The patient did not gain weight as well as his monozygotic twin brother (Figure 1).
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).

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.
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.

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