Abstract:
We retrospecively analyzed MRI findings of 14 patients with intracranial tuberculosis according to the disease process before anti-tuberculous medication. We also analyzed the correlativity between these findings and the clinical outcome after anti-tuberculous medication in 8 patients who had taken follow-up MR imaging. MR imaging was performed with either a 0.5T(1 patients) or 1.0T(13 patients) superconducting system with spinecho pulse sequences. Abnormalities on MRI were seen in 87%(12/14) of the patients. MRI findings consisted of meningeal enhancement(n=10), parenchymal tuberculoma(n=6), hydrocephalus(n=5), and infarction(n=5). Most of them were found within 3 months from symptom-onset. Parenchymal tuberculomas were found after 1 month of symptom-onset. All cases of hydrocephalus and infarction were associated with meningeal enhancement. On follow-up MRI after anti-tuberculous medication, changes of MR imaging did not correlate with clinical outocome in 4(50%) of 8 patients. Improvement of MRI findings were observed in patient treated for more than 3 weeks. In conclusion, MRI is a good modality in the diagnosis of intracranial tuberculosis, however, the MRI findings are not always correlated with clinical outcome after, anti-tuberculous medication.
