Summary:

Description
  • Radiopaedia case ID: 51394
  • Image ID: 28978020
  • Image stack position: 15/22
  • Plane projection: Sagittal
  • Aux modality: T2
  • Study description: MRI Lumbosacral
  • Study findings: Coronal T2- weighted images shows diffuse abnormal circumferential thickening of thecal sac with blooming artefact, concordant with dural calcifications seen on CT images. Axial T2-weighted images show displacement of the nerve roots of the cauda equina in the initial images. Abnormal thickening and clumping of the cauda equina with intrathecal hypointense signal abnormality seen at distal lumbar, consistent with sequelae of arachnoiditis. Well defined hyperintense lesion within L4 vertebra body in keeping with a vertebral hemangioma. Based on CT and MRI findings, features consistent with arachnoiditis ossificans.
  • Modality: MRI
  • System: Spine
  • Findings: Metal artefacts from posterior instrumentation traversing T12 and L2 lamina bilaterally fixing an old L1 vertebral fracture. Diffuse dense curvilinear calcifications are seen along the anterior spinal dura mater extending from L1 till L5 level. Multiple intrathecal calcifications suggestive of cauda equina ossifications. Some of the intrathecal calcifications follow the course of traversing nerve roots. Left intertrochanteric fracture with large surrounding subacute hematoma concordant with a recent history of fracture.
