An avid focus on DOTATOC positron emission tomography (PET) scan [Figure 1] and a corresponding hyperdense focus on a plain computed tomography (CT) [Figure 2] suggested the possibility of a PMT of the left side of D10 vertebral body.

The entire area corresponding to the hot spot in the PET scan was drilled, along with a 3-4 mm margin [Figure 3].

His phosphate levels gradually normalized [Figure 4], muscle power returned to normal in all muscle groups and he could walk with minimal support.
Histopathological examination of the tumor showed spindle cells with an oval nucleus, minimal atypia, and no mitosis.

Histopathology revealed bony fragments infiltrated by a cellular tumor, composed of spindle cells in fascicles having an oval nucleus with moderate clear to pink cytoplasm and minimal atypia with no mitosis [Figure 5].
Immunohistochemical staining showing a positive stain for Vimentin, a marker for mesenchymal cells.

Immunohistochemically, the tumor cells stained positive for Vimentin, thus confirming its mesenchymal origin [Figure 6].
18-FDG positron emission tomography computed tomography on follow-up shows no evidence of any locoregional or distant hot spot suggesting no recurrence or metastasis.
