Abstract: Pituitary metastasis is a rare tumor complication, and papillary thyroid carcinoma is a tumor with low hematogenous dissemination tendency. Here we report a rare case with pituitary metastasis from papillary thyroid cancer. This patient was 43 years old and was admitted to our hospital because of " blurred vision in the right eye" . She had partial thyroidectomy because of thyroid nodule 8 years ago, and was diagnosed as papillary thyroid carcinoma, but without any further treatment onwards. After admission, MRI revealed a pituitary mass protruding through the sella turcica into the right sphenoid sinus. Neuro-endoscopic transsphenoidal resection was performed to relieve visual impairment. Pathological result was papillary thyroid carcinoma pituitary metastasis. She underwent thyroidectomy 2 months later. Because tumor of the left lobe invaded the esophagus, it was resected palliatively, and adjuvant therapy with radioactive iodine was performed subsequently. This case suggests that long-term management of papillary thyroid carcinoma should be strengthened to reduce the risk of recurrence and metastasis, additionally radioiodine therapy is an important complementary treatment.
