case_images: Axial sections of magnetic resonance imaging scan performed 3 days before operation. T1-weighted image as hypointense (a) and T2-weighted image as hyperintense (b); mass is located in the left superior frontal gyrus

case_images: MRI revealed a 6-cm mass lesion on the T1-weighted image as hypointense and on the T2-weighted image (T2WI) as hyperintense in her left frontal SMA, which had been misdiagnosed 8 years earlier [Fig. 1].
case_images: T2-weighted scout images of intraoperative magnetic resonance imaging scan. The first intraoperative magnetic resonance imaging was performed after craniotomy (a). Extent removal of the left frontal tumor was confirmed before surgical site closure (b)

case_images: Complete removal of T2WI area was confirmed by the second iMRI; obtained 87 min into the awake phase [Fig. 2].
case_images: Axial sections of magnetic resonance imaging scan performed 11 months after awake craniotomy. T1-weighted image (a) and T2-weighted image (b) show no evidence of tumor recurrence
