case_images: Radiological findings. A : T1-weighted axial MRI reveals a hypointense regular-shaped cystic lesion at the ventricular border. B : Contrast-enhanced T1-weighted coronal MRI reveals that the lesion compresses the optic chiasma and elevates the third ventricle and identifies the contrast-enhanced solid hyperintense nodule at the right floor of the lesion, just above the suprasellar internal carotid artery. C : Hyperintense cystic lesion on T2-weighted axial MRI. D : Tumoral invasion of the planum sphenoidale, whole sellar area, and suprasellar cistern.

case_images: T2-weighted images, the lesion was hyperintense, also compatible with a cystic lesion. The suprasellar cistern was filled and the optic chiasm and third ventricle were elevated by the lesion (Fig. 1).
case_images: Histology reveals the tumor's papillary structure with one or more layers of columnar epithelial cells around a fibrovascular core (H&E, x40).

case_images: On the basal right side of the lesion, a yellowish vascular nodule adjacent to the suprasellar internal carotid artery was revealed (Fig. 2) and completely excised while preserving the internal carotid artery.
case_images: Micrograph of immunostained section shows positive expression of pancytokeratin (x10).

case_images: The tumor was thus diagnosed as CPP (Fig. 3, 4).
case_images: T1-weighted contrast enhanced axial (A) and T2-weighted sagittal (B) postoperative MRI show total excision of the tumor.
