Diagnosis: Compression of brainClinical question: Please evaluate for syrinx or cord tetheringSigns and Symptoms: Known Chiari, dizziness MRI thoracic spine:The thoracic vertebral bodies are appropriate in the overall alignment and height. The thoracic spinal cord has normal signal characteristics and overall morphology. There is no compromise of thoracic spinal canal or exiting nerve roots. The thoracic spinal cord ends at approximately L1.There is a 12 mm T1 and T2 hyperintense focus present within the T10 vertebral body along its left posterior and inferior aspect. T1 signal suppresses on the inversion recovery images. There are Schmorl's nodes present at the T11-T12 and T12-L1 disc spaces.There is a left lateral recess disc protrusion at the T10-T11 without significant compromise to spinal canal or exiting nerve roots. It mildly narrows the left neural foramen at this level and impresses on the thecal sac at the left lateral recess.
1.There are mild degenerative changes present in the lower thoracic spine. There is a small disc protrusion at T10-T11 without significant compromise to the spinal canal or exiting nerve roots2.There is no evidence for tethered cord.3.There is no evidence for syrinx in the thoracic spinal cord.
