A serum fibroblast growth factor 23 level was markedly elevated and a diagnosis of tumour-induced osteomalacia was considered. Whole body imaging revealed multiple insufficiency fractures but no osseus tumours. There was, however, a durally-based intracranial lesion whose imaging characteristics were consistent with a meningioma. The tumour was removed, leading to rapid normalisation of the patient’s symptoms and serum markers. Histology confirmed a phosphaturic mesenchymal tumour. We review the literature regarding this rare clinical situation. ER -
