Tuberculosis (TB) of the central nervous system (CNS) is still prevalent in many developing countries. Tuberculoma is always considered in the differential diagnosis of enhancing intra-axial lesions of the brain. Brain tuberculomas can present in many different clinical and radiological patterns, disseminated or miliary brain tuberculomas are very rare. We describe the case of a 25-year-old immunocompetent female with miliary brain tuberculomas. She presented with a history of progressive headache and unsteady gait. Serial Magnetic resonance imaging (MRI) studies revealed growing, multiple small enhancing lesions in the brain, most lesions measured approximately 2mm in diameter, in both the supratentorial and infratentorial compartments. Her investigation failed to reveal any evidence of TB outside the CNS. Open biopsy revealed multiple caseating granulomas and mycobacterin tuberculosis was cultured. She improved clinically and radiologically after starting anti-tuberculous pharmacotherapy. The clinical course, radiological images and pathological studies of this patient are presented. In conclusion miliary brain tuberculomas are rare and unique clinical and radiological entity. It may affect immunocompetent individuals with no other signs of other systemic involvement.

Tuberculosis usually involves the brain through haematogenous spread. The mass lesion caused by tuberculosis in the brain is called tuberculoma, which is a conglomerate of tubercles. Tuberculomas may also be found in the spinal cord. Because of their slow growth they often become calcified. The study was conducted at the King Fahad Hospital, Hofuf, Al Hassia, Saudi Arabia between 1992 and 1998. It was a prospective study of all patients which had intracrainal mass lesions which showed typical ring-enhancement on brain CT scan with contrast. Twenty patients satisfied inclusion into the study. Of the 20 patients studied, 19 (95%) were males and 1 (5%) was a female. The ages ranged between 22 and 50 years. Eighteen (90%) of the patients were immigrant labourers from Asia and 2 (10%) were Saudi nationals, a male aged 50 years and a female aged 22 years. Fifteen (83.5%) were from India, 2 (11.1%) from Bangladesh, and 1 (5.6%) from Sri Lanka. The presenting feature in 60% of cases was focal seizure with secondary generalisation. 20% had primary generalized seizures, and 30% presented with headache, 25% with weakness of the limbs, 15% with fever and 10% each with vomitting and blurred vision, respectively. In 65% of cases, there was noneurological deficit but 35% had pyramidal weakness in the limbs. In 55% of cases the Tuberculomas were located in the left cerebral hemisphere. 30% in the right cerebral hemisphere and in 15%, the lesions were in both hemisphere. When a male Asian immigrant labourer aged between 20 and 40 years presents with seizures with or without headache, he should have a brain CT scan with contrast to exclude intracranial Tuberculoma. A short course of anti-tuberculous therapy may be tried where there is doubt, irrespective of normal erythrocyte sedimentation rate (ESR). We suggest that when the presenting symptom is primary generalized tonic clonic seizure, the intracranial Tuberculoma is located in the frontal lobe: a high erythrocyte sedimentation rate (ESR) may indicate multiple Tuberculomas.

Tuberculosis can involve any organ system of the body. Although rare tuberculosis of nervous system (NS) is not uncommon in our country. In the nervous system tubercle bacilli can cause tuberculous meningitis, abscess , tuberculoma in brain & spinal cord. Untreated Central Nervous System (CNS) tuberculosis is devastating. Early diagnosis & prompt treatment of NS is essential to avoid morbidity & mortality. Tubercle bacilli causes chronic caseating granulomatous lesion. Tubercular meningitis presents with fever, headache, neck stiffness & cranial nerve palsy. Tuberculoma may present with headache, seizure and focal deficit. In the spinal cord tuberculoma or tubercular abscess may result in para paresis or quadri-paresis. For diagnosis of nervous system tuberculosis CSF analysis and neuroimaging are important. CSF cell count, Gram staining, Culture and Polymerase Chain Reaction (PCR) are helpful for diagnosis. Imaging helps in the diagnosis of tuberculoma and tubercular abscess. Computed tomography (CT) guided Fine Needle Aspiration for Cytology (FNAC) helps to establish the histopathological diagnosis. Use of combination antitubercular drugs for long period (12-18 months) is necessary to treat nervous system tuberculosis.

We report the case of a 10-year-old child from Reunion Island who was hospitalized because of headaches and partial convulsive fits. The brain MRI showed several conglomerated right frontal lesions suggestive of a tumor process. This girl, vaccinated with BCG, had familial risk factors for tuberculosis and a 20-mm tuberculin intradermo-reaction. Given the palpation of an abdominal mass, a thoracoabdominal scan was done, which revealed the presence of mesenteric adenopathies. Their biopsy confirmed the diagnosis of tuberculosis without having to perform neurosurgery. A 2-month quadritherapy and a 10-month dual therapy against tuberculosis led to the disappearance of brain damage and mesenteric adenopathies, with focal epilepsy the only sequela. The tuberculosis incidence in Reunion Island (8/100,000) is comparable with the French average, but the island is surrounded by high-endemic countries. Tuberculomas were responsible for one-third of expanding intracranial lesions in Europe in 1933, and their incidence remains high in developing countries. Even though extrapulmonary or disseminated tuberculosis has become rare in children in industrialized countries, this diagnosis must be kept in mind, in spite of vaccination. In accordance with international guidelines, this case report shows the importance of a systematic extensive check-up (cervical, thoracic and abdominopelvic) when brain tuberculosis is suspected in order to find more accessible tuberculosis lesions and to avoid the side effects of a brain biopsy.

Brain tuberculosis is still prevalent in many developing countries, especially Asian countries. Tuberculomas should always be considered in the differential diagnosis of enhancing intra-axial lesions of the brain. Brain tuberculomas can present in many different clinical and radiological patterns clinically like headache, fits, cranial nerve palsies and very rarely as brain tuberculomas. We describe the case of a 48 years old male patient presenting with persistent headache and fits, referred for workup of brain metastasis or primary brain neoplasm. On further imaging, it turned out to be multiple tuberculomas of brain which resolved on anti-tuberculous treatment along with symptoms relief.

Tuberculomas are small tumor-like lumps that can be seen, usually in large numbers, in central nervous system involvement of tuberculosis. Giant tuberculomas that are big enough to cause symptoms of compression are also encountered, though rarely. When they are really large, tuberculomas may result in increased intracranial compression, neurologic deficits, or epileptic attacks. Giant tuberculomas may be confused with brain tumors on cranial magnetic resonance imaging. Cranial magnetic resonance imaging and histopathology examinations are used for diagnosis. Although magnetic resonance imaging is useful for diagnosing tuberculoma, histopathology examination is the gold standard for a final diagnosis. This paper presents a case involving a 66-year-old patient who complained of headache, imbalance and dizziness, and underwent an operation in the neurosurgery clinic with a pre-diagnosis of brain tumor, and was then diagnosed with intracranial giant tuberculoma.

BACKGROUND Tuberculoma and neurocysticercosis (NCC) often show similar clinical and neuroimaging features. Differential diagnosis of these 2 diseases is imperative, as tuberculoma is an active infection that requires immediate anti-tubercular therapy (ATT). CASE REPORT We present the case of a 17-year-old Indian girl with fever, severe headache, and right 6th cranial nerve palsy. Brain magnetic resonance imaging (MRI) showed multiple tiny ring-enhancing lesions in bilateral cerebral parenchyma with mild perilesional edema, which were initially thought to be NCC, but subsequently were diagnosed as brain tuberculomas. Based on clinical findings, mildly increased choline/creatine ratio (1.35) with slight prominent lipid lactate peak and absence of alanine, succinate peak by magnetic resonance spectroscopy (MRS), and the detection of Mycobacterium tuberculosis (Mtb)-specific early-secreted antigenic target-6 (ESAT-6, Rv3875) protein from the cerebrospinal fluid (CSF) by indirect ELISA, as well as indirect immuno-PCR (I-PCR) assay, diagnosis of brain tuberculomas associated with tuberculous meningitis (TBM) was confirmed, which was followed by ATT. The patient responded well and the symptoms resolved. CONCLUSIONS In this case, multiple ring-enhancing lesions of the brain by MRI were diagnosed as tuberculomas associated with TBM by MRS and indirect ELISA/I-PCR method, thus resolving the diagnostic dilemma.

Tuberculoma is one of the manifestations of tuberculosis infection in the central nervous system. Even though its prevalence is only 1%, the mortality rate is high. Clinical presentation in immunocompromised patients with tuberculoma maybe different, thus making the diagnosis difficult. We present the case of a 13-year-old girl who was admitted for routine intravenous administration of cyclophosphamide and steroid therapy for nephritis due to systemic lupus erythematosus. She experienced severe headache and focal seizure on the second day of hospitalization. Neurology examination did not show any abnormalities. The Xpert MTB/RIF from the cerebrospinal fluid and sputum yielded negative results. Computed tomography scan and magnetic resonance imaging showed tuberculoma with caseous necrosisaround the fibrous capsule in the right occipital lobe of the brain. Electroencephalography showed no abnormalities. Clinical improvement was seen after 3weeks of treatment; however, antituberculosis drug-induced hepatotoxicity occurred.

Isolated sellar tuberculoma is a very rare condition and usually presents with headache and decreased vision. It can present with panhypopituitarism with 3rd nerve palsy. Tuberculoma mimics pituitary adenoma clinically as well as radiologically and requires endoscopic transsphenoidal surgery and histopathological examination for the final diagnosis. We present a rare case of a 40-year-old female presented with headache, decreased vision, and unilateral 3rd nerve palsy with panhypopituitarism.
