case_images: The patient did not gain weight as well as his monozygotic twin brother (Figure 1).
case_images: Preoperative (a, b) and postoperative (c, d) pituitary MRI results. Coronal T2-weighted image (a) and T1-weighted image with contrast enhancement (b) showed a pituitary lesion that was hyperintense on T2-weighted image and hypoenhancing compared with the surrounding pituitary parenchyma on T1-weighted image (arrows). The postoperative pituitary MRI showed no evidence of recurrence (c, d).

case_images: T2-weighted image (Figure 2(a)), which was less enhancing than the surrounding pituitary parenchyma (Figure 2(b)) and measured 5 x 6 x 7 mm in size. This lesion was suspected to be a pituitary microadenoma. MRI of the pituitary gland after 1 (Figure 2(c)) and 2 years (Figure 2(d)) showed the complete removal of the tumor, with no recurrence.
case_images: Hematoxylin and eosin staining of the patient's pituitary adenoma (a, b, x 200). Tumor tissue was composed of cytoplasmic-rich glandular cells arranged in clusters and featuring rounded nuclei. Cells arranged around the blood vessels and formed papillary structures with little mitosis.

case_images: PTU to prevent thyroid storm during surgery. Postoperative pathology results revealed an adenoma of the pituitary gland (Figure 3).
case_images: TSH and FT4 assay results showed decreasing trends after treatment.
