摘　　要：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 scans in differential diagnosis of thyroid neoplasm . Methods CT findings of thyroid neoplasm in 29 cases including 8 cases thyroid adenoma, 4 cases nodular goiter and 17 cases thyroid carcinoma identified by operation and pathology were analyzed retrospectively . Results The contour of thyroid adenoma was distinct , a completely enhanced ring in 5 cases and enhanced nodules in 3 cases were showed on contrast - enhanced scan. 4 cases of nodular goiter showed homogenous cystic low density the lesions were localized and distinct in contour , the cystic wall could be seen . Thyroid carcinoma appeared unhomogenous density , the edges contour of lesion was not distinct and infiltration on adjacent tissue might be seen. Conclusion CT scan might play an important role in diagnosis and differential diagnosis of thyroid neoplasm.
