Thank you for posting your query.
The initial treatment for tuberculous meningitis
was started on empirical grounds (without confirming the diagnosis). If the current MRI
had not shown any new findings, then, the doctor would have continued the TB treatment for at least another 7 months.
Since, there are tuberculomas, it is possible that we are dealing with multi-drug resistant TB or some other infection/disease, so, I also agree that biopsy
of the brain lesion is the best option at this point.
