Normal vertebral alignment. There is a 20 mm x 37 mm x 35 mm lytic expansile lesion centred within the right posterior elements of T11 thoracic vertebra extending into the spinous and right transverse process. There is marked cortical thinning, with cortical breaches, but no evidence of calcification or internal matrix. Zone of transition appears narrow.
As a result of the expansion, there is marked narrowing of the spinal canal at this level, as well as narrowing of the T11-T12 exit foramen on the right. There is also a small lytic lesion in the right posterosuperior pedicle of T12 with cortical thinning against the spinal canal; this abuts & is most probably extension of the T11 tumour.
Lytic expansile lesion centred within the posterior elements of T11 on the right causing significant spinal canal stenosis and likely cord compression.
