Extraperitoneal urinary bladder perforation detected by FDG PET/CT.

Accurate localization of areas of increased metabolic activity on PET only imaging can be challenging. Fusion of PET with CT imaging provides anatomic detail which aids in localization of functional information. As a result, the overall sensitivity and specificity of information provided by PET or CT alone is improved with combined PET/CT resulting in improved diagnosis and patient management. We report a case of an unexpected emergent finding of urinary bladder perforation on PET/CT to stress the importance of accurately interpreting the anatomic and functional data. To our knowledge, diagnosis of bladder perforation on PET/CT has not been previously reported in the literature. Failure to recognize such complications may lead to adverse outcomes.
