Intradiverticular Bladder Cancer Mimicking a Normal Urinary Bladder Diverticulum on FDG PET/CT
Xiaojun Man, Changming Dong, Aisheng Dong, Xiandong SongBladder diverticula are predisposed to developing intradiverticular bladder tumors. We describe FDG PET/CT findings in a case of intradiverticular bladder cancer. At FDG PET/CT (62 min), the intradiverticular bladder cancer appeared as an exophytic lesion with similar density to the urine in the bladder and intense activity mimicking a bladder diverticulum. At delayed pelvic FDG PET/CT (275 min), the tumor showed higher density and activity than the urine in the bladder, consistent with malignancy. This case indicates that delayed pelvic FDG PET/CT may be necessary for detecting possible intradiverticular bladder cancer in patient with bladder diverticulum.
