Bony retropulsion along with canal stenosis is also obvious at C6 level [Figure 1].

Lesion appears as low signal intensity mass on both T1- and T2-weighted MRI [Figure 2].

Based on the clinical scenario and imaging findings, decision was made to perform C6 corpectomy with C5-C6 and C6-C7 discectomy [Figure 3].
Degenerated fibrocartilaginous tissue and a giant cell-rich lesion composed of large multinucleated cells admixed with regular and uniform stromal cells with foci of new bone formation with multiple areas of necrosis and hemorrhage were noted as microscopic features
