Initial X-rays showed disc calcification without any fractures [Figure 1].
Magnetic resonance imaging with axial T5/6 (a) and sagittal (b) views taken during hospital day 0 showing disc calcification with herniation causing spinal cord compression of T4-6. T5 vertebrae are flattened posteriorly with hypointense signal indicative of calcification.

T4-T6. The discs were involved at T4/5 and T5/6, with a flattened T5 vertebrae posteriorly, and hypointense signal indicative of calcification [Figure 2].
Computed tomography with axial (a) and sagittal (b) views shows T4/5 and T5/6 disc calcification in the anterior epidural space causing severe spinal canal stenosis.

Neurosurgery was consulted and recommended computed tomography (CT) of the thoracic spine [Figure 3] with plans for possible surgical decompression and exploration the following day.
Magnetic resonance imaging with axial (a) and sagittal (b) views 1 month after hospital discharge showed mild improvement of disc herniation and stenosis. T5/6 disc herniation is decreased, but T4/5 disc remains unchanged.

One month repeat, MRI showed significant improvement of disc herniation and stenosis [Figure 4].
Magnetic resonance imaging with axial (a) and sagittal (b) views 6 months after hospital discharge showed complete resolution of epidural calcification and stenosis. The T4/5 and T5/6 discs still displayed calcification, but herniation had entirely resolved.

T4/5 and T5/6 discs still displayed some calcification, but herniation had completely resolved [Figure 5]. The patient remained symptom free at this time.
