A hypointense core with a hyperintense rim is the most common signal characteristic on T2-weighted MRI in intracranial tuberculomas. We examined and contrasted the extracted sections of intracerebral tuberculoma with MRI findings. Central hypointensity of lesions was related to necrosis. T2-high ring was related to CD 68-positive macrophages and Langerhans giant cells. Interestingly small macrophages showed MIB-1-positive at most up to 10%. Among those inflammatory cells, spindle-shaped fibroblasts were mixed. There were no brain tissue in the nodule but gliotic brain tissue existed outside it.
