Findings
- Transversely-oriented fracture through the S2 vertebral body with mild ventral surface cortical impaction and kyphosis
- Incompletely imaged vertically-oriented fractures involving the bilateral sacral ala with surrounding STIR signal hyperintensity
- T2/STIR signal hyperintensity in the adjacent paraspinal musculature extending superiorly to the level of L2
- Mild multilevel degenerative changes with multilevel broad-based disc bulges, facet hypertrophy, and ligamentum flavum thickening contributing to mild spinal canal stenosis, moderate crowding of the bilateral subarticular zones, and mild bilateral neural foraminal stenosis at L4-L5
- Normal position and signal of the conus
- Normal marrow signal
- Normal alignment
Diagnosis
Sacral insufficiency fractures
Sample Report
Acute/subacute sacral insufficiency fractures involving the bilateral sacral ala and involving the S2 vertebral body with mild ventral cortical impacting and kyphosis.
No abnormal marrow signal in the lumbar spine to suggest an acute fracture, though CT should be considered for further evaluation if there is clinical concern.
T2/STIR signal hyperintensity in the adjacent paraspinal musculature extending superiorly to the level of L2, likely relating to muscular strain.
Mild multilevel degenerative changes with multilevel broad-based disc bulges, facet hypertrophy, and ligamentum flavum thickening contributing to mild spinal canal stenosis, moderate crowding of the bilateral subarticular zones, and mild bilateral neural foraminal stenosis at L4-L5.
