Tracheobronchial adenoid cystic carcinoma is a rare malignancy. To the best of our knowledge, its enhancement pattern on multiphasic contrast-enhanced multidetector computed tomography has not been reported. Herein, we report the computed tomography findings of three consecutive cases of tracheobronchial adenoid cystic carcinoma. All lesions presented a gradual enhancement pattern on multiphasic contrast-enhanced computed tomography. We speculate that the gradual enhancement pattern on multiphasic contrast-enhanced computed tomography could potentially serve as a characteristic imaging feature and may therefore be a clue to diagnose tracheobronchial adenoid cystic carcinoma.

气管支气管腺样囊性癌是一种罕见的恶性肿瘤。据我们所知，其在多期多排螺旋 CT 增强扫描中的增强模式尚未有报道。在此，我们报道了连续 3 例气管支气管腺样囊性癌的 CT 表现。所有病变在多期增强 CT 上均表现为逐渐增强的模式。我们推测，多期增强 CT 上的逐渐增强模式可能是一种特征性的影像学特征，因此可能是诊断气管支气管腺样囊性癌的线索。J. Med. Invest. 67 : 378-381, August, 2020.
