case_images: Subsequently to detect the source of FGF23, 68-Gadolinium DOTANOC positron emission tomography-computed tomography (PET-CT) scan of whole body [Figure 1] was done which revealed a large well-defined heterogeneously enhancing mass lesion 37 x 24 x 43 (anteroposterior x transverse x craniocaudal) mm in left nasal cavity with erosion of left middle turbinate and medial wall of left maxillary antrum showing increased tracer uptake.
