Tuberculomas of the brain in children constitute 5% to 8% of intracranial space-occupying lesions in developing countries. These have in the past been treated with antituberculous drugs and with excision of large masses when the intracranial tension was high. Computed tomography (CT) has modified this approach. CT has resulted in earlier diagnosis and has been of help in monitoring the results of medical treatment of tuberculomas in children. With such monitoring there has been less need for surgical excision. At the same time, it has been realised that some caution is required towards our dependence on CT, as the image morphology of a tuberculoma could simulate other lesions like a glioma, and surgical excision needs to be carried out when in doubt or when there is no appreciable improvement in CT appearances with medical treatment.

Tuberculomas of the brain continue to be prevalent in all the developing countries of Asia, Africa, South American and Europe and seem to be making a comeback in the richer nations of the West. They pose a challenge to the neurosurgeon, in spite of the advances that have been made in the diagnosis of these lesions and in the available therapeutic regimes. During the last decade, computed tomographic (CT) scan has facilitated early diagnosis of tuberculomas at a stage when the lesions are small and antituberculous therapy (ATT) has been found beneficial in the majority of patients. Those lesions that do not respond need change in the ATT regimen and addition of steroids. Some lesions tend to disappear by themselves after a few weeks and probably are not tuberculous in nature. Some continue to grow in spite of ATT, probably due to drug resistance and require surgery, and some turn out to be gliomas. As it is not possible to differentiate between glioma or tuberculoma from CT morphology alone, and as stereotactic biopsy can be expensive, it is worth a trial with ATT, reserving surgery only to those which continue to grow inspite of ATT.

An analysis of 386 cases of Intracranial Space Occupying Lesions (SOL) including neoplastic and inflammatory masses diagnosed and treated at Jinnah Postgraduate Medical Centre, Karachi over a period of 2 years is presented. C.T. Scan and MRI were used for the diagnosis of midline, multiple and very small lesions. S.O.L. were more common in males in the age group 11-20 years. Gliomas comprised 32.1% of the total cases followed by meningiomas 13.7%, abscesses 13.2% and pituitary tumours 13.2%. Tuberculomas constituted 5.5% and therefore, should always be considered in the differential diagnosis.

Tuberculomas (TB) can mimic brain tumors and abscesses. We performed prospective magnetization transfer ratio (MTR) analysis on 60 patients with 52 intracranial TB, 13 pyogenic abscesses and 65 tumors to determine the efficacy of magnetization transfer (MT) imaging in the differential diagnosis of brain tumors and infection. The nonenhancing cores of TB had significantly higher (P=.026) MTR (0.14+/-0.29) than necrotic components of high-grade gliomas (-0.19+/-0.22). The MTR of cores of TB were also higher than those of the cystic areas of low-grade gliomas (-0.53+/-0.32), benign (-0.09+/-0.21) and malignant (-0.07+/-0.25) tumors, and abscesses (-0.03+/-0.13), but the differences were not significant because of the small number of tumors and abscesses. There was also no significant difference between the MTR of abscesses, malignant and benign tumors. Using the criteria of MTR of necrotic center > 0.14 (mean MTR of TB) for diagnosing TB, MTR <-0.03 (mean MTR of abscesses) for diagnosing tumors and MTR between these values for diagnosing abscesses, MTI had diagnostic sensitivity of 68.42%, specificity of 80.49%, and accuracy of 76.67%. The improved diagnostic accuracy of MRI with the addition of MTR analysis from 86.67% to 91.67% and from 85.71% to 87.50% for both radiologists respectively was not significant. MTR analysis helped us to differentiate solitary TB or abscess from low-grade glioma in five patients and to diagnose multiple TB, abscesses, and metastases in four.
