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.

Histopathology was turned out to be mesenchymal tumor with no atypical mitoses or infiltrative margins [Figures 2 and 3].
