Abstract:
Objective: To observe ultrasonic manifestations of foreign body granulomas induced by suture stimulation in patients after thyroid surgery. Methods: Data of 47 papillary thyroid carcinoma patients who underwent total thyroidectomy or partial thyroidectomy were retrospectively analyzed. A total of 86 neck granulomatous nodules were diagnosed as surgical suture foreign body granuloma with ultrasonography, fine needle puncture cytology and clinical observation, and the ultrasonic characteristics and changes of nodules were observed. Results: All 86 suture granuloma nodules located in the margin of the residual thyroid gland or in the soft tissue around the surgical region, presenting as hypoechoic nodules without capsule, with irregular margin and punctate echogenic foci followed by some degree of acoustic shadowing. Color Doppler ultrasound showed that the blood flow signals were scarce in 80 nodules (80/86, 93.02%) and abundant in 6 nodules (6/86, 6.98%). Elastographic score was assessed, 24 nodules (24/86, 27.91%) were grade 2, 24 (24/86, 27.91%) were grade 3 and 38 (38/86, 44.19%) were grade 4. Conclusion: Ultrasonic characteristics of suture granuloma after thyroid surgery include mainly irregular hypoechoic in thyroid residual or surrounding neck soft tissue, with internal spot-like strong echo concentrated in the center of nodules.
