Abstract

⁶⁸Ga-DOTATATE uptake in mesenchymal tumors causing hypophosphatemic osteomalacia has been recently described. Herein, we present a case of ⁶⁸Ga-DOTATATE uptake in an intramastoid phosphaturic mesenchymal tumor that had not been depicted in previous (99m)Tc-Sestamibi and ¹â¸F-FDG scans. The lesion was surgically removed and the phosphorus level increased to the normal range.
