case_images: (a and b) Coronal and sagittal T1-post contrast magnetic resonance imaging demonstrated a homogeneously enhancing anterior fossa lesion, dependent on the planum sphenoidale, which conditioned significant hyperostosis of the sphenoid bone. The lesion extended dorsally, leading to a right subfalcine herniation and compression of the frontal horns of the lateral ventricles and corpus callosum. In the sagittal projection, a hyperintense sellar mass confined to the sella turcica was also noted. (c and d) Coronal and sagittal postoperative non-contrast computed tomography revealed total tumoral removal of both meningioma and PitNET, associated with a significant anterior skull base bony defect, which was repaired as mentioned above.

case_images: In addition, a homogeneously enhancing sellar lesion with some areas of T1-weighted imaging shortening, compatible with a PitNET, was observed [Figure 1].

case_images: (a) Coronal T1-post contrast magnetic resonance imaging (MRI) demonstrated a heterogeneously enhancing sellar lesion, with suprasellar extension into the third ventricle and parasellar extension into the left cavernous sinus. (b) An anteroposterior angiogram of the left internal carotid artery showed a left paraclinoid aneurysm with a dorsomedial projection. (c) Coronal T1-weighted post-contrast MRI obtained two months after surgery revealed a gross total resection of the pituitary neuroendocrine tumors with a small remnant at the left cavernous sinus. (d) Postoperative computed tomography angiography demonstrated total aneurysm occlusion with preservation of the parental vessels and branches

case_images: Brain MRI revealed an isointense T1- and T2-weighted imaging sellar lesion, with heterogeneous contrast enhancement, extending upward into the third ventricle and with para sellar extension into the right cavernous sinus [Figure 2].
