(a) Radiograph of cervical spine in anteroposterior and (b) Lateral projection. There is ovoid calcification in C2-3 intervertebral disc space (arrows)

C2-3 level [Figure 1]. Computed tomography (CT) of the spine confirmed the presence of IVDC and also showed calcification in the adjoining anterior epidural space.
Computed tomography scan of cervical spine. (a) Axial and (b, c) Sagittal reformatted images. There is calcification of the intervertebral disc C2-3 with associated calcification in adjoining anterior epidural space (arrows). The adjoining vertebral end plates are normal (curved arrows in b)

There was no associated erosion of adjoining vertebral end plates and no pre- or paravertebral soft tissue component [Figure 2].
Magnetic Resonance Imaging (MRI) of cervical spine: (a) Sagittal T1W and (b) T2W images. The intervertebral disc C2-3 shows abnormal hypointense signal with posterior herniation and compression of adjoining cervical spinal cord. Normal signal intensity is demonstrated by spinal cord. The cervical vertebrae C2 and C3 show normal morphology and signal intensity

T1 and T2 hypointensity, consistent with calcification. There was associated significant posterior protrusion of the calcified disc material into the anterior epidural space with compression of underlying cervical spinal cord; however, no signal changes were seen within the cord [Figure 3].
Follow-up Magnetic Resonance Imaging at 3 months. Sagittal T2W image demonstrates near-complete resolution of the pathology with normal spinal cord

Follow-up MRI done after 3 months [Figure 4] demonstrated near-complete resolution of the disc calcification and posterior protrusion.
