| 目的 探讨甲状旁腺腺瘤的螺旋CT表现。 方法 对8例经手术病理证实为甲状旁腺腺瘤的CT表现作回顾性分析。 结果 8例甲状旁腺腺瘤均起源于下甲状旁腺,右侧4例,左侧4例,均位于气管外血管内间隙。肿瘤最大径为1.0~5.0 cm,平均2.6 cm。平扫肿瘤呈等密度,1例肿瘤内有环形钙化。注射对比剂后8例肿瘤均有不同程度强化,其中2例肿瘤强化明显,接近于周围血管密度,增强后肿瘤呈均匀强化者5例,3例肿瘤内可见坏死不强化区。 结论 增强螺旋CT检查可准确显示甲状旁腺肿瘤的部位、形态、大小、强化特点及其与周围结构的关系,对临床诊治有重要价值。 |

| Objective To analyze spiral CT features of parathyroid adenoma. Methods Spiral CT findings were analyzed in 8 patients with pathologically proved parathyroid adenoma. Results All parathyroid adenomas were originated from inferior parathyroid gland (each side had 4 cases). All adenomas were located at recess between tracha and blood vessel. diameter of adenomas were 1.0-5.0 cm (2.6 cm on average). The adenomas showed isodensity on plain scan, one case showed ring calcification. After giving contrast medium, the adenomas revealed enhancement on different degrees, 2 cases enhanced obviously like blood vessels. Five cases of adenoms enhanced homogeneously, 3 cases showed non-enhancement in region of necrosis. Conclusion The post-contrast spiral CT can precisely assess the location, shape, size, enhancement features and the relationship with surrounding structures, which is valuable in diagnosing and treating parathyroid adenoma. |
