Oncogenic osteomalacia is rare disease predominantly caused by a small, somatostatin receptor
positive mesenchymal tumor, which is frequently hidden in an unusual anatomical site and
often goes undetected by conventional imaging. A permanent cure of the disease relies on
exactly localizing the tumor and completely removing it. 68Ga-DOTATATE PET/CT is a novel scan
that might have improved sensitivity and resolution specifically for somatostatin receptor
positive tumors. The investigators will scan the suspicious and confirmed patients of
oncogenic osteomalacia and compare it to 99mTc-HYNIC-TOC SPECT/CT and 18F-FDG PET/CT to see
if it improves patient care.
