Intracisternal tuberculoma: a refractory type of tuberculoma indicating surgical intervention.

BACKGROUND: Central nervous system (CNS) tuberculoma is a rare disease with severe neurological deficits. This retrospective research is to review the data of patients diagnosed as CNS tuberculoma. Surgeries were performed in all patients. The clinical features especially the neurological image and the anatomical characters of the tuberculomas were concerned. METHODS: Totally 11 patients diagnosed as CNS tuberculoma were admitted in Guangzhou First People's Hospital (7cases) and Changzheng Hospital (4 cases) during 2006-2015. The data including preoperative condition, neurological imaging, and surgical findings was collected and analyzed. RESULTS: The lesions of nine patients (9/11) were totally or subtotally excised and two (2/11) were partially excised. Neurological functions of all patients were improved after surgery without secondary infection. Lesions of nine (9/11) patients preoperatively progressed as a result of paradoxical reaction. Of the 9 patients demonstrated paradoxical progression, all lesions were partially or totally located at the cisterns or the subarachnoid space. Preoperative ATTs lasted 2 to 12 months and tuberculomas were not eliminated. The arachnoid was found thickened and tightly adhered to the lesions during surgeries. Of the 2 cases that paradoxical reaction were excluded, both patients (case 6, intramedullary tuberculoma; case 11, intradural extramedullary tuberculoma) were admitted at onset of the disease. ATTs were preoperatively given for 1 week as neurological deficits aggravated. The tuberculous lesions of CNS or other system showed no obvious change and paradoxical reaction could not be established in both cases. CONCLUSIONS: Exudates of tuberculosis is usually accumulated in the cisterns and frequently results in the paradoxical formation of tuberculoma. Intracisternal tuberculoma is closely related to paradoxical reaction and refractory to anti-tuberculosis therapy. Micro-surgical excision is safe and effective. Early surgical intervention may be considered in the diagnosis of intracisternal tuberculoma especially when paradoxical reaction participates in the development of tuberculoma.

Tuberculoma masked by glioma: a case report.

Tuberculous meningitis (TM), a common infectious disease of the central nervous system that is also seen in other types of tuberculosis infections, has higher mortality rates in young and middle-aged patients. TM is difficult to diagnose and treat owing to its non-specific clinical features and often atypical cerebrospinal fluid changes. Patients who present with focal neurologic signs, cough, low-grade fever and illness duration of more than 5 days, have intracalvarial abnormalities, and do not meet Thwaites' criterion findings should be diagnosed using computed tomography or magnetic resonance imaging. Mycobacterium infections can also be diagnosed by acid-fast staining of smears, cerebrospinal fluid culture, diagnostic polymerase chain reaction for Mycobacterium tuberculosis, and purified protein derivative test. To prevent TM misdiagnosis, clinicians must have sufficient knowledge of the clinical manifestations of tuberculosis. Appropriate application of tuberculosis chemotherapy drug principles, including early diagnosis and treatment, combination therapies, and consistent administration of treatment at appropriate dosages, can greatly reduce TM mortality rates and improve satisfactory treatment outcomes.

A large tuberculosis abscess causing spinal cord compression of the cervico-thoracic region in a young child.

INTRODUCTION: Despite numerous descriptive publications, the guidelines for treatment of cervical spinal tuberculosis (TB) are not very clear. The authors report a case of a young girl with cervico-thoracic spinal TB extending from C5 to T3 vertebrae presenting with weakness of the right hand and unsteady gait. CASE REPORT: An 11-year-old female who is an immigrant to the UK from Afghanistan, presented to our clinic with a 10-day history of difficulty in walking with an unsteady gait and 3-month history of progressive weakness in both her arms, the right side more affected than the left. Her immunisation history was unclear. Examination of the arms showed bilateral thenar and hypothenar wasting, more so on the right than the left. An MRI scan revealed a large para-spinal abscess extending from C3/4 to T4/5 with a significant anterior epidural cord compression from C5/6 to T2/3. Therapeutic/diagnostic aspiration was performed under ultrasound guidance and the aspirate was sent for microbiology. She was started empirically on multidrug anti-tubercular treatment and steroids. Although Ziehl-Neelsen stain was negative for acid-fast bacilli, microbiological confirmation of TB was obtained by positive TB culture sensitive to all first-line anti-TB drugs. She made a dramatic improvement within 3 weeks of anti-tubercular treatment. A follow-up MRI scan at 8 months showed complete resolution of the abscess. At 2 years of follow-up, she was a healthy looking child, back to her school with no residual clinical signs/symptoms of the disease. CONCLUSION: Our case of cervico-thoracic tuberculous abscess in a young child suggests that even with incomplete neurological deficit caused by epidural cord compression, ultrasound (or CT)-guided aspiration and anti-tubercular medication provide acceptable results at 2 years of follow-up.

Cystic pulmonary tuberculoma.

Pulmonary tuberculosis (TB) is a medical and social problem, particularly in developing countries. Early diagnosis and treatment is important. Chest radiography is usually the first diagnostic tool when there is a suspicion of pulmonary TB. A computed tomography (CT) scan provides more accurate information on the extent and distribution of pulmonary TB. We present here a young, immunocompetent male patient with unusual imaging findings for pulmonary TB. We discuss the clinical presentation and management.

Intradural extramedullary tuberculoma mimicking en plaque meningioma.

In this paper we report an 18 year old woman with an intradural extramedullary tuberculoma mimicking en plaque meningioma located in the thoracic region. The patient was operated via thoracic laminoplasty and tumor was totally resected. On the follow-up examination the magnetic resonance imaging demonstrated the total excision of the tumor. Here we describe a case of intradural extramedullary tuberculoma of the spinal cord as a complication of tuberculosis meningitis in a previously healthy young female.

[Extramedullary intradural tuberculosis: a case report and review of the literature]. / Tuberculoma intradural extramedular: descripcion de un caso clinico y revision de la bibliografia.

INTRODUCTION: Central nervous system tuberculosis is a common chronic infection in developing countries, being the most frequent forms: tuberculous meningitis and intracranial tuberculosis. Extramedullary intradural tuberculosis is a rare entity with few cases described in the world literature, and is usually associated with a history of tuberculous meningitis or during antituberculosis treatment. CASE REPORT: A 17 years-old male patient, without history of tuberculosis, with subacute onset and progressive course of compressive myelopathy. Spinal magnetic resonance imaging revealed an intradural extramedullary mass lesion between the C4 and T8 spinal levels. Surgical resection of tuberculoma was realized, followed by chemotherapy. The histopathological study confirmed the diagnostic. CONCLUSIONS: Tuberculosis of the central nervous system is an entity of high incidence in developing countries, and intradural extramedullary tuberculoma should be included in the differential diagnosis of expansive spinal cord injuries, especially if the patient is young and there is a history of pulmonary tuberculosis or tuberculous meningitis. It is also important to take it into account as part of a paradoxical reaction after the initiation of specific treatment. Although surgical resection improves compressive medullary symptoms, medical therapy remains the mainstay in the treatment of tuberculomas.

TITLE: Tuberculoma intradural extramedular: descripcion de un caso clinico y revision de la bibliografia.Introduccion. La tuberculosis del sistema nervioso central es una infeccion cronica comun en paises en vias de desarrollo, y la meningitis tuberculosa y los tuberculomas intracraneales son las formas mas frecuentes. El tuberculoma intradural extramedular es una entidad poco frecuente, con pocos casos descritos en la bibliografia mundial, y por lo general se asocia a un antecedente de meningitis tuberculosa o durante el tratamiento antituberculoso. Caso clinico. Varon de 17 años, sin antecedente de tuberculosis, con cuadro clinico de una mielopatia compresiva de aparicion subaguda y curso progresivo, cuya neuroimagen evidencio una lesion extensa intradural extramedular. Se le realizo cura quirurgica mas laminectomia descompresiva en D4-D8 seguido de quimioterapia. El estudio histopatologico confirmo el diagnostico. Conclusiones. La tuberculosis del sistema nervioso central es una entidad de alta incidencia en nuestro medio, y el tuberculoma intradural extramedular deberia incluirse en el diagnostico diferencial de lesiones expansivas de la medula espinal, mas aun si el paciente es joven y existe el antecedente de tuberculosis pulmonar o meningitis tuberculosa. Asimismo, es importante tenerla en cuenta como parte de una reaccion paradojica despues del inicio del tratamiento especifico. Aunque la reseccion quirurgica mejora los sintomas compresivos medulares, la terapia medica continua siendo el pilar en el tratamiento de los tuberculomas.

A case of hepatic tuberculosis: A tuberculoma.

Tuberculosis (TB) is a common cause of morbidity and mortality worldwide and its eradication in the United States has stalled for the first time in decades. Isolated hepatic TB is an extremely uncommon form of extrapulmonary TB. Here we present a case of a tuberculous liver abscess and suggest that TB should be considered in patients who fail to respond to antibiotics and prompt diagnostic intervention.

Successful management of tubercular subretinal granulomas.

PURPOSE: To report the successful management of 12 eyes of 11 patients with tubercular subretinal granulomas. METHODS: Eleven consecutive patients with a presumed or confirmed diagnosis of tubercular subretinal granulomas were treated with four-drug anti-tuberculosis chemotherapy with concomitant oral corticosteroids. Two patients underwent pars plana vitrectomy. RESULTS: The study included seven males and four women with a median age of 30.5 years. Ten eyes responded well to medical management and a final visual acuity of 20/80 or better was achieved in eight of them. The eyes subjected to pars plana vitrectomy had a relatively worse outcome. CONCLUSIONS: Tubercular subretinal granulomas are amenable to medical management provided an early diagnosis is made and treatment is initiated promptly. Once the diagnosis of presumed or confirmed tuberculosis is established, surgical intervention should be avoided.

Intradural extramedullary tuberculoma of the spinal cord: a review of reported cases.

Intradural extramedullary tuberculoma of the spinal cord (IETSC) is a rare modality of tuberculosis, with only a few cases described so far. Here we review 22 reports of the disease found in the literature of the last 25 years. IETSC is closely associated with tuberculous meningitis (TM). Both conditions may occur simultaneously, but more frequently IETSC is preceded by TM. IETSC has been described in a predominantly young population of both genders. The pathogenesis is unknown, although a paradoxical reaction to antituberculous medication is a reasonable possibility. The disease presents insidiously with paraparesis, hypoesthesia with a sensory level, and bladder dysfunction, due to cord involvement or compression by the inflammatory process. Permanent paraparesis is a common sequela. MRI is the diagnostic technique of choice in IETSC. Prompt surgical excision of the tuberculoma is the cornerstone of therapy. Antituberculous treatment is also indicated; unless resistance is present, conventional chemotherapy is probably enough. Corticosteroids are also generally recommended. In conclusion, IETSC is a rare complication of TM, which presents insidiously, despite adequate antituberculous treatment. To avoid the permanent disability that this condition may provoke, an early diagnosis and prompt treatment is critical.

Brain Tuberculoma as a Differential Diagnosis of Single Intracranial Lesion: Case Report

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.

Brain-stem tuberculoma. An analysis of 11 patients.

The clinical and radiologic findings in 11 patients with brain-stem tuberculoma were reviewed. Clinical manifestations included various combinations of focal signs and symptoms of subacute onset, similar to those produced by other space-occupying lesions of the brain stem. Evidence of systemic tuberculosis was found in six cases (55%). Computed tomography (CT) usually showed an isodense or hyperdense brain-stem mass with abnormal contrast enhancement; associated supratentorial granulomas were found in four cases, and hydrocephalus was found in two cases. Magnetic resonance imaging showed irregular brain-stem lesions with long T1 and short T2 relaxation times. Cerebrospinal fluid findings were also nonspecific, as smears for acid-fast bacilli were most often negative. An incorrect diagnosis of pontine glioma was made in one patient. In contrast, proper integration of data from CT and magnetic resonance imaging findings, cerebrospinal fluid analysis, and x-ray films of the chest permitted an accurate diagnosis in ten cases. Prompt therapy with antituberculous drugs resulted in clinical improvement, documented by CT, in most patients. Brain-stem tuberculoma should be suspected in patients with space-occupying lesions of the brain stem who live in geographic areas where tuberculosis is endemic. Early diagnosis and prompt medical therapy are important in preventing mortality and reducing morbidity.

Intracranial tuberculoma: conservative management.

Twenty cases of intracranial tuberculoma were treated by us. A clinical-radiographic syndrome was recognized, consisting of an avascular enhancing mass lesion surrounded by marked edema and associated with relatively less severe clinical manifestations than would have been expected from the size and location of the lesion. This allowed successful medical therapy with three antituberculous drugs for an average of 12 months. Steroids, when used, were beneficial in relieving symptoms of cerebral edema without causing spread of tuberculosis. Medically treated patients had a significantly better functional recovery than those from whom the tuberculoma was excised.

Tuberculoma of the anterior optic pathways. Case report.

A tuberculoma, encasing the anterior optic pathways in a neoplastiform growth, was found in a 25-year-old man complaining of severe visual loss, diabetes insipidus, and sexual impotence following tuberculous meningitis. Following biopsy and anti-tuberculosis treatment, a satisfactory restoration of sight in one eye allowed the patient to resume an almost normal life.

Spinal tuberculosis: a diagnostic and management challenge.

The authors reviewed 29 cases of spinal tuberculosis treated from 1973 to 1993 with an average follow-up time of 7.4 years. Clinical findings included back pain, paraparesis, kyphosis, fever, sensory disturbance, and bowel and bladder dysfunction. Twenty-two patients (76%) presented with neurological deficit; 12 (41%) were initially misdiagnosed. Sixteen patients (55%) had predominant vertebral body involvement; nine had marked bone collapse with neurological compromise. Eleven individuals (39%) had intraspinal granulomatous tissue causing neurological dysfunction in the absence of bone destruction, and two (7%) had intramedullary tuberculomas. All patients received antituberculous medications: 13 were initially treated with bracing alone, eight underwent laminectomy and debridement of extra- or intradural granulomatous tissue, and eight underwent anterior, posterior, or combined fusion procedures. No patient with neurological deficit recovered or stabilized with nonoperative management. Thirteen patients were readmitted with progression of inadequately treated osteomyelitis; 12 (92%) of these required new or more radical fusion procedures. Anterior fusion failure was associated with marked preoperative kyphosis and multilevel disease requiring a graft that spanned more than two disc spaces. Courses of antibiotic medications shorter than 6 months were invariably associated with disease recurrence. It was concluded that 1) patients should receive at least 12 months of appropriate antituberculous therapy; 2) individuals with neurological deficit should undergo surgical decompression; 3) laminectomy and debridement are adequate for intraspinal granulomatous tissue in the absence of significant bone destruction; 4) when vertebral body involvement has produced wedging and kyphosis, aggressive debridement and fusion are indicated to prevent delayed instability and progression of disease.

Intracranial tuberculomas: a CT study.

CT appearances of 25 tuberculomas are described. The image morphology of the immature forms is small discs and rings with massive oedema. The mature forms appear as large rings or lobulated masses. The large rings enclose a mass, a little more dense than brain; the lobulated masses represent coalesced small discs and rings forming a large tuberculoma. These images are consistent and repetitive in tuberculomas. The larger masses form the surgical group and need excision; the smaller masses form the medical group and have had successful medical therapy with serial scans to document healing. The presence of multiple masses is recorded in 55% of the cases.

Intramedullary spinal tuberculoma: a case report.

STUDY DESIGN: A case report showing an intramedullary thoracic spinal tuberculoma secondary to pulmonary tuberculosis in a 16-year-old patient with findings of subacute spinal cord compression. OBJECTIVES: The significance and the use of magnetic resonance imaging in the diagnosis of intramedullary tuberculoma, and the treatment of the patient that involves surgically the excision of intramedullary lesion followed by appropriate antituberculous therapy. SUMMARY OF BACKGROUND DATA: Tuberculomas of spinal cord are rare entities. The possibility of intramedullary tuberculoma should be seriously considered when an intraspinal mass is found, provided that pulmonary tuberculosis is present in the history of the patient. METHOD: Th4-Th5 laminectomy was performed. Intramedullary tuberculoma was excised through a myelotomy. Antituberculous treatment was applied after the surgery. RESULTS: Excellent clinical outcome was obtained with a combination of both medical and surgical treatments. CONCLUSION: The intramedullary spinal tuberculoma, although a rare entity, must be considered in the differential diagnosis of the spinal cord compression in patients with a history of tuberculosis, human immunodeficiency virus, and those who have a bad socioeconomic condition and bad nutrition habit. When confronted with a progressing neurologic deficit, a combination of microsurgical resection and antituberculous chemotherapy with the avoidance of steroids should be the choice of treatment for intramedullary tuberculomas.

Intrasellar tuberculoma--an enigmatic pituitary infection: a series of 18 cases.

OBJECTIVE: Intrasellar tuberculomas are rare and only few case reports have been described in the literature. We report a series of 18 cases of histologically proven intrasellar tuberculomas, which, to the best of our knowledge, is the largest series in the English literature. METHODS: A total of 1143 pituitary lesions, between 1984 and June 1999, were operated for various reasons in our institute. Of these, 18 cases were histopathologically proven intrasellar tuberculomas. The clinical profile was reviewed in detail. Radiological data and histopathological slides were also reviewed. RESULTS: The age ranged from 8 to 43 years (average 23.6 years) with a female preponderance. The duration of symptoms varied from 15 days to 2 years (average 4 months), the most common symptoms being headache followed by decrease or loss of vision. Five patients had features of pan-hypopituitarism whereas three had raised prolactin (PRL) levels. In six patients, both sella as well as sphenoid sinus were involved. In one patient the lesion was extending from the sella over the clivus. Clinically as well as radiologically, these lesions were mistaken for pituitary adenomas except for one case where tuberculoma was suspected on imaging. In three patients, there was past history of pulmonary tuberculosis, in one patient of tuberculous meningitis, and in one patient, of spondilytis of the spine. In one patient there was cervical lymphadenopathy along with features of acromegaly (also proved by high levels of serum growth hormone) and radiology revealed a pituitary pathology. Microscopic examination of the excised lesion revealed a composite lesion consisting of a pituitary adenoma and tuberculoma, which has not been documented in literature to date. One patient died during the hospital stay. All the other patients were put on antitubercular chemotherapy following surgery and had good outcomes. CONCLUSION: Intrasellar tuberculomas are rare. These may be suspected in female patients especially if radiological imaging shows involvement of paranasal sinuses and pituitary fossa along with thickening of pituitary stalk. Simultaneous involvement of clivus may also be an additional feature. The incidence of pituitary tuberculosis is likely to increase with a rise in the incidence of AIDS.

Intramedullary tuberculoma: report of two cases with MRI findings.

Two cases of spinal intramedullary tuberculous granulomas (tuberculomas) without any bony involvement are reported. The rarity of the occurrence and the magnetic resonance imaging (MRI) findings are discussed. Microsurgical excision and antituberculous treatment produced good results.
