case_images: 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.

case_images: Post-operative computed tomography scan showing complete excision of the hyperdense focus with the surrounding bone, amounting to a right D10 hemivertebrectomy.

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

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

case_images: 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].
case_images: Immunohistochemical staining showing a positive stain for Vimentin, a marker for mesenchymal cells.

case_images: Immunohistochemically, the tumor cells stained positive for Vimentin, thus confirming its mesenchymal origin [Figure 6].
case_images: 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.
