A 32-year-old woman with a history of Graves' disease had an episode of thyrotoxicosis 2.5 months after her first childbirth. Because of low thyroidal uptake of Tc-99m pertechnetate, a diagnosis of postpartum painless thyroiditis was made and the patient was observed without medication. After the normalization of serum levels of thyroid hormones, a second wave of thyrotoxic symptoms emerged. This time, the Tc-99m uptake was slightly elevated and the patient was diagnosed to have a relapse of Graves' disease. This case underscores the previously reported notion that thyroidal uptake was indispensable to distinguish these two causes of postpartum thyrotoxicosis.
一名有格雷夫斯病病史的32岁女性在首次分娩后2.5个月出现了一次甲状腺毒症发作。由于高锝酸盐Tc-99m的甲状腺摄取率低，诊断为产后无痛性甲状腺炎，对该患者未用药进行观察。在甲状腺激素血清水平恢复正常后，出现了第二波甲状腺毒症症状。这一次，Tc-99m摄取率略有升高，该患者被诊断为格雷夫斯病复发。该病例强调了先前报道的观点，即甲状腺摄取对于区分产后甲状腺毒症的这两种病因是必不可少的。
