ABSTRACT
OBJECTIVE:
To describe the clinical presentation, radiological findings, management details, and outcome in nine cases of tuberculous brain abscess (TBA). MATERIALS ANDMETHODS:
Nine patients (5 females, 4 males) harboring a TBA, as defined by the Whitener's criteria, were managed over a span of one and a half decade by the authors. All, except one patient, underwent contrast-enhanced magnetic resonance imaging scans, followed by surgical excision of the abscesses due to the failure of complete resolution of the lesion after its drainage using a burr-hole.RESULTS:
The infra-tentorial location (n = 4) in TBAs was as common as the supra-tentorial location (n = 4). All large TBAs (more than 3 cm in diameter) failed to resolve after tapping of the purulent material and required surgical excision for a favorable long-term outcome. Two patients expired, while seven patients survived with Karnofsky Performance scale of 90 for 3, 80 for 3, and 70 for 1 patient. The follow-up ranged from 2 to 12 years (mean = 5.7 years).CONCLUSION:
TBAs should be considered in the list of differential diagnoses for pyogenic abscesses, especially in developing countries, as it is difficult to differentiate between them on the basis of clinical or radiological findings. Hence, all pus samples should be sent for Ziehl-Neelsen staining and culture for Mycobacterium tuberculosis. Surgically excised and pathologically evaluated specimens remain the gold-standard for diagnosing TBAs. Larger abscesses warrant surgical excision, while concomitantly associated smaller lesions tend to resolve with prolonged antituberculous therapy.
