Diuretic ~68Ga DOTANOC PET/CT in Imaging of Bladder Paraganglioma

摘要

Urinary bladder paragangliomas are exceedingly rare tumors. A 22-year-old woman with bladder paraganglioma underwent ~68Ga DOTANOC PET/CT for proper localization of the primary tumor and to rule out locore-gional and distant metastases. ~68Ga DOTANOC-avid bladder mass was detected with no other abnormal site of radiotracer uptake elsewhere. Although radioactive urine can mask urinary paragangliomas, diuretic method can aid tumor detection by ~68Ga DOTANOC PET/CT.
