lesions were classified into three types: enlarged foramina (EnF, vascular foramina with diameter of 3-5 mm), erosions (ER), and other foramina (OtF, cavities of various shapes > 3 mm). A CT scan analysis was also performed on vertebral bodies. Some lesions were seldom present in our sample (e.g., tuberculous arthritis). OtF (23.7%) and subperiosteal new bone formation on ribs (54.2%) are significantly more frequent in the TB group with respect to the other groups. The CT scan analysis showed that the vertebrae of individuals who have died of TB may have internal cavities in the absence of external lesions. These traits represent useful elements in the paleopathological diagnosis of TB.

Mistaken identity: Reporting two cases of rare forms of extrapulmonary tuberculosis in Solomon Islands.

INTRODUCTION AND IMPORTANCE: Extrapulmonary tuberculosis (EPTB) is a relatively rare and difficult-to-diagnose manifestation of Myobacterium tuberculosis (TB) infection. CASE PRESENTATION: This study reports the cases of a 47-year-old male and a 35-year old female with rare forms of EPTB who sought medical care in Solomon Islands. Both patients presented with nondescript symptoms and a chief complaint of pain. Initial diagnosis for the male and female patient was an abacterial colon polypoid mass and a urinary tract infection (UTI) respectively. Following unsuccessful treatment for UTI and further investigation, the surgical team diagnosed the female patient with a tuberculosis spondylitis and a bilateral psoas abscess. The male patient was subsequently diagnosed with isolated colonic tuberculosis. After starting medication, the patients were discharged and prescribed 9-month treatment regimens. During outpatient treatment both patients reported suboptimal adherence. The female patient resumed treatment and showed improvement while the male patient discontinued treatment, experienced worsening symptoms, and ultimately died. CLINICAL DISCUSSION: The nonspecific symptoms of extrapulmonary TB infection make it difficult to diagnose. Cases of rare forms of EPTB are particularly challenging to identify. Misdiagnosis may further increase the likelihood of mortality and morbidity in these cases. Intensive medication counseling, patient outreach, and regularly scheduled follow-up visits may reduce the incidence of poor adherence and reduce the risk of developing drug-resistant TB. CONCLUSION: Medical practitioners in tuberculosis-endemic countries like Solomon Islands should maintain a high clinical index of suspicion in diagnosing EPTB. Future research should investigate the prevalence of TB and EPTB in the Solomon Islands.

Pediatric and adult meningeal, parenchymal, and spinal tuberculosis: A neuroimaging review.

Neurotuberculosis is defined as a tuberculous infection of the meninges, brain parenchyma, vessels, cranial and spinal nerves, spinal cord, skull, and spine that can occur either in a localized or in a diffuse form. It is a heterogeneous disease characterized by many imaging appearances and it has been defined as "the great mimicker" due to similarities with many other conditions. The diagnosis of central nervous system (CNS) tuberculosis (TB) is based on clinical presentation, neuroimaging findings, laboratory and microbiological findings, and comprehensive evaluation of the response to anti-TB drug treatment. However, the absence of specific symptoms, the wide spectrum of neurological manifestations, the myriad of imaging findings, possible inconclusive laboratory results, and the paradoxical reaction to treatment make the diagnosis often challenging and difficult, potentially delaying adequate treatment with possible devastating short-term and long-term neurologic sequelae. Familiarity with the imaging characteristics helps in accurate diagnosis and may prevent or limit significantly morbidity and mortality. The goal of this review is to provide a comprehensive up-to-date overview of the conventional and advanced imaging features of CNS TB for radiologists, neuroradiologists, and pediatric radiologists. We discuss the most typical neurotuberculosis imaging findings and their differential diagnosis in children and adults with the goal to provide a global overview of this entity.
