Among pituitary adenomas, which are relatively common brain tumors, elements of ectopic, thyroid-stimulating hormone (TSH) secretion, and intratumoral calcification are unusual. Here, we present an extremely rare case of a calcified ectopic TSH-secreting pituitary adenoma arising from the pars tuberalis mimicking craniopharyngioma based on neuroimaging findings. To our knowledge, this is the first case report of calcified ectopic TSH-secreting pituitary adenoma without symptoms of excessive thyroid hormone secretion.
在相对常见的脑肿瘤——垂体腺瘤中，异位、促甲状腺激素（TSH）分泌和肿瘤内钙化的元素并不常见。在这里，我们报告了一例非常罕见的基于神经影像学表现的源于结节部的伴有钙化的异位 TSH 分泌性垂体腺瘤，类似于颅咽管瘤。据我们所知，这是首例无甲状腺激素分泌过多症状的伴有钙化的异位 TSH 分泌性垂体腺瘤病例报告。
