胸内甲状腺的CT特征与诊断价值(附七例分析)

CT Features and Diagnostic Values of Intrathoracic Thyroid

通过对手术病理证实7例胸内甲状腺的CT特征与诊断价值的研究,认为:(1)肿块与颈部甲状腺相延续;(2)肿块密度不均匀或伴钙化;(3)平扫肿块CT值接近或高于胸壁肌肉,增强后明显强化且有延迟增强表现;(4)对纵隔大血管及气管的典型推移表现,对诊断胸内甲状腺有肯定的价值。

CT features and diagnostic values of intrathoracic thyroid in seven patients confirmed surgico—pathologically were studied. The authors believed that following CT findings were definitely valuable in the diagnosis of intrathoracic thyroid: (1) continuity with the cervical thyroid gland; (2) well defined borders,nonhomogeneity or calcification; (3)precontrast attenuation values similar to or greater than that of mulscle, enhanced remarkably after intravenous contrast and delayed enhancement; (4) typical displacement of the great vesseles and trachea.
