目的探讨CT对甲状腺良恶性肿瘤的诊断及鉴别诊断价值。方法分析经手术病理证实的29例良恶性甲状腺肿瘤的CT表现,其中甲状腺腺瘤8例,结节性甲状腺肿4例,各种恶性肿瘤17例,并进行统计学处理。结果腺瘤边界清晰,增强扫描5例显示完整强化环,3例表现为结节样强化。4例结节性甲状腺肿病灶局限,表现为囊性低密度影,边缘光滑,可见到囊壁。恶性甲状腺肿瘤成等或混杂密度,边界不清,强化不均,并向邻近组织侵犯。结论CT在甲状腺肿瘤的诊断和鉴别诊断中具有重要价值。
Objective To investigate the value of CT in the diagnosis and differential diagnosis of benign and malignant thyroid tumors. Methods The CT findings of 29 cases of benign and malignant thyroid tumors confirmed by surgery and pathology were analyzed. Among them, 8 cases were thyroid adenoma, 4 cases were nodular goiter and 17 cases were malignant tumor. Statistical analysis was performed. Results The adenoma had a clear boundary. In 5 cases of enhanced adenoma, complete enhancement ring was found and in 3 cases showed nodular enhancement. 4 cases of nodular goiter lesions, manifested as cystic low density, smooth edges, visible wall. Malignant thyroid tumors into the same or mixed density, the border is unclear, uneven reinforcement, and violations of neighboring organizations. Conclusion CT is of great value in the diagnosis and differential diagnosis of thyroid tumors.
