A 55-year-old male patient with left hemianopia and pathologically confirmed NFPA. (A) Coronal CE T1WI shows an enhancing sellar tumor (red outline) with upward suprasellar extension and bilateral cavernous sinus invasion, causing compression of the optic chiasm and the third ventricle (arrow indicates area of optic chiasm and third ventricle). (B) The tumor (red outline) is segmented on coronal CE T1WI (A) and then mapped to the coronal T2WI (B). (C) Improvement of blurred vision after subtotal tumor resection via transsphenoidal approach is clinically documented, and the maximum height of the residual tumor (arrowheads) measured from coronal CE T1WI is 38 mm. (D) Recurrent visual deterioration with enlargement of the residual tumor (curved arrow) with maximum height up to 48 mm is observed 19 months after surgical resection.
