 The evaluation for leptomeningeal metastatic disease is nondiagnostic given the lack of intravenous contrast.Cervical spine:Artifact limits evaluation of the lower cervical spine axial T2 sequence. There is straightening of the normal cervical lordosis. The vertebral body heights are grossly preserved. The bone marrow demonstrates heterogeneous marrow signal. There is no evidence of acute fracture. Mild degenerative spondylosis affects the cervical spine. A Schmorl's node is noted along the inferior endplate of C4. Disc osteophyte complexes are noted at C3-4 through C6-7 without significant spinal canal stenosis or neural foraminal narrowing. The cervical cord is normal in caliber and signal. The thyroid is incompletely assessed only on the sagittal images and appears heterogeneous as well as slightly prominent.Thoracic spine:There is signal dropout limiting evaluation of the STIR sequence cranially. The axial T2 images of the lower thoracic spine are nondiagnostic. Alignment of the thoracic spine is within normal limits. Vertebral body height is grossly preserved. The bone marrow signal is mildly heterogeneous. No evidence of acute fracture. Mild degenerative spondylosis affects the thoracic spine. Schmorl's nodes are present at the T8 and T9 superior endplates and T10 inferior endplate. No significant spinal canal stenosis or neural foraminal narrowing. The spinal cord is normal in caliber and signal.Lumbar spine:The axial T1, T2, and sagittal STIR sequences were not performed. Alignment of the lumbar spine is anatomic. The vertebral body heights are preserved. The bone marrow signal is within normal limits. Minimal disc protrusions affect the lower lumbar spine. There is no significant spinal canal stenosis or neural foraminal narrowing at any level. The visualized distal cord and conus medullaris are normal in caliber and signal. The cord terminates at L2-3.
1. Nondiagnostic evaluation for leptomeningeal metastatic disease given the lack of intravenous contrast.2. No evidence of abnormal cord signal or spinal canal stenosis.3. Incompletely assessed, but mildly prominent and possibly heterogeneous thyroid gland. Please correlate with physical exam.
