摘要
甲状旁腺机能亢进症(甲旁亢)和青少年特发性、绝经期、老年性等普遍性骨质疏松(骨疏松)的X线片均可呈骨密度普遍下降,临床表现也有相似处(如骨痛、身高变矮等)。甲旁亢虽有血钙增高而有别于骨疏松,但甲旁亢有血钙不高或间歇性增高者。
Generalized lowering of bone density in hyperparathroidism(HPT)resembles osteoporosis of various causes in certain aspects. For differentiation, the presence of the following findings favors the diagnosis of HPT.1. Diminished cortical density of digital and metacarpal bones with brush like or lace like outlines and even slenderness of these bones due to subperiosteal absorption;2. Small cystic defects in the cortices of long bones;3. Absorption of cortex, irregular cortical outlines and slenderness of rib;4. In addition, the appearance of ground glass like or cotton like areas of increased density and/or signs of osteomalaeia or rickets in any bone is suggestive of HPT.
