Radioactive Iodine Uptake in Postoperative Seroma: A Cause for False Positivity

Abstract

Besides the known physiologic uptake of ¹³¹I, the literature describes various false-positive findings on ¹³¹I scans in benign lesions, inflammation, traumatic sites, and postsurgical sites, to name a few. However, to the best of our knowledge, no study has shown false-positive uptake of ¹³¹I in a postoperative seroma at the postsurgical site. We describe such a case here.
