Increased ¹⁸F-FDG uptake associated with gastric banding surgical mesh on PET/CT

Surgical mesh was used in the 1980s and early 1990s for vertical banded gastroplasty as treatment for morbid obesity. This procedure was replaced by the more popular laparoscopic gastric banding in the mid-1990s. Surgical mesh, commonly used in hernioplasty, has been associated with increased ¹⁸F-FDG uptake related to an inflammatory foreign body reaction and is a known cause of false-positive PET scans. We present a case of increased ¹⁸F-FDG uptake related to surgical mesh in a patient who had undergone vertical banded gastroplasty.
