Endoscopic transtubercular/transplanar approach. (A) Preoperative magnetic resonance image (MRI) shows a pituitary adenoma extending anteriorly to cause bilateral frontal base and optic nerve compression. (B) Endoscopic view after removing the tumor shows the frontal lobe anterior cerebral artery complex covered by arachnoid membranes. (C) Postoperative computed tomography after gross total resection of the tumor. Hydroxyapatite cement was used to achieve rigid reconstruction (black asterisk). (D) Postoperative MRI after gross total resection of the tumor.
