摘要
目的 探讨CT扫描结合核素显像在甲状腺肿瘤鉴别诊断中的价值。方法 回顾性分析经手术及病理证实的 5 4例甲状腺肿瘤的CT表现及核素显像结果 ,其中甲状腺腺瘤 4 0例 ,甲状腺癌 14例。结果 CT扫描 4 8个腺瘤病灶中有 4 0个包膜完整 ,其中 37个囊腺瘤病灶均有完整性强化环。 15个甲状腺癌病灶中有 12个边界模糊 ,7个呈“强化残圈”征 ,5个有强化瘤壁结节 ,4个乳头状癌病灶侵犯周围组织。核素显像甲状腺腺瘤 4 5个结节中 ,热结节 4个 ,温结节 8个 ,凉冷结节 33个。甲状腺癌 15个甲状腺结节中均为凉冷结节。结论 CT扫描结合核素显像可以使我们对于甲状腺肿瘤的性质有更进一步的认识 ,从而有利于鉴别诊断。对于核素显像为热结节、温结节者 ,首先应考虑为良性病变 ,为凉冷结节者应密切结合CT征象。
Objective To evaluate the value of CT and nuclide scan in differential diagnosis of thyroid neoplasm.Methods 54 cases of thyroid neoplasm including 40 cases of thyroid adenoma and 14 cases of thyroid carcinoma proved by operation and pathology were analyzed retrospectively.Results In 48 focuses of thyroid adenoma,there were 40 focuses with complete theca and 30 focuses with well-defined enhanced ring.In 15 focuses of thyroid carcinoma,there were 12 focuses with untidy margin,7 focuses with no complete enhanced ring around the tumor,5 focuses with enhanced nodule on the wall and 4 focuses of thyroid papillary carcinoma with infiltration into the adjacent structures.In nuclide scan,there were 45 nodi of thyroid adenoma including 4 “hot nodi”,8 “warm nodi” and 33 “cool or cold nodi”. All of 15 nodi of thyroid carcinoma were of “cool or cold nodi”.Conclusion Combined CT and nuclide scan have a significant value in differential diagnosis of thyroid neoplasm.To the “hot nodus” or “warm nodus” diagnosed by nuclide scan,we should first diagnose it as benign tumor ,but to the “cool or cold nodus”,we should analyze it by the sign of CT.additionally.
