BACKGROUND: Hemorrhoids are very common in adults. The data regarding the incidence of high 2-fluoro-2-deoxy-D: -glucose (FDG) uptake in hemorrhoids is incomplete. In this study, we evaluated FDG uptake in hemorrhoids and calculated the rate of high FDG uptake in these lesions. METHODS: One hundred and seventy six subjects who undertook whole body FDG-PET for health screening examination were investigated retrospectively. All patients had colonoscopy and 156 subjects were found to have hemorrhoids and 20 had no hemorrhoids. Quantitative analysis of FDG uptake in the anal region was performed by calculating the maximum standard uptake value (SUV(max)). RESULTS: The SUV(max) ranged from 1.8 to 4.1 (2.8 ± 0.6) for normal subjects and ranged from 1.4 to 8.3 (2.9 ± 0.8) for patients with hemorrhoids. No statistical difference was noted between these two groups using a Student's t-tests. If the highest SUV(max), which was 4.1 in normal subjects, was used as a cutoff, 5.1% (8/156) hemorrhoid patients had a SUV(max) greater than 4.1. CONCLUSION: Hemorrhoids can be one possible cause of focal high FDG uptake in the rectum.
