Radioactive iodine uptake in post-operative seroma: a cause for false positivity.

Besides the known physiological uptake of 131 I, literature describes various false-positive findings on 131 I scans in benign lesions, inflammation, traumatic sites, and post-surgical sites to name a few. However, no study to the best of our knowledge has shown the false-positive uptake of 131 I in a post-operative seroma at the post-surgical site.
