摘要
的为提高骨显像对骨性原发性甲状旁腺功能亢进症(PHPT)的诊断效率,对117例PHPT患者骨显像特点进行分析。方法117例PHPT患者,男50例,女67例,其中116例为甲状旁腺腺瘤,1例为甲状旁腺腺癌,平均年龄61.1(12~86)岁。所有患者均行^99Tc^m-亚甲基二膦酸盐(MDP)显像,骨显像图分为4种类型:Ⅰ型骨显像阴性;Ⅱ型骨显像局部骨异常,即局灶型,又再分为2个亚型:ⅡA型颅骨和下颌骨放射性浓聚,ⅡB型表现为除有ⅡA型特点外,还存在其他局部骨代谢异常;Ⅲ型全身骨放射性摄取增加;Ⅳ型表现为全身+局部骨代谢异常。用χ^2检验和独立样本t检验进行统计学处理。结果117例骨显像表现为Ⅰ型者47例,占40.17%;Ⅱ型35例,占29.91%,其中ⅡA21例,ⅡB14例;Ⅲ型30例,占25.64%;Ⅳ型5例,占4.27%。70例Ⅱ、Ⅲ、Ⅳ型异常骨显像PHPT患者有骨折史、结石史、骨折+结石史、骨质疏松史和骨痛史,分别占55.71%(39例)、11.43%(8例)、10.00%(7例)、72.86%(51例)和37.14%(26例);而47例骨显像Ⅰ型者上述病史分别为2.13%(1例),0,0,21.28%(10例)和21.28%(10例)。两者各种病史发生率相比差异有统计学意义(χ^2=11.152,P=0.01)。Ⅱ、Ⅲ、Ⅳ型(骨显像异常)与Ⅰ型患者的肿瘤体积、甲状旁腺激素(PTH)、血钙、血磷分别为(14.52±13.72)cm^3和(0.78±1.33)cm^3、(731.67±618.40)ng/L和(112.04±62.98)ng/L、(3.05±0.29)mmol/L和(2.56±0.42)mmol/L、(0.71±0.14)mmol/L和(1.03±0.36)mmol/L,两者相比t=-5.724,-5.741,-7.274和-6.451,P均〈0.01,差异也有统计学意义。结论(1)约40%PHPT患者骨显像正常;(2)PHPT患者4种骨显像结果反映了骨损害的情况;(3)PHPT的骨显像特点有助于该病的鉴别诊断。
Objective To analyze the characteristics of bone seintigraphy in 117 cases with primary hyperparathyroidism (PHPT). Methods Of these 117 cases (50 males and 67 females) , there were 116 parathyroid adenomas and 1 parathyroid cancer. Mean age was 61.1 (12- 86 ) years old. All had ^99Tc^m- methylene diphosphonate (MDP) bone scintigraphy. The bone images could be classified into 4 categories. Category Ⅰ : normal; category Ⅱ : localized abnormal, which could be subcategorized as H A with skull and mandible involvement, and Ⅱ B with Ⅱ A characteristics plus metabolic derangement ; category Ⅲ : systemic, whole-body increased tracer uptake; category Ⅳ: systemic plus localized metabolic derangement. Data were analyzed statistically with χ^2 and t-test ( isolated samples). Results According to the scintigraphic findings, there were 47 cases (40.17%) of category Ⅰ , 35 cases (29.91%) category Ⅱ (21/35 cases Ⅱ A and 14/35 cases Ⅱ B) , 30 cases (25.64%) category Ⅲ, and 5 cases (4.27%) category Ⅳ. Combining categories Ⅱ , Ⅲ and Ⅳ together, there were 70 abnormal cases. These patients had history of abnormal bone images such as bone fracture (39 cases, 55.71% ), calculus (8 cases, 11.43% ), bone fracture plus calculus (7 cases, 10.00% ), osteoporosis (51 cases, 72. 86% ) or ostalgia (26 cases, 37.14% ) ; however, in the 47 cases of category Ⅰ, only 1 (2.13%), 0, 0, 10 (21.28%) and 10 cases (21.28%), respectively, were found. Therefore, these case history characteristics were statistically significant (χ^2 = 11. 152, P = 0.01 ). The tumor size, parathyroid hormone (PTH), blood calcium, blood phosphorus in the patients of abnormal PHPT categoriesⅡ to Ⅳ were ( 14.52 ± 13.72) cm^3, (731.67 ±618.40) ng/L, (3.05 ± 0. 29 ) mmol/L and (0.71 ± 0.14) mmol/L, respectively, with statistically significant difference compared to category Ⅰ : (0.78 ± 1.33) cm^3, ( 112.04 ± 62.98) ng/L, (2. 56 ± 0.42) mmol/L and ( 1.03 ± 0.36) mmol/L (t= -5.724, -5.741, -7.274 and -6.451; all P〈0.01). Conclusions (1)Bone scintigrapby was normal in 40% of PHPT patients. (2)The bone images of PHPT could be classified into 4 categories and each could reflect the duration and severity of the disease status on bone. (3)The bone imaging characteristic could be useful for differential diagnostic purposes.
