Surgical Management of Tuberculosis-related Cerebral Disorders: A Retrospective Single-center Study

Abstract

Background: Tuberculosis (TB) remains a significant global health concern, with extrapulmonary manifestations, including central nervous system involvement, posing substantial morbidity and mortality. While medical treatment with anti-TB drugs is the mainstay of therapy, certain TB-related cerebral complications, such as hydrocephalus, abscesses, and large symptomatic tuberculomas, may require surgical intervention. This study aimed to evaluate the outcomes of surgical management in patients with TB-related cerebral disorders. Methods: A retrospective analysis was conducted on 24 patients who underwent surgical intervention for TB-related cerebral disorders, including tuberculomas, hydrocephalus, and abscesses, at a tertiary care center between 2005 and December 2020. Demographic data, clinical presentations, radiological findings, surgical techniques, and treatment outcomes were analyzed. Results: The study cohort had a mean age of 35.8 ± 13.6 years, and the majority (62.5%) were male. Underlying immunodeficiency, primarily HIV infection, was present in 75% of the patients. The most common presenting symptoms were headache (83.3%), focal neurological deficits (75%), and altered mental status (54.2%). Radiological findings revealed 13 (54.2%) tuberculomas, 8 (33.3%) instances of hydrocephalus, and 3 (12.5%) abscesses. VP shunt inserted in 8 (33.3%) cases. Microscopic craniotomy performed in 7 (29.16%) cases. Aspiration through burr hole was done in 3 (12.5%) cases and stereotactic biopsy was performed in 6 (25%) cases. After 12 months of follow-up, favorable outcome achieved in 18 cases (75%) and the mortality occurred in 2 patients (8.3%). Surgical interventions included lesion resection (n = 10), stereotactic biopsy (n = 7), and ventriculoperitoneal (VP) shunt placement (n = 7). At 12-month follow-up, 18 (75%) patients had a favorable outcome, defined as clinical improvement or stabilization. Unfavorable outcomes were observed in 6 (25%) patients, including 2 deaths. Conclusion: Surgical management, in conjunction with appropriate anti-TB medical therapy, may be a valuable component of the comprehensive treatment approach for select patients with TB-related cerebral disorders. The favorable outcome rate observed in this study suggests that timely and tailored surgical intervention can contribute to improved patient outcomes. However, larger, prospective, multicenter studies are needed to further elucidate the role and long-term efficacy of surgical management in this patient population.
