Leiomyoma in a 60-year-old male with non-mechanical cervical pain. MRI scan shows a lobulated mass in left epaxial muscles (white arrowheads) with low signal intensity on T1WI (a) and enhancement on axial (b) and sagittal (c) contrast-enhanced fat-saturated T1WI. Several features are suggestive of vertebral bone invasion: disappearance of the fat plane separating the mass and the neural arch associated with a low signal of medullary bone of the articular process on T1WI (white arrow), disappearance of cortical bone and enhancement of medullary bone (black arrowheads) on contrast-enhanced T1WI. The yellow star shows the epicentre of the mass
