Vesico-colic fistula as demonstrated by [18F]FDG-PET

Incidental Detection of Urinary Leakage on FDG PET/CT Imaging

“…Several cases regarding incidental discovery of urinary leakage by 18 F-FDG PET/CT have been reported, caused by vesicovaginorectal fistula, sigmoidovesical fistula, or vesicocolic fistula. [4][5][6][7][8] Different from previous reports, our case demonstrates ureteral avulsion as a unique cause of urine leakage.…”

Positron Emission Tomography as a Diagnostic Tool in Infection: Present Role and Future Possibilities

“…The potential applications of FDG-PET imaging include evaluation of the complicated diabetic foot, [16][17][18] painful joint prosthesis, [19][20][21][22] fever of unknown origin (FUO), [23][24][25][26] acquired immunodeficiency syndrome (AIDS)-related disorders, 27,28 vascular graft infection and fistula, [29][30][31][32][33] and a variety of noninfectious inflammatory diseases (Table 1). [34][35][36] These conditions all are discussed in detail in this and the next issue of Seminars in Nuclear Medicine.…”

Inflammatory and Malignant Uptake Along Crohn Perianal Fistula on 18F-FDG

“…18 F-FDG PET/CT is typically utilized for the staging of varied gastrointestinal malignancies including anal SCC 1,7 . However, the use of 18 F-FDG PET/CT has evolved to include the identification of benign inflammatory conditions 2–6,8,9 . In one study including 212 patients, nonmalignant causes of incidental FDG uptake were assessed and a perianal fistula accounted for 1 of the 212 incidental findings 11 ; otherwise, perianal fistula uptake has not been systemically studied to the best of our literature search.…”

[2][3][4][5][6]8,9 In one study including 212 patients, nonmalignant causes of incidental FDG uptake were assessed and a perianal fistula accounted for 1 of the 212 incidental findings 11 ; otherwise, perianal fistula uptake has not been systemically studied to the best of our literature search. This case demonstrates the imaging findings of a perianal fistula on 18 F-FDG PET/CT that has similar uptake to an anal SCC.…”
