Unexpected Detection of Urinary Bladder Cancer on Dual Phase 18F-NaF PET/CT in a Patient With Back Pain.
A 72-year-old man underwent F-NaF PET/CT to evaluate causes of lower back pain. The PET images revealed multiple foci of increased activity in several vertebral bodies, which might account for the patient's symptoms. In addition, the CT image revealed partially calcified soft tissue mass in the posterior wall of the urinary bladder, which was photopenic relative to the radioactive urine on early PET images but became intense on delayed PET images. The diagnosis of transitional cell carcinoma was made pathologically after a transurethral resection of the mass.
