Abstract:
Schmorl's node (SN) is a common entity characterized by protrusion of intervertebral disc material through a break in the subchondral end plate of a vertebral body. They can show increased 99mTC methylene diphosphonate uptake on bone scintigraphy mimicking metastasis and can be symptomatic. Differentiation of SN from metastasis is essential for appropriate patient management. Here, we present a case where increased 99mTC methylene diphosphonate uptake in a dorsal vertebra was found to be because of SN by using single-photon emission computed tomography-computed tomography.
