From: Intraoperative hypovolemia as a possible precipitating factor for pituitary apoplexy: a case report
Preoperative MRI shows pituitary macroadenoma (2.7 cm) with suprasellar extension and compression of optic chiasm, parasellar extension into right cavernous sinus, and extension into right sphenoid sinus on coronal T1 with contrast (a) and sagittal T2 FLAIR (b). Postoperative day 7 MRI demonstrates hemorrhage on coronal T2 (c) and sagittal T2 FLAIR (d). Postoperative week 10 MRI demonstrating resolution of hemorrhagic changes within pituitary gland, decrease in size of adenoma now limited to sella, and no mass effect on optic chiasm on coronal T1 without contrast (e) and sagittal T2 FLAIR (f)
