Tuberculoma of the brain is usually secondary to tuberculosis elsewhere in the body.
The probability of your infecting your partner will arise only if you have communicable tuberculosis elsewhere in the body.
The most common source of infection is from sputum, which contains the germs that cause tuberculosis.
I suggest you check whether there is any tuberculosis in your lungs. If there is none, the chance of you infecting your partner is miniscule.
If there be tuberculosis in your lungs, get your sputum examined for the germs. If there be no germs, once again, the chance of you infecting your partner is miniscule.
If there be germs, you must be careful for you may infect your partner. Continue treatment till your sputum is free from these germs for at least 3 months.
