Midline low back pain without sciatica MRI thoracic spine:At T8-T9 there is a T1 and T2 hypointense lesion present within the left anterior aspect of the spinal canal measuring 11 x 7 mm axial dimensions and 18 x 9 mm sagittal dimensions. It tracks behind the adjacent vertebral bodies. It extends towards the left T8-9 neural foramen and abuts the left pedicle of T9. This lesion mildly displaces the spinal cord towards the right.The T8-T9 disc is mildly desiccated and there is mild loss of disc space height at T8-T9. There is some loss of disc space height at T6-T7.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. Lumbar spine:Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact.At L5-S1 there is no significant compromise to spinal canal or neural foramina. There is a broad-based central disc protrusion present at L5-S1 which impresses on the ventral aspect of the thecal sac. It does extend into the inferior aspects of the neural foramina. It abuts the nerve roots at the right lateral recess but does not compress them. It extends across the midline and minimally abuts the nerve roots at the left lateral recess. The disc protrusion itself this contains some high signal material.At L4-5 there is no significant compromise to spinal canal or neural foramina.At L3-4 there is no significant compromise to spinal canal or neural foramina.At L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
1.There is a lesion present along the left lateral recess at T8-T9 which appears represent a partially calcified mass. It is most likely discogenic in origin. A CT of the thoracic spine may help further evaluate it if information on calcification is needed.2.There is a small central disc protrusion eccentric to the right present at L5-S1 without significant compromise spinal canal or neural foramina. It abuts the nerve roots at the right lateral recess.
