case_images: Preoperative imaging of Case 2: A to C.- Axial, coronal and sagittal T1 with contrast MRI images showing a solid enhancing lesion (red arrowhead) in the suprasellar space, D. CT image shows no calcification

case_images: Fig4
case_images: A brain MRI showed a predominantly solid lesion in the suprasellar space involving the pituitary stalk and compressing the optic chiasm (Fig. 4). There was no calcification noted on the CT scan (Fig. 4d).
case_images: Intraoperative ultrasound images of Case 2 (before incising the dura) showing a heterogeneous lesion with few very hyperechoic areas suggestive of calcific foci (red arrowhead) along with the acoustic shadow. Hypoechoic cystic areas are also seen

case_images: Fig5
case_images: There were several hyperechoic areas with acoustic shadows suggestive of calcific foci (Fig. 5).
case_images: Postoperative T1 weighted MRI with contrast done 6 weeks post resection, shows a gross total resection of the tumor with preservation of the pituitary stalk and optic chiasma

case_images: Histopathology confirmed an ACP, and the postoperative MRI scan showed no residue (Fig. 6).
case_images: Preoperative MRI images of 2 other cases of PCP with corresponding intraoperative IOUS image (all taken before the dural incision): A. and B.- Preoperative axial T1 with contrast MRI image and the corresponding intraoperative IOUS image of a case of PCP (third patient in the series), C. and D.- Preoperative coronal T1 with contrast MRI image and the corresponding intraoperative IOUS image of another case of PCP (fourth patient in the series)

case_images: To further investigate the characteristic IOUS features of CPs, IOUS images of five consecutive (three PCP and two ACP) patients who underwent endoscopic endonasal transsphenoidal resection for CPs were retrospectively evaluated (Figs. 7 and 8).
