Abstract:
Neoplasms that cause tumor-induced osteomalacia are very rarely located in the lung. A 27-year-old man underwent a surgery in the right femoral head to remove the tumor that induced osteomalacia 8 years ago with complete symptomatic relief. However, his bone pain occurred again recently, which lead to suspicion of a recurrent tumor-induced osteomalacia. 68 Ga-DOTATATE PET/CT images showed a pulmonary nodule with mildly increased uptake along with increased activity in the left foot. The pulmonary nodule was subsequently resected and was pathologically confirmed as a phosphaturic mesenchymal tumor. The symptoms were completely relieved postsurgery.
