Fig 3. Case 3. A 49-year-old man with metastatic brain tumor located inside the left-sided premotor area.
A-1, Preoperative MR imaging displays heterogeneously enhancing tumor in the premotor area.
A-2, Postoperative MR imaging shows no residual tumor in the premotor area.
B, fMRI images activated by right hand clenching (B-1, B-3; orange) and left hand clenching (B-2, B-4; blue) before surgery,
C, fMRI images activated by right hand clenching (orange) and left hand clenching (blue) after surgery. The ipsilateral and contralateral M1 and the anterior temporal lobe was activated by right hand clenching before surgery, whereas the contralateral M1 was activated by right hand clenching after surgery. The area in the anterior temporal lobe activated by right hand clenching before surgery (B-1) was not activated by right hand clenching after surgery (C-1).
