Abstract:: Objective To observe the spiral CT features of nodular goiter, and explore the feasibility of improving the diagnostic accuracy of nodular goiter by 64-slice spiral CT diagnosis. Methods CT findings in 53 patients with nodular goiters confirmed by operation and pathology were retrospectively analyzed and compared with pathological findings. Results Compared with normal controls, 53 patients had lower thyroid tissue density both on plain and enhanced CT scans. Among 53 patients, 45 patients developed with mixed cystic-solid nodules, 6 with cystic nodules and 2 with solid nodules. According to the distribution of focus, cases were divided into localized type (15 cases of single nodular goiter and 21 of multinodular goiters) and diffuse type (7 cases of one side and 10 of both two sides). Twelve cases of nodular goiters appeared calcification. In 2 cases, the focuses were too large to extend to the mediastinum. Conclusion The 64-slice spiral CT has certain values for diagnosing nodular goiter and evaluating the relationship between nodules and the surrounding tissues. However, the differential diagnosis of nodular goiter and thyroid adenoma remains challenge if the focus is signal nodular goiter.
