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.
