case_images: Preoperative imaging examination of the reported patient. Left and Middle: Sagittal and coronal T1 MR imaging after injection of gadolinium. Both pictures showed massive masses in the sellar fossa and suprasellar cistern. Right: Computed Tomography Angiography (CTA) showed an aneurysm at the anterior edge of the anterior communicating artery, with a diameter of about 0.5cm.

case_images: Detailed preoperative imaging is presented in  Figure 1 .
case_images: Intraoperative nasal endoscopic images of the reported patient. Left: After resection of sellar region masses and opening of dura mater, it can be seen that the aneurysm was located in the anterior communicating artery. Right: The aneurysm neck was clamped with 3 aneurysm clips and the bilateral A2 filled well.

case_images: The intraoperative nasal endoscopic images are shown in  Figure 2 .
case_images: Imaging examination of the reported patient after operation. Left and Middle: Pituitary enhanced MRI showed complete removal of sellar region lesion 3 days after operation. Right: Catheter-based cerebral angiography indicated no obvious abnormality after clipping of anterior communicating artery aneurysm.

case_images: The results of CTA 1 day after the operation showed that the aneurysm was well clipped, and pituitary enhanced MRI showed complete removal of the sellar region lesion 3 days after the operation ( Figure 3 ).
case_images: The detailed images reexamined 6 months after operation. Left and Middle: Pituitary enhanced MRI showed no recurrence of the pituitary adenoma 6 months after operation. Right: Computed Tomography Angiography (CTA) 6 months after operation showed the aneurysm was well clipped.

case_images: Pituitary MRI scans indicated no evident signs of tumor recurrence, and the CTA confirmed the aneurysm was successfully clipped.  Figure 4  presents the imaging taken six months following the surgery.
