(A,B) Preoperatively, contrast-enhanced MRI of the sellar area showed the dimeter and shape of the tumor. (C) The texture of this tumor was tough, and bleeding occurred in the A2 branch of the ACA intraoperatively (red dotted line box is the bleeding area, and the upper left corner is an enlarged image of the bleeding). (D) GTR of the tumor after completion of electrocoagulation and hemostasis of the A2 branch of the ACA (yellow arrow). (E) Walking instability occurred at POD5. Diffusion-weighted imaging shows recent infarction of the left caudate nucleus head. (F) CT reexamination at POD10 reveals muscle strength returned to normal and the patient could move freely. (G,H) One year after surgery, contrast-enhanced MRI of the sellar region showed that the tumor had been completely resected, and that there was no sign of residual tumor or recurrence.
