Figure 1: (a) First preoperative sagittal T1-weighted image showing an isointense lesion in pons with surrounding hypointensity in the midbrain and pons. (b) Sagittal T1-weighted image contrast showing ring enhancement. (c) Second preoperative sagittal T2-weighted image showing a hyperintense lesion in the pons with subcutaneous iso to hyperintense lesion in the subcutaneous region of the nape of the neck. (d) Sagittal T1-weighted image contrasts showing ring enhancement of the pontine lesion and contrast enhancement of subcutaneous lesion
