Abstract Objective: To study features of minor salivary gland tumors on the CT and MR image. Methods: The CT, MR image and clinical information of 31 patients with surgery and pathology confirmed tumors of minor salivary glands were retrospective analyzed. Result: Fourteen cases of minor salivary gland tumors among 31 cases were benign tumors, and most of them were adenoma. The average diameter of tumors was 2.3 cm, most tumors located in the palatine. Tumors were shown soft tissue density on CT, low or equal signal on T1WI and slightly higher signal on T2WI. Thirteen cases were well-defined and 4 cases had bone oppression. Tumors were moderate enhancement in the post-enhanced scan. Malignant tumors were seen in 17 cases, most of them were adenoid cystic carcinoma. They often appeared in the palatine. Most of them were shown mixed low density on CT, mixed slightly low signal on T2WI, few of them were shown slightly high signal. Fourteen cases were with unclear boundary and bone destruction. Tumors were mild to obvious heterogeneous enhancement in the post-enhance scan. Conclusion: CT and MRI are of considerable value in diagnosis and differential diagnosis of minor salivary gland tumor.
