Pathological examination results of tumor resection. (A) The first surgical pathology results in 2017: meningioma (meningeal epithelial type, WHOI grade). (B) Immunohistochemical results of meningioma in 2017: GFAP(-), Ki-67(1%+), S-100(-), PR(3+), EMA(3+), CK7(-). (C,D) Postoperative histological examination of the tumor in the sellar region showed meningioma (meningeal epithelial type and WHO I grade), and the immunohistochemical results were as follows: GFAP(-), Ki-67(1%+), S-100(-), PR(2+), EMA(3+). (E,F) The immunohistochemical results of recurrent pituitary adenoma in the sellar region were as follows: EMA (3+), Syn (2+), Ki-67 (1%+), and PR (2+).

The postoperative pathological results showed meningioma, meningeal epithelial type, and WHO I type (Figures 1A,B). The pathological results of the tumor after the second operation showed meningioma, meningeal epithelial type, WHO grade I (Figures 1C,D); pituitary tumor, some pituitary adenomas, and some meningiomas (Figures 1E,F).
Preoperative head MRI and postoperative head CT examination were performed. (A) An enhanced MRI scan of the head before the first operation, the red arrow points to the pituitary fossa mass. (B) In the first postoperative CT scan, the red arrow points to the complete resection of the meningioma tumor. (C) T1-weighted enhanced coronal image before the second operation, the red arrow points to the same shadow of the newly formed T1T2 signal in the post-saddle region. (D) In the second postoperative CT scan, the red arrow points to the complete resection of the sellar mass.

The MRI report showed that the operative area was enhanced with flaky patches (Figure 2C), possibly a pituitary tumor. The patient's visual acuity improved after surgery, and the neurological examination was normal at the time of discharge (Figure 2D). T1-T2 signal mass shadows could be seen in the operation area. The tumor body wrapped around the internal carotid artery on enhanced scan and pushed upward to press the optic chiasma (Figure 2C).
