ABSTRACT
La tuberculose est une des maladies infectieuses les plus répandues dans le monde .Elle représente un problème de santé publique majeur dans les pays en voie de développe ment, y compris l'Algérie . À l'échelle mondiale et parmi tous les cas de tuberculose, l'OMS rapporte 14 % de tuberculose extra-pulmonaire (TEP) sans atteinte pulmonaire concomitante. Dans notre pays et durant ces dernières années, une recrudescence de la tuberculose extrapulmonaire a été observée. L'objectif de cet article était de présenter un cas atypique de tuberculose cérébrale dont le diagnostic a été tardif, posé par l'examen anatomopathologique avec une revue de la littérature. C'est le cas d'une jeune patiente hospitalisée dans le cadre de l'urgence pour un syn drome d'hypertension intracrânienne avec troubles neurologiques. La tomodensitomé trie cérébrale a objectivé de multiples localisations cérébrales avec une hydrocéphalie active. Le bilan d'extension était sans anomalie. La patiente avait bénéficié d'une inter vention chirurgicale, les suites opératoires ont été favorables. L'examen anatomo-pa thologique était en faveur d'une lésion inflammatoire spécifique granulomateuse faite de larges plages de nécrose caséeuse. La patiente a répondu au traitement antituber culeux. Le problème diagnosticque et les résultats seront discutés avec une revue de la littéra ture. La tuberculose cérébrale est une forme rare de la tuberculose extra-pulmonaire. Le tableau clinique ainsi que la neuro-imagerie (TDM, IRM) sont atypiques. Le diagnostic était postopératoire, reposant sur l'examen anatomopathologique. Le pronostic dépend de la précocité du diagnostic, du siège de la lésion et de la réponse au traitement antituberculeux.
Tuberculosis is one of the most widespread infectious diseases in the world. It constitutes a major public health problem, especially in developing countries, including Algeria. Globally and among all tuberculosis cases, WHO reports 14% extra-pulmonary tuberculosis (EPT) without concomitant pulmonary involvement. In our country and in recent years, an upsurge in extrapulmonary tuberculosis has been observed. The objective of this article was to present an atypical case of cerebral tuberculosis whose diagnosis was late, made by anatomopathological examination with a review of the literature. We report the case of a young patient hospitalized in emergency for an intracranial hypertension syndrome with neurological disorders. Cerebral computed tomography revealed multiple brain locations with active hydrocephalus. The extension assessment was without anomaly. The patient underwent a surgical intervention, the operative consequences were favorable. The pathological examination was in favor of a specific inflammatory granulomatous lesion made up of large areas of caseous necrosis. The patient was cured under anti-tuberculosis treatment. The diagnostic problem and the results will be discussed with a review of the literature. Cerebral tuberculosis is a rare form of extrapulmonary tuberculosis. The clinic as well as the neuroimaging (CT, MRI) are atypical. The diagnosis is postoperative, based on the pathological examination. The prognosis depends on the early diagnosis, the site of the lesion and the response to anti-tuberculosis treatment.

Tuberculosis (TB) of the central nervous system (CNS) is considered one of the most severe forms of presentation of the disease. Although only 1% of TB cases involve the CNS, these cases represent around between 5 and 15% of extrapulmonary forms.1,2 Tuberculous meningitis (TBM) is the most frequent form of CNS TB. The granulomas formed in the cerebral tuberculoma may cause hydrocephalus and other symptoms indicative of a CNS mass lesion. In the absence of active TB or TBM, the symptoms may be interpreted as indicative of tumors.3,4 The prognosis is directly related to the early diagnosis and proper treatment installation.5 We report the case of a patient with intracranial hypertension syndrome, expansive mass in the parieto-occipital region, accompanied by a lesion in the rib, initially thought to be a metastatic lesion, although posteriorly diagnosed as a cerebral tuberculoma.

La tuberculosis causada por la bacteria Mycobacterium tuberculosis, se encuentra entre las 10 primeras causas de mortalidad a nivel mundial; la presentación extrapulmonar se produce por siembra vía hematógena o linfática desde un foco primario, correspondiendo a la afectación de sistema nervioso central el 5% de infecciones por TB y se presenta con menor frecuencia en personas inmunocompetentes. Las formas de tuberculosis de SNC son meningitis, tuberculosis espinal y tuberculomas que corresponden al 1% de infecciones por TB. El tratamiento se basa en la terapia antifímica, reservando el manejo neuroquirúrgico para puntuales indicaciones como deterioro neurológico, hidrocefalia o mala respuesta al tratamiento farmacológico.
Tuberculosis, caused by the Mycobacterium tuberculosis bacteria, is among the top 10 cau-ses of mortality worldwide; The extrapulmonary presentation is produced by hematogenous or lymphatic seeding from a primary focus, 5% of TB infections corresponding to central nervous system involvement and occurs less frequently in immunocompetent people. The forms of CNS tuberculosis are meningitis, spinal tuberculosis and tuberculomas that corres- pond to 1% of TB infections. The treatment is based on antifungal therapy, reserving neurosurgical management for specific indications such as neurodeterioration, hydrocephalus or poor response to pharmacological treatment

This paper describes six cases of tuberculosis in the central nervous system (CNS) of cattle in the state of Paraíba in northeastern Brazil. We reviewed the autopsy reports of 851 bovine necropsies performed from 2003 to 2016. Seventy-three (8.6%) cattle were diagnosed with tuberculosis and six showed lesions in the CNS. Three cases affected cattle up to two-year-old and other three affected adults. Three cattle presented exclusively nervous signs, two had respiratory signs and weight loss and one did not present any clinical signs. At necropsy, five cattle had thickening of the leptomeninges of the cerebellum, pons, obex, spinal cord and cortex, mainly, in the region near the brain basilar Willis´ circle. Another animal, presented a single focal lesion in the cerebellum. Microscopically we observed moderate to severe granulomatous meningitis and encephalitis. Five cattle presented lesions in the lungs and mediastinal lymph nodes and three of them had disseminated lesions in other organs. In all cattle acid-fast bacilli were observed in the lesions and marked positive for immunohistochemistry with polyclonal antibody anti-Mycobacterium tuberculosis. It is concluded that bovine tuberculosis of central nervous system occurs sporadically in Paraíba, in cattle of different ages, most of them with disseminate lesions in other organs. The location of the lesions suggests that the agent invaded the brain by hematogenous route through the circle of Willis.(AU)
Descrevem-se seis casos de tuberculose no sistema nervoso central (SNC) em bovinos, no semiárido da Paraíba. Foram revisados os laudos de um total de 851 necropsias de bovinos realizadas no período de 2003 a 2016. Destes, 73 (8,6%) foram diagnosticados com tuberculose e seis apresentavam lesões no SNC. Três casos ocorreram em bovinos de até dois anos de idade e três em bovinos adultos. Três bovinos apresentaram exclusivamente sinais nervosos, dois tinham sinais respiratórios e perda de peso e um não apresentava nenhum sinal clínico. Macroscopicamente, em cinco bovinos, havia espessamento das leptomeninges do cerebelo, medula espinhal, ponte, obex, colículos e córtex, principalmente, na região basilar encefálica próxima ao polígono de Willis. Em apenas um bovino houve a presença de tubérculo único no cerebelo. Microscopicamente observou-se moderada a acentuada meningite e encefalite granulomatosa. Cinco bovinos apresentaram lesões pulmonares e nos gânglios mediastínicos e três deles tinham lesões disseminadas em outros órgãos. Em todos os bovinos foram encontrados bacilos ácido-álcool resistentes intralesionais e todos tiveram marcação positiva na técnica de imuno-histoquímica com anticorpo policlonal anti-Mycobacterium tuberculosis. Conclui-se que a tuberculose do sistema nervoso central de bovinos ocorre de forma esporádica na Paraíba, principalmente em bovinos com lesões disseminadas em outros órgãos. Sugere-se que a disseminação do agente ocorre pela via hematógena, possivelmente através do polígono de Willis.(AU)

Contexto: A meningoencefalite tuberculosa (MTB) é uma complicação de alta morbimortalidade, rara e temida da tuberculose primária em crianças, acometendo principalmente os lactentes e adolescentes. Diferentemente do que ocorre no acometimento no adulto, os casos pediátricos são, na maioria, diagnosticados quando estão em estágios avançados, o que é justificado pela baixa especificidade clínica e laboratorial da investigação na população desta faixa etária. Descrição do caso: Lactente masculino de sete meses de idade chegou ao serviço de referência de seu município com quadro arrastado de tosse, febre intermitente e dificuldade respiratória e, após exames laboratoriais e de imagem sugestivos de broncopneumonia, chegou-se ao diagnóstico clínico de tuberculose miliar com MTB. Durante a internação, já com tratamento instituído e recomendado pelo Ministério da Saúde e pela Organização Mundial de Saúde, o paciente evoluiu com comprometimento neurológico focal, apresentando melhora dos sinais após quatro dias de internação. Após alta, o paciente foi reavaliado, apresentando melhora clínica significativa. Discussão: A disponibilidade de métodos com alta especificidade e sensibilidade para o diagnóstico da tuberculose no lactente ainda é baixa, dificultando, assim, a prevenção de complicações em populações oligossintomáticas e com apresentação inespecífica. Observou-se, nesse caso, que, mesmo após o diagnóstico e a implementação do tratamento preconizado para MTB, o paciente evoluiu com discreta sequela neurológica (paresia de membro inferior esquerdo). Conclusão: Este estudo evidenciou a relevância do diagnóstico precoce e da implementação do tratamento adequado para evitar sequelas neurológicas que podem ser irreversíveis, determinando evolução clínica favorável.

We report a case of a 23-year-old female immigrant from China who was diagnosed with multidrug-resistant tuberculosis affecting her lung and brain, resistant to the standard first-line therapeutics and streptomycin. She was treated with prothionamide, moxifloxacin, cycloserine, and kanamycin. However, her headache and brain lesion worsened. After the brain biopsy, the patient was confirmed with intracranial tuberculoma. Linezolid was added to intensify the treatment regimen, and steroid was added for the possibility of paradoxical response. Kanamycin was discontinued 6 months after initiation of the treatment; she was treated for 18 months with susceptible drugs and completely recovered. To our knowledge, this case is the first multidrug-resistant tuberculosis that disseminated to the brain in Korea.

In Korea, tuberculosis is still common disease. Central nervous system tuberculosis can manifest in a variety of forms, including tuberculous meningitis, tuberculous cerebritis, tuberculoma, tuberculous abscess, and miliary tuberculosis. Although intra-axial tuberculomas are the more common type of CNS tuberculosis, extra-axial lesions are rarely encountered. En plaque tuberculoma is an extremely rare presentation of intracranial tuberculosis with mimicking primary or secondary meningeal neoplasia. We describe a rare case of an en plaque tuberculoma accompanied by tuberculous meningitis and tuberculomas.

An extra-pulmonary tuberculosis [EPTB] infection rate of 30% in Saudi Arabia remains above the global rate. A variable rate of infection in each province has been reported and the involvement of most organs has been cited. Nationwide collective data on the current trends of infection are scarce and the factors behind the increased rate of EPTB are perplexing. This review endeavors to shed light into the epidemiology of EPTB, various types of infections sites, geographical differences in the infection rate, known risk factors, and challenges in the diagnosis and management of EPTB in Saudi Arabia

Spinal intramedullary tuberculoma remains a very rare entity of central nervous system tuberculosis. This is the same with the coexistence of spinal intramedullary and intracranial tuberculomas that remains extremely rare with less than 20 cases reported at present. Authors describe this uncommon case by analyzing a 65-year-old female patient who had past history of kidney transplantation due to stage 5 chronic kidney disease and pulmonary tuberculosis on medication. The patient experiences progressive paraplegia and numbness on both lower extremities. Magnetic resonance imaging demonstrated an intramedullary mass at T9-10 level and multiple intracranial enhancing nodules. Microsurgical resection of spinal intramedullary mass was performed and the lesion was histopathologically confirmed as Mycobacterium tuberculosis. Efficient diagnosis and management of this rare disease are reviewed along with previously reported cases.

La afectación del sistema nervioso central es una de las localizaciones extrapulmonares de la tuberculosis con peor pronóstico. El retraso en el diagnóstico y tratamiento es uno de los factores relacionados con mayor tasa de mortalidad y secuelas. Se describe la "reacción paradojal" como un deterioro sintomático de grado variable, durante el tratamiento efectivo de la tuberculosis. El aumento de la resistencia del Mycobacterium tuberculosis a fármacos observado en los últimos años genera mayor preocupación ante la aparición de una reacción paradojal durante el tratamiento. Se presenta el caso de un niño con meningitis tuberculosa que, luego de un mes de tratamiento, presentó empeoramiento clínico y nuevas lesiones en la tomografía y resonancia magnética nuclear de cerebro. Se excluyeron patologías asociadas, se verificó que la toma de medicamentos haya sido supervisada, y la sensibilidad del bacilo a fármacos antituberculosos de primera línea fue confirmada. El paciente no requirió cambios en el esquema de tratamiento antituberculoso y se administraron esteroides para el alivio sintomático. La reacción paradojal durante el tratamiento antituberculoso es infrecuente y debida a una reacción de hipersensibilidad entre el huésped y el bacilo tuberculoso. Cuando aparece, se debe asegurar la efectividad y el cumplimiento del tratamiento administrado.
The central nervous system is one of the locations of extrapulmonary tuberculosis with worse prognosis. The delay in diagnosis and treatment is one of the factors associated with higher mortality and sequelae. The "paradoxical reaction" is described as a variable degree of symptomatic deterioration during the effective treatment of tuberculosis. The increased resistance of Mycobacterium tuberculosis to drugs observed in recent years generates greater concern about the emergence of a paradoxical reaction during treatment. The case of a child with tuberculous meningitis that after one month of treatment presented clinical worsening and new lesions in CT and MRI images of the brain is presented. Comorbidities were excluded, it was verified that taking drugs has been monitored, and the sensitivity of the bacillus to first-line antituberculosis drugs was confirmed. The patient required no change in the pattern of tuberculosis treatment and steroids were administered for symptomatic relief. The paradoxical reaction during antituberculosis treatment is rare and due to a hypersensitivity reaction between the host and the tuberculous bacillus. When it appears you must ensure the effectiveness and compliance of the treatment.

The conus medullaris is frequently affected by inflammatory and infectious lesions which many times are hardly differentiated because of the similarity of their clinical history and physical examination among the different etiologies. Magnetic resonance imaging presents high sensitivity in the detection of these lesions and plays a relevant role in the diagnosis as well as in the evolutive control of the condition. The present pictorial essay with selected cases from the archives of the authors' institution is aimed at demonstrating imaging findings which might help in the diagnosis of a specific etiology amongst inflammatory an infectious conditions and in the differentiation with diseases of neoplastic and vascular etiologies, for example. Findings such as enhancement pattern, presence of cysts, edema and involvement of other regions of the central nervous system are important for this differentiation, and may define a specific etiology as associated with clinical and laboratory tests findings.
O cone medular é frequentemente acometido por lesões de etiologia inflamatória e infecciosa, muitas vezes de difícil diferenciação devido a história clínica e exame físico semelhantes entre as diversas entidades. A ressonância magnética apresenta alta sensibilidade na detecção de lesões no cone medular e tem importante papel no diagnóstico e controle evolutivo. Este ensaio iconográfico com casos selecionados dos arquivos do nosso serviço tem como objetivo demonstrar achados de imagem que possam auxiliar no diagnóstico de uma etiologia específica entre as doenças inflamatórias e infecciosas e na diferenciação com doenças de outras etiologias como neoplasias e causas vasculares. Características como padrão de realce, presença de cistos, edema, além do acometimento de outras regiões do sistema nervoso central são importantes para esta diferenciação, podendo definir uma etiologia específica quando associadas ao quadro clínico e laboratorial.

O objetivo do presente artigo foi relatar a abordagem diagnóstica da tuberculose pleural, ganglionar, renal e do sistema nervoso central. A forma mais frequente entre essas formas de tuberculose no Brasil é a tuberculose pleural, cujo diagnóstico na prática clínica baseia-se no exame histopatológico, com uma alternativa relatada nos últimos anos: a dosagem da enzima adenosina desaminase. A maioria dos achados laboratoriais encontrados implica na condição paucibacilar dessas formas extrapulmonares
The objective of this study was to report the diagnostic approach to tuberculosis of the pleura, lymph nodes, kidneys, and central nervous system. In Brazil, the most common extrapulmonary form of tuberculosis is that afecting the pleura. In clinical practice, pleural tuberculosis is typically diagnosed on the basis of the histopathological examination. However, in recent years, the determination of adenosine deaminase levels has been used as an alternative. Most laboratory indings indicate that these extrapulmonary forms are paucibacillary

A tuberculose persiste como uma importante causa de morbidade e mortalidade mundial. Apesar de a forma pulmonar ser a apresentação mais importante e frequente, o acometimento extrapulmonar ocorre em aproximadamente 10-20% dos casos e em até 60% nos imunocomprometidos. Revisamos as principais manifestações clínicas dos mais importantes acometimentos extrapulmonares da tuberculose em nosso meio. O comprometimento pleural, ganglionar e urogenital são os mais comuns em nosso meio, além da importância do comprometimento do sistema nervoso central. A tuberculose costuma manifestar-se clinicamente como enfermidade subaguda a crônica, com sinais sistêmicos clássicos de febre baixa vespertina, emagrecimento e astenia, além daqueles que são dependentes do órgão afetado. Algumas dessas manifestações são revistas e descritas, lembrando, porém, que não existe quadro clínico patognomônico da enfermidade e que essa deve ser sempre lembrada no diagnóstico diferencial em nosso meio
Tuberculosis persists as a major cause of morbidity and mortality worldwide. Although the pulmonary form is more common and severe, the extrapulmonary form occurs in 10-20% of all cases and in up to 60% of cases in which the host is immunocompromised. This paper reviews the principal clinical manifestations of the most common types of extrapulmonary tuberculosis. Extrapulmonary tuberculosis most often afects the pleura, lymph nodes, urogenital system, and central nervous system, the last being the most common. In most cases, extrapulmonary tuberculosis is a clinically subacute or chronic disease, with symptoms speciic to the afected organ, as well as systemic signs, including a low fever, weight loss, and asthenia. Although some of these manifestations have been described, there is no pathognomonic clinical proile of the disease, which should always be included in the diferential diagnosis

Uruguay presenta baja prevalencia de tuberculosis, ubicándose en la etapa de control de la endemia. El tuberculoma cerebral representa el 1% del total de casos de tuberculosis en inmunocompetentes. Se presenta el caso clínico de una mujer, de 45 años, diabética tipo 2, con un cuadro clínico progresivo de paresia e hipoestesia braquial derecha y crisis epilépticas parciales simples. Estudios imagenológicos evidenciaron lesiones frontoparietales izquierdas, la serología para virus de inmunodeficiencia humana (VIH): negativa, la velocidad de eritrosedimentación: 24 mm/h; el PPD: 3 mm. Se realizó biopsia esteroatáxica. La anatomía patológica evidenció granulomas con necrosis caseosa y el cultivo Mycobacterium tuberculosis. Se comenzó tratamiento según pautas nacionales de la Comisión Honoraria de Lucha Antituberculosa, obteniéndose remisión clínica e imagenológica. La literatura revisada muestra que la demora en el diagnóstico en paciente inmunocompetentes es aproximadamente cuatro veces mayor que en inmunodeprimidos. La presentación clínica es inespecífica, siendo frecuentes la cefalea, la crisis epiléptica generalizada y hemiparesia. La RM es el estudio de mayor sensibilidad diagnóstica, no existiendo imágenes patognomónicas de tuberculoma. El tratamiento es médico; el tratamiento neuroquirúrgico se reserva para casos con hipertensión endocraneana y progresión bajo tratamiento médico. La respuesta al tratamiento se monitoriza con la remisión de los síntomas y el control imagenológico, destacándose la lenta resolución imagenológica.

OBJECTIVE: To identify prognostic factors predicting a fatal outcome in HIV-negative children with neurotuberculosis based on clinical, epidemiological, and laboratory findings. METHOD: The clinical records of all in-patients diagnosed with neurotuberculosis from 1982 to 2005 were evaluated retrospectively. The following prognostic parameters were examined: gender, age, close contact with a tuberculosis-infected individual, vaccination for bacillus Calmette-Guérin, purified protein derivative (PPD) of tuberculin results, concomitant miliary tuberculosis, seizures, CSF results, and hydrocephalus. RESULTS: One hundred forty-one patients diagnosed with neurotuberculosis were included. Seventeen percent of the cases resulted in death. The factors that were correlated with a negative outcome included lack of contact with a tuberculosis-infected individual, negative PPD reaction, coma, and longer hospitalisation time. A multiple logistic regression analysis was performed to identify which of these factors most often resulted in death. CONCLUSION: Coma at diagnosis, lack of tuberculosis contact, and a non-reactive PPD were the most important predictors of fatality in patients with neurotuberculosis.
OBJETIVO: Identificar elementos prognósticos para a letalidade da neurotuberculose na criança, a partir das manifestações clínicas, dados epidemiológicos e laboratoriais. MÉTODO: Registros de pacientes internados durante o período de 1982 a 2005 foram retrospectivamente avaliados. Os elementos prognósticos considerados foram: sexo, idade, história de contato íntimo com indivíduo com tuberculose, vacinação com o bacilo de Calmette-Guérin (BCG), teste tuberculínico (PPD), concomitância de tuberculose miliar, convulsões, resultados da análise do LCR e presença de hidrocefalia. RESULTADOS: 141 pacientes com diagnóstico de neurotuberculose foram incluídos. Dezessete por cento dos pacientes foram a óbito. Os fatores associados ao óbito foram história negativa de contágio, ausência de reatividade ao teste de PPD, coma e tempo de internação prolongado. Análise por regressão logística múltipla foi usada para investigar as relações entre os elementos prognósticos e o desfecho óbito. CONCLUSÃO: Os fatores prognósticos na previsão de óbito nos pacientes com neurotuberculose foram a presença de coma no momento do diagnóstico, a ausência de história de contágio e a ausência de reação ao PPD.
