Advanced tumour-induced osteomalacia secondary to sinonasal phosphaturic mesenchymal tumour. SA Journal of Radiology, 28(1), p.2975.https://doi.org/10.4102/sajr.v28i1.2975https://hdl.handle.net/10566/19707Phosphaturic mesenchymal tumours (PMT) are rare, benign lesions and the most common tumour to cause tumour-induced osteomalacia (TIO), a paraneoplastic syndrome. Patients frequently exhibit severe osteomalacia, accompanied by multiple fractures, which significantly impair their quality of life. Complete surgical resection is curative. Contribution: A rare case of sinonasal PMT is presented, with a focus on the imaging findings and role of the radiologist and nuclear physician.enfracturesinducedmesenchymalnuclearosteomalaciaArticle
