How To Interpret Mri Test Result?

My 5 years old son (I had him through normal delivery and his development milestones are normal) started to complain about abdominal pain around 2 years ago. The episodes of the groaning and pain last usually few minutes and then he feels better or sleep and it can occur up to 3 times a week. We’ve seen doctors and nothing could be traced to be the cause. Last year the child behave a bit violent during the pain. An EEG was done April 2013 and a temporal lobe epilepsy was suspected and a follow up CT scan showed an appearance of a mass at the temporal lobe. We saw the neuro pediatrician in June 2013 and he was placed on tegretol twice daily had relief for about 3 months then it started again. The doctors have been varying the doses of the tegretol but the symptoms persist. We saw the neuro 2 weeks ago and he recommended an MRI. I just saw the results. It reads something like lesion involving left prepontine, left cerebello – pontine angle cistern, left peri – mesencephalic cistern, left peri – mesencephalic cistern, left …thalamus and mesial temporal lobe appearing hyperintense on T2 and isointence on T1 and is showing mild restricted diffusion. Few area of necrosis is seen within lesion. The report suggested infective (granulomatous) etiology? Koch’s (Tuberculoma). I saw the neuro with the result we are given another appointment. I’m scared. Is my son case curable? What’s his chances of survival? I live in part of Africa where advance medical services is not readily available.
