Abstract

SETTING: A referral hospital in South Africa.OBJECTIVE: To describe the clinical presentation, serial brain imaging findings during treatment and outcome of patients with intracranial tuberculoma in a high human immunodeficiency virus (HIV) prevalence setting.DESIGN: This was a retrospective observational study conducted over a 12.5-year period. Records of adults (age ≥18 years) who presented with neurological TB were screened. We included patients with tuberculoma in whom sequential brain imaging was performed.RESULTS: Of 66 patients enrolled, HIV status was known in 61; 47 (71%) were HIV-infected and 14 (21%) were non-HIV-infected. Clinical and imaging findings and outcomes were similar between these groups. Persistent tuberculoma was present at 18 months follow-up in 20/41 (49%) patients who underwent repeat imaging at that timepoint; those with persistent tuberculoma were more likely to have persisting neurological abnormalities (85% vs. 52%; P = 0.043). Larger tuberculoma size at presentation (≥3 cm) was the only factor significantly associated with tuberculoma persistence (multivariable logistic regression, OR 19.9, 95%CI 1.27-309.68; P = 0.033).CONCLUSION: Tuberculoma is a severely disabling TB manifestation regardless of HIV coinfection, with half of patients showing radiologically persistent lesions at 18 months follow-up. Large size of tuberculoma at presentation heralds lower chance of its resolution within 18 months.
