title: Whole-body MR imaging in detecting phosphaturic mesenchymal tumor (PMT) in tumor-induced hypophosphatemic osteomalacia.
abstract: We present 2 cases of tumor-induced osteomalacia (TIO). Both patients had histories of long-term bone and muscle pain. Laboratory data revealed hypophosphatemia. Whole-body magnetic resonance (MR) imaging (WB-MRI) clearly depicted a small subcutaneous mass in the left thigh of the first patient and a right acetabular mass in the second patient. These lesions were pathologically proven to be hemangiopericytoma-phosphaturic mesenchymal tumors (PMT).
