Previous studies have shown that thyroid hormone directly stimulates bone resorption in in vitro organ culture, and in adults excess thyroid hormone is associated with decreased bone mineral density. There are limited data in children regarding the effect of hyperthyroidism on bone metabolism and even fewer instances in the literature of hyperthyroidism presenting with bone demineralization and fracture. We report a case of an 11-year-old boy with undiagnosed hyperthyroidism presenting with fractures and osteoporosis. This case emphasizes the importance of maintaining a broad differential diagnosis when a patient presents with a pathologic fracture.
以往的研究表明,甲状腺激素在体外器官培养中可直接刺激骨吸收,在成年人中,甲状腺激素过多与骨矿物质密度降低有关。关于甲状腺功能亢进对儿童骨代谢影响的数据有限,而文献中甲状腺功能亢进伴骨脱矿质和骨折的病例更是少之又少。我们报告一例11岁未确诊甲状腺功能亢进的男孩,其表现为骨折和骨质疏松。该病例强调了患者出现病理性骨折时进行广泛鉴别诊断的重要性。
