RESUMO
A 60-year-old man with prostate adenocarcinoma status post radical prostatectomy and bilateral pelvic lymph node dissection referred for restaging F-fluciclovine PET/CT due to rising serum prostate-specific antigen levels (1.1 ng/mL at that time of imaging). PET/CT images were obtained from the proximal thighs to the vertex of the skull approximately 3 to 5 minutes after the IV administration of 347.8 MBq (9.4 mCi) of F-fluciclovine. PET/CT imaging demonstrated a focus of abnormally increased F-fluciclovine uptake at the right ureterovesical junction. Subsequent MRI of the pelvis revealed that this focus corresponded to a benign ureterocele.

A case of milk-of-calcium with an exceptional location is reported. The characteristics of milk-of-calcium are presented, with stasis and urinary tract infection being the most important etiologic factors in this case. Structurally the stones are formed by a central core of calcium phosphate surrounded by magnesium-ammonium phosphate (struvite).
