目的 :对原发性甲状旁腺机能亢进症 (PHPT)的骨骼X线改变进行探讨。方法 :对手术治疗病理确诊的 2 0例原发性甲状旁腺机能亢进症的临床资料及X线表现进行回顾性分析 ,本组病例均行头颅骨、双手、骨盆及胸部X线检查 ,部分病例行脊柱、腹部、四肢X线检查。结果 :全身性骨质疏松 2 0例 ,2 0例中同时伴有指骨骨膜下骨吸收 19例 ,纤维囊性骨炎 17例 ,颅盖骨的磨玻璃或颗粒样变 16例 ,颌骨牙槽骨吸收 17例。结论 :全身骨骼广泛性骨质疏松及指骨骨膜下骨吸收是X线诊断本病的一个重要征象 Objective: To explore the change of skeletal X-ray of primary hyperparathyroidism (PHPT). Methods: The clinical data and X-ray findings of 20 cases with primary hyperparathyroidism confirmed by pathology were retrospectively analyzed. The skull, hands, pelvis and chest X-ray examination were performed in this group of patients. In some cases Spine, abdomen, limb X-ray examination. Results: 20 cases of systemic osteoporosis, 20 cases were accompanied by subperiosteal bone absorption in the phalanges of 19 cases, 17 cases of cystic fibrosis, calyx bone grinding or granular changes in 16 cases, jaw teeth Slot absorption in 17 cases. CONCLUSIONS: Generalized skeletal extensive osteoporosis and subperiosteal bone resorption of the phalanges are an important symptom of X-ray diagnosis of this disease
