Unusual iodine‐131 postablation whole‐body scintigraphy patterns in patients after robot‐assisted/endoscopic thyroidectomy: Case series

Abstract

Abstract Robot‐assisted/endoscopic thyroidectomy causes irritation due to instruments or implantation of thyroid tissue on the anterior chest wall and lower neck. We present three patients who exhibited unexpected focal lesions on postablation Iodine‐131 single‐photon emission computed tomography/computed tomography without biochemical and structural diseases. Meticulous surgical techniques are important to prevent complications.
