ABSTRACT
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

Resumen La tuberculosis (TBC) cerebral o tuberculoma(s) sin meningitis es una enfermedad poco frecuente y de alta morbimortalidad. Presentamos el caso clínico de un lactante de 11 meses, previamente sano, que consultó por fiebre prolongada y síntomas neurológicos. La RM de encéfalo mostró múltiples imágenes micronodulares e hidrocefalia. El estudio de LCR para bacterias, hongos y micobacterias fue negativo. Se prescribió terapia empírica como una meningoencefalitis subaguda y tratamiento antituberculoso tetraconjugado y corticoesteroides. La confirmación del diagnóstico de TBC cerebral se realizó por biopsia de la lesión, con presencia de inflamación granulomatosa crónica necrosante y bacilos ácido-alcohol resistentes. Se enfatiza la importancia de considerar esta presentación de TBC en niños, y la necesidad de la búsqueda exhaustiva del agente etiológico en diferentes líquidos y tejidos, aun por métodos invasores.
Cerebral tuberculosis TB (tuberculomas) without meningitis is an uncommon disease with a high morbidity and mortality. We report on a case that illustrates the complexity of this clinical presentation. An 11 month old, previously healthy male infant was brought to the clinic due to fever present during the last 1.5 months, associated with loss of neurodevelopmental goals and signs of endocranial hypertension. CT scan of the skull revealed dilatation of the ventricular system with transependimary edema; MRI showed multiple intra- and extra-axial micronodular images and hydrocephalus. Studies of CSF (cyto-chemical analysis, staining, culture for aerobes, fungi, mycobacteria, and molecular tests for TB were negative). Empirical management for subacute meningoencephalitis was prescribed complemented with tetraconjugated treatment for TB and steroids. As there was no microbiological isolation, biopsy of a cerebellar lesion was performed, which revealed chronic necrotizing granulomatous inflammation and acid-alcohol resistant bacilli. The diagnosis of cerebral TB without meningeal involvement was confirmed. The objective of the present report is to emphasize the importance of considering this presentation of TB in children, to remark the need of exhaustive search for the etiologic agent by obtaining samples of the different fluids and tissues even if it implies recurring to invasive methods.

BACKGROUND: Miliary tuberculosis (TB) can cause diagnostic confusion for clinicians because its radiological appearance can resemble that of metastatic cancer. CASE REPORT: Here, we describe the case of a 72-yearold woman with miliary TB mimicking brain metastasis from renal cell carcinoma. The patient visited our clinic because of dysarthria and sluggish speech. A metastatic cancer such as renal cell carcinoma or brain tumor was suspected. However, the patient was diagnosed with miliary TB associated with multiple intracranial tuberculomas and a subsequent paradoxical response to anti-TB therapy. CONCLUSION: Clinicians should be aware that miliary TB can mimic metastatic cancer even in older people, especially in TB-endemic regions.

Background: Ethiopia is one of the countries that has high burden of all forms of tuberculosis and there is no published report on computerized tomography scan and/or magnetic resonance imaging of intracranial tuberculomas. Objective : to review the clinical, computerized tomography and/or magnetic resonance imaging features of intracranial tuberculoma. Methods: A retrospective review of patient's medical records of patients operated for intracranial mass that had computerized tomography and/or magnetic resonance imaging brain scans and had histopathological diagnoses, at Tikur Anbessa Specialized Hospital between January 2009 and June 2013.Results: Of 222 operated cases of intracranial mass subjected to histopathological test 29 (14.6%) were found to have tuberculomas, 28 (14.1%) had caseous necrosis and one was a tuberculous abscess, in 25 cases imaging was available for review and were included in the study . There were 15 males and 10 females with age range being 2 to 65 years and with the Median age being 13 years. Twenty patients had computerized tomography and five patients had magnetic resonance imaging. Seizure 15/25 (60%) and headache 11/25 (44%) were the commonest presentation. Solitary or confluent large lesions were seen in 12/25 (48%) of patients. 14/25 (56%) of the lesions had their size between 2 cm and 5 cm. Majority of the lesions 15/25 (60%) were in the frontal and parietal lobes. The lesions were isodense on CT in 18/25 (72%) of the pre-contrast studies and 21/25 (84%) showed ring or rim enhancement after intravenous administration of the contrast medium.Conclusion: Tuberculoma, more frequently, presented with non-specific clinical findings and chronic seizure disorder and commonly occurred in young patients and often seen infratentorialy. It is often complicated with hydrocephalus in the pediatric age group. Computerized tomography scan and/or magnetic resonance imaging features are not different from reports from other countries

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.

Reportamos el caso de una joven HIV negativa, con daño del sistema nervioso central de tipo miliar a nivel cerebral y sin enfermedad pulmonar. La tuberculosis puede afectar extensamente a sujetos inmunocompetentes y este fenómeno ha sido descripto en muchas series a los largo del tiempo. Ante la sospecha clínica, el seguimiento de un protocolo específico para confirmar el diagnóstico es de vital importancia para el temprano diagnóstico y correcto manejo de una situación que puede comprometer la vida y generar a largo plazo secuelas graves. Se presenta el caso por el reto diagnóstico que ha supuesto y rara presentación en paciente inmunocompetente.
ABSTRACT Tuberculosis with central nervous system involvement is an uncommon but very serious disease, with a frecuence of 1% of all cases of tuberculosis. We report the case of a young HIV negative woman, with central nervous system damage of the miliary type in the brain without lung disease. Tuberculosis can extensively affect immunecompetent subjects and this phenomenon has been described in many series over the time. In the presence of clinical suspicion, the follow-up of a specific protocol to confirm the diagnosis is of vital importance for the early diagnosis and correct management of a situation that can compromise life and generate long-term serious sequelae. The case is presented because of diagnostic challenge and a rare presentation in an immunocompetent patient.

Tuberculosis is a chronic bacterial infection caused by Mycobacterium tuberculosis. Despite advances in treatment, resistant strains and unusual sites of involvement have been diagnosed. We present a case of a 13-year-old patient in treatment for tuberculous meningitis who presented with progressive paraparesis. The MRI showed two intramedullary nodular lesions at T4T6 levels, isointense with annular hyperintensity on T1W, hypointense on T2W, becoming hypointense with ring enhancement after contrast. These characteristics differ from those usually described for intramedullary tuberculomas. Surgical excision was performed, confirming the diagnosis of intramedullary tuberculoma. The formation of intramedullary tuberculomas is rare, with a ratio of two cases per thousand diagnosed with CNS tuberculosis, and the thoracic spine is most frequently affected. The clinical picture is of progressive subacute spinal cord compression, and it may lead to paraplegia. At MRI, the lesion in early stage appears as hypointense rings on T1W and hyperintense on T2W, with homogeneous enhancement after contrast. After the formation of the solid caseous granuloma, it becomes isointense on T1W and hypointense on T2W with homogeneous enhancement after contrast. When the center of the granuloma becomes liquefied, it shows hypointense sign on T1W and hyperintense with peripheral enhancement on T2W. The treatment of choice is medical, with the current protocol including rifampin, isoniazid, pyrazinamide, and ethambutol. Surgery is reserved for cases of progressive neurologic deficits or for diagnostic confirmation. Although benign and potentially curable, intramedullary tuberculoma should be promptly diagnosed and treated to prevent irreversible damage.
A tuberculose é uma infecção bacteriana crônica causada pelo Mycobacterium tuberculosis. Apesar dos avanços no tratamento, cepas resistentes e locais incomuns de envolvimento vêm sendo diagnosticados. Apresentamos o caso de um paciente de 13 anos de idade, em tratamento para meningite tuberculosa que se apresentou com paraparesia progressiva. A ressonância magnética mostrou duas lesões nodulares intramedulares no nível de T4T6, isointensas com bordos hiperintensos em T1, hipointensos em T2, tornando-se hipointensos com realce anelar após contraste. Essas características diferem daquelas usualmente descritas para tuberculomas intramedulares. Foi realizada a excisão cirúrgica, confirmando o diagnóstico de tuberculoma intramedular. A formação de tuberculomas intramedulares é rara, com uma proporção de dois casos por mil diagnosticados com tuberculose do sistema nervoso central (SNC), e a coluna torácica é a mais frequentemente acometida. O quadro clínico é de compressão da medula espinal progressiva subaguda, podendo levar à paraplegia. Na ressonância magnética, a lesão em fase inicial aparece como anéis hipointensos em T1 e hiperintensos em T2, com realce homogêneo após contraste. Após a formação do granuloma caseoso sólido, torna-se isointensa em T1 e hipointensa em T2, com realce homogêneo após contraste. Quando o centro do granuloma torna-se liquefeito, mostra sinal hipointenso em T1 e hiperintenso com realce periférico em T2. O tratamento de escolha é medicamentoso, com o protocolo corrente de rifampicina, isoniazida, pirazinamida e etambutol. A cirurgia é reservada para os casos de déficit neurológico progressivo ou para confirmação diagnóstica. Embora benigna e potencialmente curável, deve ser diagnosticada e tratada para evitar danos irreversíveis.

OBJECTIVE: Spinal intramedullary tuberculoma (SIMT) is rare, accounting for 2/100,000 cases of tuberculosis and only 0.2% of all cases of central nervous system(CNS) tuberculosis. We share our experiences of 11 cases of this entity for improving diagnosis and conceptualize the management of this rare disease. METHODS: The clinical profile, radiological data and management of 11 cases of SIMT which were managed either conservatively or by surgical intervention during last 27 years (1987-2014) were analysed. RESULTS: Male:female ratio was 1.75:1. Five cases had associated pulmonary Koch's. Most common site was thoracic cord. Two cases had concurrent multiple intracranial tuberculoma. Most common presentation was paraparesis. X-ray myelography was performed in two patients in the initial period of study suggesting intramedullary pathology. In the subsequent nine cases who had magnetic resonance imaging (MRI), seven showed typical "target sign" and conglomerate ring lesion. Out of 8 surgically managed patients, 6 cases improved rapidly and in 2 patients gradual improvement was seen in follow-up. Most common indication of surgical excision was rapid neurological deterioration followed by diagnosis in doubt. Histopathology confirmed tuberculous etiology of the intramedullary lesion in all. Clinical and radiological improvement was seen in all 3 conservatively managed patients in follow-up. CONCLUSION: MRI findings of SIMT were specific and proven histologically correct. Surgical intervention may be indicated if there is no response to chemotherapy, the diagnosis is in doubt, or there is a rapid deterioration in neurological function because surgical outcome is good in these circumstances.

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.

Tuberculosis is an important public health problem. It is estimated that around 5-10% of patients with tuberculosis present with central nervous system involvement; meningitis and tuberculoma being two of the most frequent manifestations. The paradoxical reaction in patients undergoing antituberculosis treatment is infrequent, nevertheless it is an important consideration in patients, who after an appropriate initial response to specific treatment, present with worsening clinical and radiological signs or the appearance of new lesions.
La tuberculosis (TBC) es un problema de importancia en salud pública. Se estima que alrededor de 5 a 10% de los pacientes con TBC presentan compromiso de sistema nervioso central, siendo la meningitis y el tuberculoma las manifestaciones más frecuentes. La reacción paradojal en pacientes con tratamiento antituberculoso es infrecuente, sin embargo, es importante considerarla en pacientes que durante la terapia, luego de una respuesta inicial apropiada, presentan un empeoramiento clínico y/o radiológico o aparición de nuevas lesiones.

Many cases are being reported before the Forensic Experts, in which it becomes difficult to find out the precise cause of death. A 73 year male was brought for autopsy examination at Rajendra Institute of Medical Sciences, Ranchi, Jharkhand with suspicion of death due to brain tumor. The findings of autopsy examination was edema of brain matters and depressed area in right frontal lobe of brain with several stitches marks on right side of head. Detailed history from all the concerned persons were taken which reveals previously person was operated by neurosurgeon for space occupying lesion in cranial cavity. Histo-pathology examination of mass showed Koch’s lesion as tuberculoma en plaque a very rare presentation of tuberculosis which is very common in our country even in the era of 21st century. Case is being presented with brief discussion showing the need of early and prompt history taking including hospital records details before an autopsy examination. It may reveal important facts as well as helps the Forensic Experts to take the consideration of therapeutic artefacts during autopsy to find the exact cause of death.

Brain tuberculomas account for 10-20% of space occupying brain lesions in developing countries. Most lesions are observed at time of tuberculosis diagnosis or soon after starting treatment. We herein describe a 32 year-old patient with a 14-month history of headache and progressive visual loss. Her past medical history revealed pulmonary tuberculosis treated eight years before. A brain MRI showed a T1- and T2-weighted isointense contrast-enhancing lesion in the optic chiasm. A presumptive diagnosis of optochiasmatic tuberculoma was made and isoniazid, rifampin, pyrazinamide, and ethambutol were started. Despite treatment, the patient evolved to blindness. The prompt recognition of this condition is extremely important since the presence of optochiasmal enhancement is associated with blindness in patients with tuberculosis.
Tuberculomas cerebrais são responsáveis por 10-20% das lesões parenquimatosas em países em desenvolvimento. A maioria destas lesões é observada ao diagnóstico de tuberculose ou logo após o início do tratamento. Descrevemos um caso de uma paciente de 32 anos com história de 14 meses de evolução de perda visual progressiva e cefaleia. A história patológica revelou tuberculose pulmonar 8 anos antes. A ressonância magnética do crânio mostrou uma lesão isointensa nas sequências T1 e T2 captantes de contraste no quiasma óptico. Fizemos o diagnóstico presuntivo de tuberculoma ótico-quiasmático e inciamos isoniazida, rifampicina, pirazinamida e etambutol. Apesar do tratamento, a paciente evoluiu para amaurose bilateral. O rápido diagnóstico desta condição é extremamente importante já que a presença de captação de contraste está associada à amaurose em pacientes com tuberculose.

The awake craniotomy is a procedure where the craniotomy and excision of the lesion is done in awake patient without general anaesthesia. This surgical technique enable surgeons to avoid damaging normal cerebral regions and allow real-time patient feedback while operating on important functional areas of brain like motor cortex and speech areas (motor, somatosensory, and language areas). Such surgical interventions would not be possible without anesthesia. This technique was originally introduced for the surgical treatment of epilepsy and has subsequently been used in patients undergoing surgical management of supratentorial tumours, deep brain stimulation and near critical brain regions. This surgical approach aims to maximize lesion resection while sparing important areas of the brain.

We report a case of isolated homonymous hemianopsia due to presumptive cerebral tubercular abscess as the initial manifestation of human immunodeficiency virus (HIV) infection. A 30-year-old man presented to our outpatient department with sudden loss of visibility in his left visual field. He had no other systemic symptoms. Perimetry showed left-sided incongruous homonymous hemianopsia denser above the horizontal meridian. Magnetic resonance imaging revealed irregular well-marginated lobulated lesions right temporo-occipital cerebral hemisphere and left high fronto-parietal cerebral hemisphere suggestive of brain tubercular abscess. Serological tests for HIV were reactive, and the patient was started only on anti-tubercular drugs with the presumptive diagnosis of cerebral tubercular abscess. Therapeutic response confirmed the diagnosis. Atypical ophthalmic manifestations may be the initial presenting feature in patients with HIV infection. This highlights the need for increased index of suspicion for HIV infection in young patients with atypical ophthalmic manifestations.

There is evidence that medically treated Tuberculoma patients have a significantly better functional recovery than those having surgical excision. This would not be possible theoretically unless strict diagnostic criteria are applied and if there is still doubt, resort to surgical excision or biopsy so that patient' health is not jeopardized. To evaluate the Effectiveness of Conservative management of Tuberculoma of Brain based on strict Diagnostic Criteria. Prospective Study. This study was conducted at Assir Central Hospital Abha KSA from March 2001 to August 2003. Out of total thirteen patients, Eight Patients presented with signs of raised intracranial tension [Headache, Vomiting], Two with localizing symptoms or signs [Hemiparesis and Diplopia], Two with history of Fever, Night sweats, Cough, and had been receiving immunosuppressive agents. One pregnant patient presented with history of convulsions on term. Three patients had Solitary and Ten patients Multiple Lesions. Maximum number of Lesions in our cases were Eleven and minimum was one. Patients were diagnosed based on Strict Criteria like Blood Smears, ESR, CRP, Acid-fast Bacillus in Sputum smears, CSF serology X-ray Chest, Contrast- enhanced CT and MRI. Failure of medical treatment occurred in two patient. One pregnant patient was operated due to intractable Epilepsy following caesarian section on term. The patients were followed for six months to Two years without recurrence. Diagnostic Criteria helped us to filter out TB Positive cases as against Bacterial, fungal and actinomycotic infections of brain. Conservative management alone was successful in the Treatment of Tuberculoma of Brain

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.
