Analysis of 93 Brain Abscess Cases to Review the Effect of Intervention to Determine the Feasibility of the Management Protocol: A Tertiary Care Perspective

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

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.

Silent persistent left superior vena cava right-to-left shunt as a unique cause of recurrent brain abscesses

We present a novel case of recurrent brain abscesses found to be the result of a silent congenital right-to-left extra-cardiac shunt, a persistent left superior vena cava (PLSVC) draining into the left atrium. The patient’s brain abscess was evacuated surgically, treated with antibiotics, and his shunt was subsequently repaired. The case suggests that attention should be paid to evaluation for shunt physiology allowing for bypass of the pulmonary circulation in those with recurrent brain abscesses.

[Successful microsurgical resection of a large brainstem abscess: case report and literature review]

OBJECTIVE

To present a patient with brainstem abscess treated by microsurgical resection.

CASE PRESENTATION

A 53-years-old female patient admitted to the neurosurgical department in a severe condition with symptoms of intracranial hypertension, hyperthermia, general infectious signs and laboratory manifestations of infectious process. Contrast-enhanced MRI revealed a large brainstem lesion (abscess). Retrosigmoid craniotomy with total microsurgical resection of the abscess was performed. External ventricular drainage was incerted on the second postoperative day due to progressive hydrocephalus with clinical deterioration, it was removed in 8 days. Slow positive dynamics was observed in postoperative period. The patient was discharged in 2 weeks after surgery.

CONCLUSION

There are no established algorithm for the treatment of brainstem abscesses. Therapeutic approach is advisable for small abscesses. There are 2 neurosurgical options for this lesion: stereotactic drainage and microsurgical resection with or without external ventricular drainage. Treatment strategy depends on location and size of abscess, as well as clinical state of the patient.
