| 目的 比较慢性淋巴细胞性甲状腺炎(CLT)合并良恶性结节的MSCT特征,探讨MSCT的诊断和鉴别诊断价值。 方法 回顾分析经手术病理证实的74例(79个结节)CLT合并结节的MSCT表现,包括结节的大小、实质部分所占百分比、钙化、边缘、包膜、结节的强化方式及程度,并进行统计学分析。 结果 有81.82%(18/22)的恶性结节为完全实性,16例(16/57,28.07%)囊性为主的结节全部为良性结节(P均<0.05)。恶性结节钙化多于良性,多为细颗粒钙化,位于病灶内部(P均<0.05)。恶性结节边缘多不清,无包膜或包膜不完整,多均匀强化(P均<0.05)。良恶性结节在结节与结节外甲状腺组织平扫、动脉期及实质期CT值之比差异无统计学意义(P均>0.05)。 结论 MSCT有助于鉴别诊断CLT患者合并良恶性结节典型特征。 |

| Objective To compare MSCT features of benign and malignant nodules in patients with chronic lymphocytic thyroiditis (CTL), and to observe the value of MSCT in identification and diagnosis of these lesions. Methods MSCT findings, including the size, percentage of solid element, calcification, margin, capsule, the pattern and the degree of enhancement of 79 thyroid nodules in 74 patients with CLT were retrospectively analyzed, the differences of benign and malignant nodules were compared statistically. Results About 81.82% (18/22) malignant nodules were almost entirely solid, while 28.07% (16/57) benign nodules were mainly to cystic (all P<0.05). Malignant nodules more frequently appeared microcalcification and internal calcification than those of benign nodules (all P<0.05). Malignant nodules were likely to be ill-defined margin, lack capsule or insufficient capsule, homogeneous enhancement (all P<0.05). There was no significant differences between malignant and benign nodules in ratio of nodules and thyroid tissues outside nodules in plain, arterial phase, parenchymal phase (all P >0.05). Conclusion MSCT is helpful to differentiate benign and malignant nodules in CLT patients. |
