Presentation transcript:

A 68-year-old woman with acute back pain of 15-day duration. A 68-year-old woman with acute back pain of 15-day duration. Schmörl's node formation with herniation of calcified disk. A, T1-weighted image spin-echo (600/15 [TR/TE]) shows diffuse low signal intensity in the T11 vertebral body and spondylolisthesis of L5–S1. T2-weighted spin-echo image (2200/80) shows only slight increase in signal intensity near inferior endplate (arrow).B, Increased uptake on bone scintigraphy over T11 vertebra 6 days later.C, CT scan depicts a radiolucent lesion in lower portion of T11 with central dense bone 14 days later.D, Small defect (arrow) in inferior vertebral endplate of T11 and decrease in vertebral hypointensity on T1-weighted spin-echo image (500/15) 3 months later.E, CT coronal reformatted images. Disk calcification herniating through vertebral bony defect.F, T1-weighted spin-echo image (460/17) and T2-weighted spin-echo image (5000/112) (arrow) show a typical Schmörl's node at 1-year follow-up.
