Abstract
CASE An 85-year-old woman was transported to our institution due to difficulty in walking. Preoperative imaging showed spinal cord lesions indicative of spinal cord tumor at the T7-8 level, accompanied by T8 vertebral fracture. Intraoperatively, the spinal lesion was suspected to be an epidural abscess; therefore, the capsule was resected, and the abscess was drained. We added pedicle screw fixation at the T6-10 level. Postoperatively, the spinal cord lesion was definitively diagnosed as spinal epidural tuberculoma. CONCLUSION Spinal epidural tuberculomas should be considered in the treatment of spinal cord lesions causing paralysis attributed to spinal cord compression.

Abstract
Tuberculosis of the hypothalamo-pituitary axis is extremely uncommon. The presentation of panhypopituitarism in a case of sellar tuberculosis is an even rarer occurrence. We present a case of a 44-year-old man who presented with complaints of headache and right-sided diminution of vision for six months. A hormone profile showed abnormal anterior pituitary assay suggestive of panhypopituitarism. Magnetic Resonance imaging of the brain showed a sellar mass measuring 1.8 × 1.5 × 1.3 cm with suprasellar extension suggestive of a pituitary adenoma. Histopathological examination showed multiple epithelioid cell granulomas along with Langhans giant cells and mixed inflammatory infiltrates against a necrotic background. Zeihl Neelson stain demonstrated the presence of acid-fast bacilli. Thus, a final diagnosis of pituitary tuberculoma was made, and the patient started on antitubercular therapy. It is extremely important to correctly diagnose sellar tuberculosis as the treatment is entirely different, and the patient usually responds well to therapy.

Abstract
INTRODUCTION Suprasellar tuberculoma are extremely rare in children and most of those patients present with headache, vomiting, visual disturbances, and hypofunction of the pituitary gland. In this case report, we present a girl with tuberculosis, who developed significant weight gain in combination with pituitary dysfunction, which recovered after antituberculosis treatment. CASE PRESENTATION An 11-year old girl presented with headache, fever and anorexia that progressively evolved into an encephalopathic status with cranial nerves III and VI paresis. Brain MRI showed meningeal contrast capture along cranial nerves II (including optic chiasm), III, V and VI bilaterally and multiple contrast enhancing brain parenchyma lesions. Tuberculin skin test was negative but interferon-gamma release assay was positive. The clinical and radiological working diagnosis was consistent with tuberculous meningoencephalitis. Pulse corticosteroids for 3 days and quadruple antituberculosis therapy were started and the girl demonstrated obvious improvement of her neurological symptoms. However, after a few months of therapy she developed remarkable weight gain (+20 kg in 1 year) and growth arrest. Her hormone profile revealed insulin resistance (homeostasis model assessment-estimated insulin resistance [HOMA-IR] 6.8) despite putative growth hormone deficiency (circulating insulin-like growth factor-I [IGF-I] 104 μg/L [-2.4 SD]). Follow-up brain MRI showed a decrease in basal meningitis, but increased parenchymal lesions in the suprasellar region extending medially into the nucleus lentiformis, with now a voluminous tuberculoma at this site. Antituberculosis treatment was continued for a total of 18 months. The patient improved clinically, she regained her pre-illness Body Mass Index (BMI) SDS and her growth rate increased slightly. On the hormonal side, disappearance of insulin resistance (HOMA-IR 2.5) and an increase in IGF-I (175 μg/L, -1.4 SD) was noted, and her last brain MRI showed a remarkable volume reduction of the suprasellar tuberculoma. CONCLUSION Suprasellar tuberculoma can have a very dynamic presentation during the active stage of the disease, which can be reversed by prolonged antituberculosis treatment. Previous studies showed that the tuberculous process can also cause long term and irreversible changes in the hypothalamic-pituitary axis. Prospective studies are however needed in the pediatric population to know the exact incidence and type of pituitary dysfunction.

Abstract
A 59-year-old woman with a diabetes history experienced mild neck pain. A neurological examination revealed only mild neck stiffness. Magnetic resonance imaging showed extensive T2-weighted high-intensity lesions with patchy gadolinium enhancement mainly involving the white matter in the right parietal lobe. A cerebrospinal fluid analysis revealed increased protein levels and pleocytosis. While QuantiFERON-TB Gold was positive, computed tomography (CT) and fluorodeoxyglucose on positron emission tomography-CT of the whole body showed no abnormal accumulation, suggesting tuberculosis. A brain biopsy revealed cerebral tuberculoma. As cerebral tuberculoma can show minimal neurological symptoms despite extensive lesions, a cautious examination and early treatment are required to prevent a devastating prognosis.

Abstract
ABSTRACT A 54-year-old woman was referred because of dizziness with fatigue for 2 months. MRI of the head and spinal cord revealed multiple ring or homogeneous enhancing nodules in the brain and spinal cord, concerning for metastases. FDG PET/CT showed multiple hypermetabolic nodules in the brain and spinal cord corresponding to the gadolinium-enhanced nodules and diffuse FDG uptake in the bilateral lower lobes of the lungs. Chest high-resolution CT showed diffuse, bilateral miliary opacities, most predominant in the lower lobes. The imaging findings and results of cerebrospinal fluid analysis were consistent with disseminated central nervous system tuberculomas with miliary pulmonary tuberculosis.

Abstract
RATIONALE Warthin's tumor is the second most common tumor arising from the parotid gland, but it rarely occurs concomitantly with tuberculous granulomatous inflammation with only 13 documented case reports in the English literature. PATIENT CONCERNS An 82-year-old woman had a left infraauricular mass for approximately 3 years that had significantly increased in size over the previous 1 month. DIAGNOSES A diagnosis of Warthin's tumor was made by ultrasonography (US)-guided core needle biopsy. Pathological examinations of the specimen obtained by total extirpation confirmed that the tumor was superimposed with tuberculous granuloma. INTERVENTIONS The core biopsy wound did not heal and there was formation of a skin fistula tract with persistent discharge. During the operation with en bloc resection of the necrotic parotid tumor, adhesion between the branches of the facial nerve was too tight to allow preservation. OUTCOMES A diagnosis of necrotic Warthin's tumor superimposed with tuberculous granuloma was made. Due to the high-clinical suspicion of tuberculosis (TB) due to Mycobacterium tuberculosis infection, anti-TB chemotherapy was given. LESSONS Poor wound healing from a core biopsy and formation of a skin fistulous tract with persistent discharge should raise concern regarding potential extrapulmonary tuberculous infection. Although very rare, tuberculous granuloma concomitant with Warthin's tumor should be considered in the differential diagnosis of a parotid mass lesion. Adhesion of branches of the facial nerve should be expected, and sacrifice of the nerve may be planned. This consideration can be explained to the patient in preoperative counseling and planning. Anti-TB chemotherapy should be given in cases with a definite pathological report associated with speculative clinical presentation.

Abstract
BACKGROUND To investigate the predictive value of plasma D-dimer levels for short-term therapeutic effect and progression-free survival (PFS) in patients with small-cell lung cancer (SCLC); and to analyze the correlation between baseline plasma D-dimer levels and other clinicopathological features. The aim of the study was to investigate whether the levels of plasma D-dimer could serve as a predictive and prognostic factor in patients with SCLC. METHODS A retrospective review of the clinicopathological data of 160 patients with pathologically confirmed SCLC, who were treated at the Department of Thoracic Oncology of Tianjin Medical University Tumor Institute and Hospital between June 2011 and June 2016, was performed. At the same time, we collected 100 patients with benign pulmonary diseases as a control group. The correlations between baseline plasma D-dimer levels and other clinical features, therapeutic effect and PFS were analyzed statistically. RESULTS The level of plasma D-dimer in patients with SCLC was significantly higher than that of patients with benign pulmonary diseases (P = 0.001). The PFS of patients with elevated D-dimer levels before therapy were significantly shorter than that of patients with normal D-dimer levels (6.0 versus 7.5 months, P = 0.013). The patients whose plasma D-dimer level always (before and after treatment) in the normal range have the best prognosis, and continuously elevated D-dimer carried out a poor prognosis (8.0 versus 5.0 months). According to multivariate analysis, elevated D-dimer level was confirmed to be an independent prognostic factor for worse survival (P = 0.029). The level of D-dimer was associated with tumor stage, the level of neuron-specific enolase, the presence of distant metastasis, hyponatremia, and the Karnofsky performance status score; and levels decreased when therapy was effective, but increased when the disease progressed. CONCLUSIONS High levels of baseline plasma D-dimer may indicate advanced disease stage and poor prognosis. Therefore, plasma D-dimer levels could serve as a predictive and prognostic factor in patients with SCLC.

Abstract
Tuberculosis is a public health problem in Morocco. Central nervous system involvement is nevertheless rare, occurring in the context of multifocal or miliary tuberculosis. However, it may be a mode of revelation even in an immunocompetent subject. We report the case of a 30-year old man with language disorder accompanied by significant impairment of general condition. Clinical examination showed Broca's motor aphasia, right-sided pyramidal syndrome and latero-cervical adenopathies. HIV serologic test was negative. Brain MRI showed lesions associating multiple intracranial tuberculomas and meningoencephalitis. Thoracic CT scan showed multiple pulmonary micronodules, cavity wall thickening and bronchiectasia of the right fowler and culmen. Lymph node biopsy revealed typical architecture of a TB granuloma. The diagnosis of multifocal tuberculosis was retained and the patient received anti-bacillary therapy associated with corticosteroid therapy with good clinico-radiological evolution. This study is peculiar due to the appearance and the seat of tuberculous lesions on brain imaging, the absence of immunodeficiency, a good evolution under treatment. It highlights the role of active and exhaustive assessment of associated extracerebral tuberculous infection in the case of cerebromeningeal lesion suggestive of tuberculosis.

Abstract
A 50-year-old woman presented with a headache and nausea. A sellar and suprasellar mass was detected on MRI; the tumor was heterogeneously enhanced with gadolinium, and the pituitary stalk was slightly thickened. Laboratory tests revealed severe growth hormone, luteinizing hormone, follicle-stimulating hormone and thyroid-stimulating hormone deficiencies. A pathological examination of the tumor showed scattered granulomas with central necrosis and Langhans giant cells. Tuberculin skin and QuantiFERON TB-Gold tests (QFT-2G) were positive. Accordingly, we diagnosed the patient with pituitary tuberculoma presenting with pituitary dysfunction. Following treatment with antituberculous drugs, the pituitary hormone function normalized and the pituitary tuberculoma disappeared.

Abstract
Isolated involvement of the ventricle by tuberculosis is extremely rare and only nine cases have been reported till now. We report a 13-year-old immuno-competent boy who presented with features of raised intracranial pressure with altered sensorium. Computed Tomography showed a ring enhancing intraventricular lesion with obstructive hydrocephalus. Gross total resection of the lesion was achieved and diagnosis was confirmed histologically. The patient had medical complications in the postoperative period and succumbs five days after the surgery. This report presents the unusual location of a common disease with a review of its clinical, radiological and histopathological features as well as the treatment modalities available.

Abstract
A 61-year-old woman who had received treatment for tuberculous pleurisy for 2 months visited our outpatient clinic. Chest computed tomography (CT) showed the presence of a lens-shaped pleural mass with pulmonary infiltration, despite the decreased pleural effusion. Two weeks later, chest CT showed an increase in the size of the mass and expansion of the intrapulmonary shadow. Percutaneous CT-guided lung biopsy was performed, and histopathological examination revealed granulomatous inflammation without caseous necrosis or acid-fast bacilli. Sputum culture was negative for acid-fast bacilli. Anti-tuberculosis medication was continued, and the lesions eventually resolved. These lesions were diagnosed as pleural tuberculomas, and the intrapulmonary infiltration was considered to be due to the paradoxical worsening of the patient's condition.

Abstract
A 27-year-old woman who had been treated for pulmonary tuberculosis with anti-tuberculosis drugs for three months was admitted to our hospital because of pain in the chest and back. Chest CT showed improvement in the pulmonary tuberculosis lesions in the right middle lobe and S8, but there was a large pleural mass in the right lower lung field. Histopathological findings of the percutaneous biopsy showed epithelioid cell granulomas that were negative for acid-fast bacilli. We diagnosed the mass as pleural tuberculoma with intrapulmonary invasion. The pleural tuberculoma improved without any additional therapy.

Abstract
The specific features of the pathogenesis of lung tuberculomas were studied in 302 patients among the indigenes and newcomers in the Far-North. The predominant formation of caseous foci from the tuberculous infiltrate located in the lung tissue in most cases was ascertained to be the specific feature of the development of lung tuberculomas under the conditions of a Far- North region, in Yakutia in particular. Tuberculoma formation shows a peculiar combination of evolving foci of acute specific pneumonia with a torpid inflammatory process, which contributes to the formation of multiple and large tuberculomas in the presence of significant pneumosclerosis. At the same time, homogeneous tuberculomas most commonly formed in both newcomers and indigenes.

Abstract
A 21-year-old woman was admitted to our hospital because of high fever, a productive cough and general fatigue. Her chest radiography scan revealed dense consolidation with air-bronchograms in the left lower lobe. Bacterial pneumonia was diagnosed and she was treated with antibiotics, although the specific cause could not be identified. After one month, a bronchoscopy was performed due to lack of improvement of consolidation in chest radiography. A smear examination of the bronchial washing specimen was positive for acid-fast bacilli (AFB) and Mycobacterium tuberculosis (MTB) was confirmed by PCR. After anti-tuberculous drugs (INH, RFP, EB, and PZA) were prescribed for 6 months, chest X-ray findings improved markedly. Two pleural tuberculomas were found in the left upper and lower lung fields 3 months after beginning therapy, and a new pleural tuberculoma appeared in the left upper lung fields 6 months after finishing therapy. Histopathological findings (HE stain) of a CT-guided needle lung biopsy showed epithelioid cell granulomas without caseous necrosis with multinuclear giant cells which were negative for acid-fast bacterium. All of the pleural tuberculomas improved without any additional therapy 18 months after finishing therapy. It was thought that such cases of multiple and metachronous pleural tuberculomas during the course of anti-tuberculous chemotherapy and follow-up of caseous pneumonia are rare. We suggest the possibility that the pleural tuberculomas were due to a paradoxical or hypersensitive reaction to the anti-tuberculous chemotherapy in this case.

Abstract
OBJECTIVE To investigate the clinical, pathological and radiological characteristics of pleural tuberculoma, so as to improve the understanding of this disease. METHODS We retrospectively analyzed the clinical, laboratory, pathological and radiological data of 83 cases of pleural tuberculoma diagnosed by pathology and(or) bacteriology in Shanghai Pulmonary Hospital Affiliated to Tongji University. RESULTS In the recruited 83 cases, there were 50 males and 33 females, aged from 7 to 85 years old, with a mean age of 37.8 years. Cough, fever and chest pain were common symptoms, but no significant symptoms were seen in 25 patients (31.3%). Some patients had positive physical signs, such as dullness to percussion and low breath sound. Pulmonary tuberculosis was also present in 36 patients (43.3%) with pleural tuberculoma. A history of tuberculous pleurisy was elicited in 80 patients, among whom 45 (56.3%) received delayed antituberculous treatment and 42 (52.5%) received nonstandard treatment. Forty-eight cases (60.0%) did not receive corticosteroids. Fifty-nine cases underwent CT-guided percutaneous biopsy, while 24 underwent thoracoscopic surgery, and tuberculosis was pathologically confirmed in 62 (74.7%). Pathological profiles included granuloma, coagulation or caseation necrosis, lymphocyte infiltration, epithelioid cells, inflammatory cells, histiocytes and scar tissue. Fifteen (18.1%) specimens from percutaneous biopsy were anti-fast smear positive, while Mycobacterium tuberculosis was obtained by culture in 21 (25.3%) cases. Chest X-ray showed that solitary lesions were seen in 68 cases, multiple foci in 15. The lesions of 46 cases (55.4%) occupied the lower right lobes. Round-like shadows were the most common signs, which were present in 63 cases (75.9%). CT examination demonstrated homogeneous density in 20, heterogeneous density in 40, calcification in 9, central attenuation in 34, and peripheral intensification in 28 cases. CONCLUSIONS Pleural tuberculoma is an important sequelae of tuberculous pleurisy. Understanding its clinical, pathological and radiological characteristics is helpful for the differential diagnosis of pleural and lung diseases.

Abstract
Cardiac tuberculosis is rare and usually involves the pericardium. Myocardial tuberculoma is a very rare occurrence and only a few cases were reported. We describe the use of cardiovascular magnetic resonance in the diagnosis of a rare case of cardiac tuberculoma involving the right atrium which was complicated by a bicaval obstruction. The patient made a remarkable improvement with the anti-tuberculous treatment. To our knowledge, this complication has never been reported in relation to cardiac tuberculoma.

Abstract
Tuberculosis is a chronic infectious disease predominantly affecting the lung. The hallmark of tuberculosis infection is the formation of granulomata in the vicinity of infectious foci. The tuberculous granuloma is a complex, cellulary and biochemically well-orchestrated structure, which development plays a dual role. Restricting dissemination of infection and forming a battlefield for protective immunity, granulomatous process may compromise lung function, threatinig the host health. Both the susceptibility to infection per se and the degree of lung failure and disease severity are under genetic control. Tuberculosis genetics is complex and far from being resolved, but the information available clearly indicates that the control of intracellular infections depends upon biochemical networks, which have not been appreciated with this regard until recently.

Abstract
Intradural extramedullary tuberculoma of the spinal cord (IETSC) is a rare complication of tuberculosis, which can occur as a paradoxical response to antituberculous therapy. A 46-year-old woman with tuberculosis meningitis developed an acute sensory disturbance and paraplegia eight weeks after the antituberculous treatment was started. MRI revealed a cystic lesion at the Th 2 and 3 vertebrae levels, and continuous dural thickening. Laminectomy was performed; soft granulomas were unexpectedly observed inside the dura matter. After the operation, the patient experienced progressive improvement in motor strength. IETSC should be known as rare but possible complication of tuberculous meningitis.

Abstract
The large reservoir of human latent tuberculosis (TB) contributes to the global success of the pathogen, Mycobacterium tuberculosis (Mtb). We sought to test whether aerosol infection of rabbits with Mtb H37Rv could model paucibacillary human latent TB. The lung burden of infection peaked at 5 weeks after aerosol infection followed by host containment of infection that was achieved in all rabbits. One-third of rabbits had at least one caseous granuloma with culturable bacilli at 36 weeks after infection suggesting persistent paucibacillary infection. Corticosteroid-induced immunosuppression initiated after disease containment resulted in reactivation of disease. Seventy-two percent of rabbits had culturable bacilli in the right upper lung lobe homogenates compared to none of the untreated controls. Discontinuation of dexamethasone led to predictable lymphoid recovery, with a proportion of rabbits developing multicentric large caseous granuloma. The development and severity of the immune reconstitution inflammatory syndrome (IRIS) was dependent on the antigen load at the time of immunosuppression and subsequent bacillary replication during corticosteroid-induced immunosuppression. Clinically, many aspects were similar to IRIS in severely immunosuppressed HIV-infected patients who have functional restoration of T cells in response to effective (highly active) antiretroviral therapy. This corticosteroid model is the only animal model of the IRIS. Further study of the rabbit model of TB latency, reactivation and IRIS may be important in understanding the immunopathogenesis of these poorly modeled states as well as for improved diagnostics for specific stages of disease.

Abstract
IL-17 is a cytokine that induces neutrophil-mediated inflammation, but its role in protective immunity against intracellular bacterial infection remains unclear. In the present study, we demonstrate that IL-17 is an important cytokine not only in the early neutrophil-mediated inflammatory response, but also in T cell-mediated IFN-gamma production and granuloma formation in response to pulmonary infection by Mycobacterium bovis bacille Calmette-Guérin (BCG). IL-17 expression in the BCG-infected lung was detected from the first day after infection and the expression depended on IL-23. Our observations indicated that gammadelta T cells are a primary source of IL-17. Lung-infiltrating T cells of IL-17-deficient mice produced less IFN-gamma in comparison to those from wild-type mice 4 wk after BCG infection. Impaired granuloma formation was also observed in the infected lungs of IL-17-deficient mice, which is consistent with the decreased delayed-type hypersensitivity response of the infected mice against mycobacterial Ag. These data suggest that IL-17 is an important cytokine in the induction of optimal Th1 response and protective immunity against mycobacterial infection.

Abstract
We report the case of a 55-year-old male with a large left adrenal mass that conformed to the normal shape of the adrenal gland. Percutaneous biopsy revealed tuberculosis and, following anti-tuberculosis therapy, there was a >75% decrease in the size of the mass. In large tumefactions of the adrenal glands in which a normal adrenal contour is maintained, a percutaneous biopsy may obviate the need for major intervention.

Abstract
A 37-year-old woman presenting with galactorrhea and menstrual irregularity due to an intrasellar lesion of the pituitary gland underwent transsphenoidal surgery for histopathological diagnosis and removal of the lesion. Histological findings were consistent with a tuberculoma. The post-operative course was satisfactory with resolution of galactorrhea and improved ovulatory cycle. The patient was successfully treated with a combination of surgical resection and anti-tuberculous therapy for one year, which resulted in hormonal and tuberculosis control. This patient appears unique regarding the location of the lesion and the dramatic response to surgical treatment. Although differential diagnosis of inflammatory pathologies of the intrasellar region presents difficulties, this patient demonstrates that tuberculoma should be considered.

Abstract
PURPOSE To estimate precontrast tissue parameter (T(10)) using fast spin echo (FSE) and to quantify physiological and hemodynamic parameters with leakage correction using T(1)-weighted dynamic contrast-enhanced (DCE) perfusion imaging. MATERIALS AND METHODS Voxel-wise T(10) computation was performed followed by the analysis of T(1)-weighted DCE perfusion data for the conversion of signal intensity time curve to concentration time curve, estimation of hemodynamic and physiological perfusion indices, and a method for leakage correction. Validations of accuracy of the computations have also been carried out. RESULTS The computed T(10) and hemodynamic perfusion indices in normal white and gray matter were in good agreement with the literature values. Physiological perfusion indices in these regions were found negligible, validating computations. Cerebral blood volume (CBV) values change negligibly over the length of concentration time curve in white matter, gray matter, and lesion (CBV(corrected)), while CBV(uncorrected) (lesion) shows linear increase over time. CONCLUSION T(1)-weighted DCE perfusion data along with FSE-based T(1) estimation can be used for an accurate estimation of hemodynamic and physiological perfusion indices.

Abstract
The ability of Mycobacterium tuberculosis to persist in a dormant state is a hallmark of tuberculosis. An insight into the expression of mycobacterial proteins will contribute to our understanding of bacterial physiology in vivo. To this end, the expression of FtsZ, Acr and DevR was assessed in the lung granulomas of guinea pigs infected with M. tuberculosis. Antigen immunostaining was then compared with the detection of acid-fast bacilli (AFB) and mycobacterial DNA. Surprisingly, immunostaining for all three antigens was observed throughout the course of infection; maximum expression of all antigens was noted at 20 weeks of infection. The intensity of immunostaining correlated well with the presence of intact bacteria, suggesting that mycobacterial antigens in the extracellular fraction have a short half-life; in contrast to protein, extracellular bacterial DNA was found to be more stable. Immunostaining for bacterial division and dormancy markers could not clearly distinguish between replicating and non-replicating organisms during the course of infection. The detection of Acr and DevR from 4 weeks onwards indicates that the dormancy proteins are expressed from early on in infection. Both antigen staining and DNA detection from intact bacilli were useful for detecting intact mycobacteria in the absence of AFB.

Abstract
Tuberculosis is a chronic systemic granulomatous disease which rarely affects the oral cavity. Oral lesions can be either primary or secondary to systemic tuberculosis, the former being rare. This is a never-before reported case of primary tuberculosis presenting as a localized diffuse gingival enlargement in an 11-year-old Indian female patient. The diagnosis was reached through identification of positive histopathological features, Tuberculin test results, presence of anti-tubercular antibodies confirmed by a polymerase chain reaction. In view of the recent increase in the incidence of tuberculosis and the prevalence of the same, it is reasonable to include tuberculosis in the differential diagnosis of gingival enlargements. This is essential to avoid any serious complications for both the clinician and patient due to a delay in the diagnosis of such a rare but plausible oral condition.

Abstract
OBJECTIVE For staging, follow-up and even screening (www.screening.info) an "all-in-one" imaging examination is desirable. In the concept of whole body MRI, lung imaging prevails as the weakest link. The purpose of our study was to determine the optimal MRI sequences for the detection of malignant lung nodules. PATIENTS AND METHODS On the basis of 6 lung cancer, 46 metastases and one tuberculoma in 13 patients eight MRI sequences--HASTE, IR-HASTE, fat saturated TrueFISP, STIR, VIBEipat = 2, and contrast-enhanced (CE) VIBE (with ipat = 2, 0, 4) performed with parallel imaging and 12 matrix coil elements--were compared in terms of contrast-to-noise ratio (CNR) and quality in the visualization of the lung nodules using multidetector CT as standard of reference. The parameters of the sequences were pragmatically selected to minimize the imaging time to allow for imaging the entire lung within one breathold interval. RESULTS The STIR sequence was found to be the best for detecting malignant lung nodules (p<0.01) followed by the FS TrueFISP, CE VIBE subsetipat = 0, CE VIBE subsetipat = 2, IR-HASTE, HASTE, CE VIBE subsetipat = 4, and VIBE. The STIR sequence visualized malignant nodules down to 2 mm in size and did not display the 19 mm tuberculoma. CONCLUSION The STIR sequence should be included in future studies investigating if MRI can compete with CT in the early identification (detection and classification) of malignant lung nodules.

Abstract
Tuberculoma of the liver is rare in an immunocompetent individual. We report a 26-year-old man with upper abdominal pain, abnormal liver function, and raised inflammatory markers. Abdominal computed tomography (CT) scan revealed a mixed attenuation lesion measuring 6 x 5 cm occupying most of the left lobe of the liver. Subsequent histology and culture confirmed tuberculous abscess. Following antituberculous therapy, repeat CT scan revealed complete resolution of the initial findings. This case illustrates the diagnostic difficulties of hepatic tuberculosis (TB) and the importance of considering TB in patients with hepatic lesions.

Abstract
Orbital tuberculoma is not uncommon in the developing countries, but intracranial extension of orbital tuberculoma is extremely rare. Our case, a 14-year-old girl, presented with proptosis and progressive painless diminution of vision eventually leading to loss of vision. MRI showed a mass with peripheral enhancement of contrast, separate from the optic nerve and extending into the cranium through the optic foramen. Early decompression and chemotherapy resulted in marked visual recovery. Histopathology of the excised lesion confirmed tuberculosis. The case is reported to highlight both the rare presentation as well as remarkable visual recovery in a patient with orbital tuberculosis.

Abstract
PURPOSES Ten to fifteen percent of granulomatous hepatitis are idiopathic. If symptoms like prolonged fever are present, empirical treatment is discussed. The goal of this study is to describe the empirical treatment proposed in this situation by French specialists of internal medicine. METHODS We conducted a practice investigation among the French national society of internal medicine (SNFMI), using an anonymous questionnaire that related a case of idiopathic granulomatous hepatitis. This questionnaire was proposed to all French internists present at the SNFMI congress in June and December 2004. French specialists of internal medicine had to answer if they would prescribe an empirical treatment and if so, to specify this treatment. RESULTS Thirty-six French specialists of internal medicine answered to the questionnaire. In the proposed situation, 89% of them initiate an empirical treatment. In 18/36 cases (50%), a first-line anti-tuberculosis empirical treatment is proposed (quadritherapy in 11 cases). In 7 cases (19%), an empirical treatment with prednisone, 0.4 mg/kg/d (N=1) and 1 mg/kg/d (N=6), would be prescribed. Seven internists (19%) would prescribe an empirical treatment with cyclins at the dose of 100 to 400 mg/d. Median duration of the empirical treatment would be 28 days (range: 8-252d). The evaluation parameters mentionned are: fever (69%), weight (59%), seric level of C-reactive protein (59%), and liver biology (53%). In case of failure of first-line empirical treatments, 69% of all questionned internists prescribe a second-line treatments: prednisone at the dose of 0.4 to 2 mg/kg/d (72%), anti-tuberculosis treatments (16%), cyclins 200 mg/d (12%), with a median duration of 28 days. Seven internists (19%) propose to combine two empirical treatments. DISCUSSION Faced with a problem of idiopathic granulomatous hepatitis, French internists questionned propose four therapeutics options: no treatment, anti-tuberculosis treatment, cyclins or steroids treatment. First-line anti-tuberculosis treatment is a coherent proposition regarding to the high prevalence of tuberculosis. There are only few data available concerning empirical treatment with steroids or cyclins. Specific proposition of such empirical treatments should be defined. CONCLUSIONS The management of idiopathic granulomatous hepatitis is difficult. Our study shows that therapeutics practices of French internists are heterogenous. The main proposition consists in a first-line anti-tuberculosis empirical treatment, that has to be evaluated after four weeks, and switched with steroids (prednisone, 1 mg/Kg/d) in case of failure. This study is not an expert proposition but contributes to suggest clinical practice guidelines for a rare, complex, heterogenous, and typically internist situation.

Abstract
BACKGROUND Intramedullary spinal tuberculoma is a rare form of central nervous system tuberculosis. This article describes the successful management of intramedullary spinal tuberculoma in 3 patients who received treatment between 2000 and 2003. CASE DESCRIPTION The character of 3 cases was analyzed retrospectively, including clinical manifestation and magnetic resonance imaging findings. All masses were excised totally under microscope. Histopathologic examination revealed tuberculoma. Postoperatively, all patients received a 6 to 9 month course of ATT. The outcome was favorable. CONCLUSIONS The intramedullary spinal tuberculoma must be considered in the differential diagnosis of the spinal cord compression in patients with a history of tuberculosis. When confronted with a progressing neurologic deficit and poor response to ATT, surgical intervention should be considered. The optimal treatment is a combination of microsurgical resection and ATT.

Abstract
OBJECT The use of a supraorbital craniotomy as a minimally invasive neurosurgical technique to treat pathology located in the anterior cranial fossa and parasellar region is reported. MATERIALS AND METHODS 25 patients were operated upon using the supraorbital keyhole technique to expose various lesions located in the anterior skull base. Included were benign and malignant tumors, AVM, tuberculoma and trauma. DISCUSSION AND CONCLUSION Utilizing small eyebrow incisions, a small supraorbital ("keyhole") craniotomy, and microneurosurgical and/or endoscopically assisted access, allowed us to gain excellent optimal and safe exposure to a number of different pathologies of the anterior base and parasellar regions. The lesions were resected under complete control and with full preservation of surrounding neurovascular structures.

Abstract
BACKGROUND & OBJECTIVE Survivin, an anti-apoptosis gene, expresses in most tumors, and takes part in tumor angiogenesis. This study was to investigate microvessel density (MVD) and expressions of Survivin and vascular endothelial growth factor (VEGF) in non-small cell lung cancer (NSCLC), and explore their correlations to clinicopathologic features of NSCLC. METHODS MVD and expressions of Survivin and VEGF in 96 specimens of NSCLC tissues, 31 specimens of tumor adjacent tissues, and 20 specimens of benign lesions were detected by SP immunohistochemistry; their interrelations and correlations to clinicopathologic features of NSCLC were analyzed. RESULTS Positive rate of Survivin was significantly higher in NSCLC than in adjacent tissues and benign lesions (69.8% vs. 16.1% and 0, P<0.05); its expression was related with differentiation and TNM stage of NSCLC. Positive rate of VEGF was significantly higher in NSCLC than in adjacent tissues and benign lesions (72.9% vs. 45.2% and 25.0%, P<0.05); its expression was related with lymph node metastasis and TNM stage of NSCLC. MVD was significantly higher in NSCLC than in adjacent tissues and benign lesions (24.44+/-7.79 vs. 19.37+/-5.26 and 11.83+/-6.25, P<0.05), and was related with lymph node metastasis and TNM stage of NSCLC. Survivin expression was positively correlated with VEGF expression and MVD. CONCLUSION Survivin is overexpressed in NSCLC, which relates with differentiation and TNM stage of NSCLC and takes part in angiogenesis.

Abstract
BACKGROUND The liver is often involved secondarily by sytemic/extrahepatic vascular, metabolic, infectious, granulomatous, and malignant processes. CASE REPORT A 57-year old woman was admitted because of fatigue, malaise, night sweating and right upper abdominal quadrant pain. Physical findings revealed pale skin and mucosae, and hepatomegaly. Laboratory data showed normocytic, normochromic anemia and marked inflammatory syndrome. Real-time ultrasonography revealed one hypo-echogenic nodule, 25 mm in size, in the segment II of the liver, and three hypoechogenic nodules, 11-25 mm in diameter, in segments III and IV. Enlarged lymph nodes, 20-50 mm, were observed in the region of the pancreatic head. Histo-pathological examination of the liver and peritoneum biopsies evidenced granulomas with caseous necrosis and multinuclear Langhans' giant cells, indicating hepatic and peritoneal tuberculosis. The tuberculostatic chemotherapy (isoniazid 300 mg/24h; rifampycin 600 mg/24h and pyrazinamid 2000 mg/24h) was applied for 12 months. The patient responded well to the treatment, followed-up for 6-12 months. CONCLUSION In the differential diagnosis of focal liver lesions, pseudotumoral hepatic tuberculomas must be considered.

Abstract
Recent technologic advances have significantly enhanced the role of imaging in the detection, characterization, and management of infectious diseases involving the liver. In addition, imaging-guided percutaneous drainage has greatly improved the clinical treatment of patients with focal liver abscess. Infectious liver diseases can be accurately evaluated with ultrasonography (US), computed tomography (CT), and magnetic resonance (MR) imaging. Characteristic changes in US echogenicity, CT attenuation, or MR imaging signal intensity and typical enhancement patterns can contribute to the diagnosis of specific infectious diseases, including abscesses, parasitic diseases, fungal diseases, granulomatous diseases, viral hepatitis, and other less common infections. CT is particularly helpful in revealing the presence of calcifications and gas and in detailing the enhancement pattern. The multiplanar capability of MR imaging and its sensitivity to small differences in tissue composition increase its specificity for certain hepatic infections, including hydatid cyst and candidiasis. Radiologic findings may be sufficient to obviate aspiration or histologic examination, although in most instances they are less specific. Nevertheless, imaging findings taken together with appropriate clinical information may provide the most likely diagnosis, even if biopsy is sometimes required for confirmation.

Abstract
To enhance the informative value and validity of X-ray study in detecting destructive changes in infiltrates, tuberculomas, and blocked caverns, the authors treated their computed tomographic scans by linear spatial filtration and identification of equidensite fields. In this case, after treatment of an image, the phase of decay in the presence of filtrates was 14.2% and increased up to 36.1%. Cavernous processes are detectable when the scans of blocked caverns that are frequently taken as infiltrates are treated.
