Normal and abnormal sonographic findings at the thyroidectomy sites in postoperative patients with thyroid malignancy.

Abstract

We describe typical sonography characteristics of locally recurrent tumors after thyroidectomy for thyroid cancer and the benign conditions mimicking tumor recurrence, with an emphasis on the differential diagnosis. Ultrasound is an effective imaging technique not only for the detection of locally recurrent tumors but also for the differential diagnosis of locally recurrent tumors and other abnormalities mimicking tumor recurrence.
