It important to know if for the first time she has high BP
or already taking some treatment for High BP,
She had a seizure
because of brain lesion which she has, so she has to take some anticonvulsant treatment also which I am sure she must have been advised to her,Keep BP also controlled.
Such ring enhancement lesion in our country are due to Tuberculoma
, some time it may not be possible to differntiate from malignant one but there are any other evidence of malignacy?
decide at presnet they have given therapeutic trial of Anti tubercular drugs which take 4 to 6 weeks to have effect but may be required to be given for > 1year.
In the mean time you can take a second opinion
Good luck to her.
