Hi the mri
report of your brain shows leison which are commonly due to infection by cysticercosis
in indian population. Based of the appearance of lesion in mri sometimes its difficult to confirm the cause. If the lesion is large with more edema then tuberculosis is common. In your case the second mri shows resolution of lesion with edema seen. Its better to continue the anti TB treatment for few more months as the lesion is responding to treatment. A high quality mri after few weeks may show whether the edema has gone or any scar if lesion is seen. Wish u early recovery.
