目的:探讨甲状旁腺腺瘤的多层面螺旋CT表现特征。方法:对11例经手术病理证实为甲状旁腺腺瘤的CT表现特点进行回顾性分析,全部病例进行多层螺旋CT平扫和增强CT扫描,部分病例进行多平面重建。结果:11例中,女性9例,男性2例,年龄29岁～75岁,平均年龄43岁,发生在甲状腺下极后方气管食管旁沟内8例,甲状腺上极气管食管旁沟内3例,肿瘤伴有钙化者1例,多层螺旋CT表现为甲状腺上、下极附近的气管食管旁沟内圆形或椭圆形软组织密度结节及肿块影,边缘光滑整齐,边界清楚,密度均匀或不均匀,常可见坏死囊变区,很少一部分肿瘤可有钙化,钙化呈结节样或点状,肿瘤周围脂肪间隙显示清晰,增强后肿瘤明显均匀或不均匀强化,肿瘤体积较大时邻近气管、颈部血管、肌肉及甲状腺可有受压推移改变。结论:多层螺旋CT能够清楚地显示甲状旁腺腺瘤结节及肿块的部位、大小、形状、数目和内外部特征。
Objective: To investigate the multi-slice spiral CT features of parathyroid adenoma. Methods: The CT findings of 11 cases of parathyroid adenoma confirmed by surgery and pathology were analyzed retrospectively. All patients underwent multislice CT scan and enhanced CT scan. In some cases, multiplanar reconstruction was performed. Results: Among the 11 cases, 9 were female and 2 were male, ranging in age from 29 to 75 years with a mean age of 43 years. They occurred in 8 cases of posterior thyroidectomy in the posterior tracheal esophagus, 3 cases in the thyroid gland, , Tumor with calcification in 1 case, multi-slice spiral CT showed thyroid, near the lower pole of the tracheoesophageal gland next to the circular or oval soft tissue density nodules and mass shadow, the edge of the smooth and tidy, clear boundary, uniform density or Not uniform, often seen necrotic cystic area, a small part of the tumor may have calcification, calcified nodular or punctate, the fat gap around the tumor showed a clear enhancement after the tumor was significantly uniform or uneven enhancement of tumor size larger adjacent Tracheal, cervical blood vessels, muscles and thyroid may be subject to changes in pressure. Conclusion: MSCT can clearly show the location, size, shape, number and internal and external features of parathyroid adenoma nodules and masses.
