A 57-year-old man was admitted because of headache, nausea, and fever up (38 degrees C). He showed nuchal rigidity slightly. CSF analysis showed 833 white blood cells (WBC) (80% monocyte), protein value of 68 mg/dl, glucose level of 36 mg/dl and ADA level of 11.8 IU/l. Brain pre-contrast CT indicated high density area in right parietal lobe, and it showed slightly homogeneously enhancement with contrast medium. MRI on T2 WI demonstrated hypointense lesion with bright central core in right parietal lobe. The lesion showed isointense on T1WI, and indicated homogeneous enhancement with Gd-DTPA. He was sent to our hospital after one week. With only antibiotics the symptoms were relieved and the CSF findings improved during the previous hospital. However, Mycobacterium tuberculosis (M. tuberculosis) DNA was detected in CSF by PCR amplification, and he recovered completely with anti-tuberculous treatment. This case was interesting to reveal atypical features of spontaneous recovery. Since Shankar's study using polymerase chain reaction (PCR) for detection of M. tuberculosis in cerebrospinal fluid (CSF), the PCR assay have been recognized to be a rapid method for diagnosis of tuberculous meningitis (TBM). But there are problems of PCR sensitivity when dealing with CSF samples containing small amount of M. tuberculosis DNA. Comparing direct PCR with nested PCR, we studied on the evaluation of PCR for diagnosis of TBM. In this study the nested PCR was positive in all CSF specimens from 4 patients with TBM, but we could not detect M. tuberculosis DNA by only the direct PCR. Nested PCR amplification improved the sensitivity and specificity.(ABSTRACT TRUNCATED AT 250 WORDS)

We report here a case of miliary tuberculosis with tubercular meningitis in which the polymerase chain reaction (PCR) amplification method was useful for its rapid diagnosis and follow up. A 70 year old male was hospitalized for further examination and treatment of diffuse small nodular shadows on the chest X-ray. After receiving antimicrobial therapy shadows still remained and he gradually lost visual acuity. He had no meningeal signs, and no remarkable finding on cranial CT. Cerebrospinal fluid examination showed increased cell number with predominantly lymphocytes. Cranial MRI (Gd DTPA) showed lateral ventricular ependymitis. Pulmonary tuberculosis and secondary tubercular meningitis were suspected, but we failed to detect microorganisms from the cerebrospinal fluid, gastric juice, sputum, and urine by the conventional method. However, by the polymerase chain reaction amplification method specific DNA fragments of Mycobacterium tuberculosis complex was detected from the cerebrospinal fluid, gastric juice, bronchoalveolar lavage fluid and serum. The final diagnosis of miliary tuberculosis with tubercular meningitis was established. We administered antitubercular drugs and observed the clinical course. He recovered and the polymerase chain reaction showed negative consequences in all samples. The judgement of PCR and the clinical course were compatible and parallel with the clinical course.

This community-based study analyzed 54 patients with definite or probable tuberculous meningitis (TBM) in New Mexico from 1970 through 1990. Patients ranged in age from 4 months to 86 years. The highest age-specific incidence occurred in the elderly, but 22% of patients were less than 10 years old. Native American patients were overrepresented. Patients were as likely to live in small towns as in large urban cities. Symptoms were present for a median of 13 days before admission. The majority of patients had fevers, headache, stiff neck, and mental changes, such as confusion or lethargy. No patient was admitted comatose. Focal neurologic signs were present in 33%. Laboratory testing found hyponatremia in 79%, pulmonary infiltrates on chest x-ray in 40%, ventricular dilatation on CT or MRI in 52%, and tuberculomas in 16%. PPD skin tests were positive in 64%. CSF cultures grew Mycobacterium tuberculosis in 50%, but colony counts were always lower than 10(2)/ml. As a consequence, acid-fast stains of CSF sediment were reported as positive in only 4%. Six patients were not diagnosed during the hospitalization and died of complications. Twenty-three percent of patients who were appropriately treated also died of complications during the initial hospitalization. Tuberculous meningitis continues to be an important disease in small communities, and affects all ages and ethnic and socioeconomic backgrounds.

A 26-year-old woman was admitted to our hospital because of fever of unknown origin. She had been treated with prednisolone, elcatonin and alfacalcidol under the diagnosis of systemic lupus erythematosus (SLE) and aseptic necrosis of femoral bone head. Six months ago she began to have a fever and subsequently left low back pain, for which extensive examinations were performed in other hospital but their causes remained unclear. She was referred to our hospital for further evaluation and therapy in October 1995. Bacteriological, immunological or serological examinations did not reveal the origin of fever. CT and ultrasonic examination did not show any abnormality. However, MRI, which was taken for the evaluation of aseptic necrosis of femoral bone head, showed the abscess shadow in sacroiliac joint. Open biopsy was performed and Mycobacterium tuberculosis bacilli were detected from the abscess. To our best knowledge, this is the first report of SEE with tuberculosis sacroiliac arthritis.

Systemic idiopathic fibrosis is characterized by non-suppurative inflammatory diseases of connective tissue, mainly adipose tissue. Although, in this condition, fibrosis may develop in several organs, there have been few reports of fibrosis involving the lung or pleura. We present a case of systemic idiopathic fibrosis associated with inflammatory pulmonary lesions, mimicking lung cancer with multiple pulmonary metastases. Chest CT and MRI showed a spiculated mass around the aortic arch with localized aortic wall thickening and nodules in the lungs. Abdominal CT showed a homogeneous mass around the abdominal aorta, consistent with retroperitoneal fibrosis. Transbronchial lung biopsy of the lesion in the right mid-lung field showed only a few scattered histiocytes accompanying inflammatory and fibrotic change. There was no evidence of malignancy, necrosis, angitis or mycobacterial infection. The lesions almost completely disappeared following prednisone treatment.

To provide histological diagnoses of brain diseases, CT-guided stereotactic brain biopsy (CT-SBB) has been widely used because of its less invasive technique compared with open brain biopsy (OBB). However, CT-SBB is not always diagnostic. We report a case of multiple intracranial tuberculoma whose diagnosis was not made by CT-SBB but by OBB. The patient is a 46-year-old man with insulin-dependent diabetes mellitus who had been receiving immunosuppressive agents (azathioprine, cyclosporin, and prednisolone) after renal transplantation for diabetic renal failure for 9 years. He gradually developed febrile, headache and unsteady gait. Brain MRI demonstrated multiple intracranial lesions involving left fronto-temporal and right parietal lobes, left cerebellar hemisphere, and the fourth ventricle. Although the MRI findings were consistent with those of previously reported cases of intracranial tuberculoma, other conditions, such as malignant lymphoma and toxoplasmosis, were not ruled out. Therefore, CT-SBB targeting the left temporal lobe lesion was done for definitive diagnosis, but it revealed only mild perivascular infiltration of mononuclear cells and hemorrhage. He was transferred to our clinic for further evaluation. On examination, mild truncal and limb ataxia on the left were noted in addition to the neurological findings corresponding to diabetic retinopathy and neuropathy. Despite vigorous laboratory examinations, including repeated bacterial cultures and PCR of cerebrospinal fluid, no evidence of tuberculous infection was obtained. A tentative diagnosis of multiple intracranial tuberculoma was made, and anti-tuberculous drugs (isoniazid 400 mg, ethambutol 750 mg, and pyrazinamide 1.5 g) were administered. Since his symptoms deteriorated because of ventricular dilatation resulting from the enlarged lesion in the fourth ventricle after a temporary clinical improvement, VP-shunting and OBB from the left temporal lobe lesion were done. The excised lesion was firmly encapsulated and the histological examination revealed typical pathology of tuberculoma. Ziehl-Neelsen staining and PCR for Mycobacterium tuberculosis of the biopsied specimen were also positive. Further administration of increased doses of anti-tuberculous drugs (isoniazid 600 mg, ethambutol 500 mg, pyrazinamide 2.0 g and intramuscular injection of streptomycin 0.3 g twice a week) eventually ameliorated the symptoms and shrank the lesions. In case of intracranial tuberculoma, the needle of CT-SBB may not penetrate the firm capsule of tuberculoma and only the surrounding brain tissue may be obtained as in the present case. Therefore, it is recommended to consider OBB from the beginning for definitive diagnosis of intracranial tuberculoma. Paradoxical worsening of the clinical and laboratory findings of tuberculosis in spite of appropriate anti-tuberculous therapy as seen in the present case has been described in both pulmonary and extra-pulmonary tuberculosis. The phenomenon, called transient worsening, could happen and we have to keep it in mind during the treatment of intracerebral tuberculoma.

A fifty-year-old Portuguese man presented with a six-month history of low back pain, which initially was mechanical and slowly became inflammatory. Secondarily, he complained of right atypical sciatalgia. He did not report any fever, loss of weight, cough nor personal or familial history of tuberculosis. General examination was normal. Neurologic examination showed weakness of the extensors of the right leg, with a symmetric increased reflexes of the lower extremities suggesting a pyramidal syndrome without Babinski's sign. Laboratory data were normal as well as chest radiographs. Dorsolumbar gadolinium enhanced MRI revealed an intramedullary ringlike enhancing mass at T12 level. Lumbar puncture showed 11 WBC/mm3 (95 p. 100 lymphocytes), a normal protein and glucose content. PCR and culture for Mycobacterium tuberculosis were negative. Within a few days, he developed meningoencephalitis with fever, CSF examination revealed then 360 WBC/mm3 (65 p. 100 lymphocytes and 17 p. 100 neutrophils), a protein content of 7 g/l and a glucose level of 1.7 mmol/l. The clinical picture was then suggestive of tuberculosis and a specific therapy with rifampin, izoniazid, pyrazinamid, ethambutol and steroids was started. Clinical improvement and a second CSF culture that revealed one month later Mycobacterium tuberculosis complex confirmed this diagnosis. Ten months later, the patient was asymptomatic with a normal MRI. To our knowledge, this is the first total recovery of an intramedullary tuberculoma on medical therapy alone, confirmed by MRI normalization. We reviewed also 19 recent cases of tuberculomas in the literature, intending a therapeutic attitude when discovering an intramedullary ringlike enhancing mass on MRI.

Twenty cases of tuberculous meningitis were diagnosed at the Hamad Medical Corporation between 1990 and 1995. Most of the patients (90%) were expatriates. The most common presenting features were fever, headache, neck stiffness and altered mental status. Five patients were in stage 1 disease at the time of presentation, 11 in stage 2, and four in stage 3. Examination of cerebrospinal fluid showed at least one abnormal finding in all patients, and culture grew Mycobacterium tuberculosis in 50%. A positive tuberculin skin test in 50% of patients, abnormal chest X-ray in 35%, abnormal CT scan or MRI showing tuberculoma or hydrocephalus in 55%, and positive sputum culture for M. tuberculosis in 15% helped establish the diagnosis. All the patients were treated with antituberculous drugs and steroids. Seventeen (85%) survived, three with severe neurological sequelae; three (15%) died. Poor outcome was associated with advanced stage of disease at presentation and high CSF protein. Tuberculous meningitis continues to be an important disease in Qatar, especially in expatriates, and should be considered in the differential diagnosis in any patient presenting with fever and change in sensorium.

We revised retrospectively 30 cases of Spontaneous Infectious Spondylodiskitis (SIS) in adults, diagnosed between 1986 and 1997. The mean age of the patients was 68.8 years; 56.7% were males. The identifiable causes were infectious endocarditis 13 (43.3%); tuberculosis 7 (23.3%); urinary tract infection 4 (13.3%); bacteremia with focus 2 (6.7%) and without focus 2 (6.7%). The cause was not identified in other 2 cases (6.7%). Infections were due to pyogenic bacteriae in 19 (63.3%); tuberculosis 6 (20%) and unknown 5 (16.7%). All patients had localized pain, 70% fever, 36.7% irradiated pain and 23.3% paraparesis. Fever was more frequent in patients with pyogenic etiology than in those with tuberculous SIS (p = 0.004). Blood cultures were positive in 70.4%. Percutaneous aspiration of the disc was performed in 13 patients; cultures were positive in 7. Causal germs were Streptococcus spp. 33.3%; Mycobacterium tuberculosis 20%; Staphylococcus spp. 16.6%; Escherichia coli 6.6%; Pseudomonas aeruginosa 6.6%. There was no bacteriological recovery in 5 (16.7%). Localization was lumbar in 18 (60%), dorsal in 8 (26.6%) and cervical in 4 (13.3%). X-ray of the spine was positive in 63.3% of the cases. Technetium scan in 90.5%, CT in 85.7% and MRI in 100% of cases in which it was carried out. All patients received antibiotic treatment with a median duration of 6 weeks for pyogenic SIS and one year for tuberculous SIS. Eighty three percent required immobilizing brace and 10% surgery for stabilization. Thirty six percent of patients presented complications, most of them related to the causal disease. There was a statistically significant association between mortality and diabetes.

An unusual case of tuberculosis of the lower end of the fibula in a young patient is reported. The patient presented with symptoms of pain and swelling over the outer aspect of the right ankle with full range of painless ankle movements. The plain radiographs of the ankle were normal but MRI scan showed increased signals within the lower end of the fibula on T2-weighted images. The histology of the lesion showed only a few Langhans giant cells and culture failed to grow any organism. Polymerase chain reaction analysis of the biopsy specimen, however, showed growth of Mycobacterium tuberculosis. The patient responded to antitubercular treatment with complete resolution of symptoms. Polymerase chain reaction analysis should be considered in atypical presentations with bone pain to rule out an occult infectious pathology.
