甲状旁腺腺瘤的螺旋CT表现及应用价值
|
摘要
目的探讨甲状旁腺腺瘤的螺旋CT表现,评估其在基层医院的应用价值。方法对8例经病理证实的甲状旁腺腺瘤的螺旋CT资料进行回顾性分析,所有病例均经薄层增强扫描。结果 8例甲状旁腺腺瘤均发生在下部甲状旁腺后方的气管-食管旁沟内,呈单发结节(右侧6例,左侧2例)。CT平扫呈椭圆形或类圆形边缘光滑软组织密度结节,与周围大血管密度相似,与甲状腺和周围组织分界清晰,直径约0.7cm～3.1cm,未见钙化,2例内部有坏死;CT增强结节呈均匀或不均匀强化,CT值低于周围大血管强化程度。8例均有不同程度骨质疏松,2例合并肾结石。结论螺旋CT在基层医院已经普及,因具有覆盖面广、采集信息量大、低剂量、扫描速度快、分辨率高和定位准确的突出优点,可以作为甲状旁腺腺瘤最常用和最重要的诊断方法。
Objective To investigate the spiral CT manifestations of parathyroid adenoma and evaluate its application value in primary hospitals. Methods The spiral CT data of 8 cases of pathologically confirmed parathyroid adenoma were retrospectively analyzed. All cases were scanned by thin-layer enhanced scanning. Results 8 cases of parathyroid adenoma occurred in the tracheal-esophageal sulcus behind the lower parathyroid gland, with a single nodule(6 cases on the right side and 2 cases on the left side).CT plain scan showed an elliptical or rounded edge smooth soft tissue density nodules, similar to the density of surrounding large vessels, clear boundary with thyroid and surrounding tissue, diameter of about 0.7 cm-3.1 cm, no calcification, 2 cases of internal necrosis. The CT-enhanced nodules showed uniform or uneven enhancement, and the CT value was lower than that of the surrounding large blood vessels.8 cases had different degrees of osteoporosis, and 2 cases had renal stones. Conclusion Spiral CT has been widely used in primary hospitals. It has the advantages of wide coverage, large amount of information collected, low dose,fast scanning speed, high resolution and accurate positioning. It can be used as the most common and important parathyroid adenoma diagnosis method.
