We treated an extremely rare thyroid-stimulating hormone (TSH)-producing pituitary adenoma in a 63-year-old woman with severe hypothyroidism due to autoimmune thyroiditis. She was presented with dizziness and fatigue. The blood level of TSH, prolactin, and fT4 was 288.2 μIU/mL, 72.9 ng/mL, and 0.24 ng/dL, respectively. Magnetic resonance imaging demonstrated a large pituitary tumor, 31 mm in height, and a normal pituitary gland. Preoperative thyroxine replacement reduced the TSH level to 2.05 μIU/mL and produced a significant reduction in the tumor volume. Histopathologically, the surgically removed tumor was a TSH-producing pituitary adenoma.
我们治疗了一名63岁患有自身免疫性甲状腺炎导致严重甲状腺功能减退的女性患者,她患有极其罕见的分泌促甲状腺激素(TSH)的垂体腺瘤。她出现头晕和疲劳症状。促甲状腺激素、催乳素和游离甲状腺素4的血液水平分别为288.2μIU/mL、72.9ng/mL和0.24ng/dL。磁共振成像显示一个大的垂体肿瘤,高31mm,垂体腺正常。术前甲状腺素替代治疗将促甲状腺激素水平降至2.05μIU/mL,并使肿瘤体积显著缩小。组织病理学检查显示,手术切除的肿瘤是分泌促甲状腺激素的垂体腺瘤。
