Evaluation of tumor-induced osteomalacia with 111in-pentetreotide scintigraphy

Abstract

In cases of nonhereditary osteomalacia associated with hypophosphatemia and inadequate response to vitamin D supplementation, one should consider the possibility of tumor-induced osteomalacia, a paraneoplastic syndrome caused by small mesenchymal tumors often found in obscure locations. We present a case of tumor-induced osteomalacia in which 111In-pentetreotide scintigraphy aided in accurate localization of the culprit brachial plexus tumor and cure after resection. © 2013 by the Society of Nuclear Medicine and Molecular Imaging, Inc.
