55-year-old woman with history of parotid carcinoma, now with severe back pain. There are multiple enhancing, T2 hyperintense, and T1 hypointense lesions within the vertebral bodies of T1, T2, T6, T8, T10, and T12 along with the posterior elements of T4 and T9. There is no loss of vertebral body height and the thoracic spine is in normal alignment. Of these lesions, a T9 left laminar lesion (901/17) erodes through the cortex into the surrounding soft tissues and indents the posterior thecal sac. The spinal cord is of normal caliber and signal and there is no spinal canal or neural foraminal compromise. The intervertebral disk heights are well-maintained. A right pleural effusion, pleural based nodule, and bilateral nodular adrenal thickening are noted, better characterized on recent CT.LUMBAR SPINE
1.Multiple enhancing osseous metastases throughout the thoracic and lumbar spine. Specifically, there is cortical destruction of the left T9 lamina with slight tumor extension into the paraspinal musculature and minimally compression of the thecal sac.2.Multilevel lumbar spine degenerative changes without significant spinal canal or neural foraminal stenosis.
