Intracranial tuberculomas: review of MRI findings and clinical features.

Aim: To present a comprehensive analysis of the clinical features and magnetic resonance imaging (MRI) findings of intracranial tuberculomas in Indonesia.

Materials And Methods: This was a retrospective analysis of brain MRI from 58 patients (29 women), mean age ± SD = 39 ± 2 years, diagnosed with intracranial tuberculomas. Clinical data, including symptoms, cerebrospinal fluid examination results, and MRI were also analysed. The diagnosis of intracranial tuberculoma was confirmed based on observed MRI changes following anti-tuberculosis therapy.

Results: A total of 603 tuberculomas were fully detected via MRI in all patients. Among these lesions, 507 (84%) were located in the cerebrum, 61 (10%) in the cerebellum, 19 (3%) in the basal ganglia, 12 (2%) in the brain stem, and four (1%) in the thalamus. The MRI signals were classified into two groups: tuberculomas with caseating granulomas and tuberculomas with non-caseating granulomas. Among the patients, 29 had concomitant meningitis, seven had hydrocephalus, and four had cerebral infarction. Evidence of pulmonary tuberculosis was found in 16 patients, with one patient having coexisting thoracic vertebral tuberculosis.

Conclusion: The present study confirmed the significance of MRI as a valuable tool in the diagnosis of intracranial tuberculomas and the detection of associated abnormalities. The combination of MRI findings with clinical features can enhance the overall diagnostic accuracy for intracranial tuberculomas.
