(A-D) Preoperative CT and MRI examination showed a large tumor in the sellar area. (A) CT bone window showed Bone thinning in the left region of occipital base, slope, medial lateral plate of left pterygial process, sphenoid bone and left superior ethmoid sinus wall. (B) CT plain scan showed a hypointense mass with an indistinct boundary located in the saddle area, sphenoid sinus area, and left temporal lobe. (C) MRI showed a giant irregular mass in the left saddle area with non-uniform iso-/hypointense on T1-weighted imaging (D) and uniform hyperdense on T2-weighted imaging. (E, F) Postoperative CT imaging examination showed that the tumor was resected.

A CT scan revealed a hyperintense mass with an indistinct boundary located in the saddle area, sphenoid sinus area, and left temporal lobe; the tumor demonstrated expansive growth (Figure 1A and B). The tumor presented as non-uniform hyperintense signal on T1-weighted images and uniform hyperdense signal on T2-weighted images (Figure 1C and D). Postoperative CT imaging on the first day after surgery showed that the tumor was resected (Figure 1D-F).
