Summary
A brain lesion mimicking a tumor in a patient with a history of tuberculosis was successfully treated with antituberculous drugs. This non-invasive treatment confirmed the diagnosis of tuberculoma and resolved the lesion.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- A 66-year-old male presented with neurological symptoms including headache, dysarthria, and diplopia.
- The patient had a history of pulmonary tuberculosis 40 years prior to admission.
Observation:
- Magnetic Resonance Imaging (MRI) revealed an isolated, enhancing nodular lesion in the pons.
- The lesion's appearance mimicked a brain tumor or other serious pathologies.
Findings:
- Antituberculous drugs were administered under the presumptive diagnosis of a tuberculoma.
- Complete resolution of the pontine lesion was observed after 9 months of treatment.
- The positive response to treatment confirmed the diagnosis of tuberculoma.
Implications:
- Empiric antituberculous drug administration can serve as a non-invasive diagnostic tool for suspected neurotuberculosis.
- This therapeutic approach offers a potential treatment strategy for tuberculomas presenting as focal brain lesions.
- Highlights the importance of considering tuberculosis reactivation in patients with relevant medical history presenting with unexplained neurological deficits.
