Mesenchymal chondrosarcoma of right hypaxial muscles in a 37-year-old female with chronic cervical pain and bump in the neck. MRI shows a lobulated mass with high signal on axial T2WI (a) and heterogeneous enhancement pattern after contrast injection (black arrowheads, b). White arrowhead demonstrates the disappearance of the fat plane separating the mass and the neural arch. The yellow star shows the epicentre of the mass. Cervical radiograph (oblique view) shows posterior cervical fixation following laminectomy (c)
