Magnetic resonance imaging: lumbosacral lipoma
Surgical Neurology
|October 1, 1987
Summary
Magnetic resonance imaging (MRI) effectively visualizes lumbosacral lipomas, revealing key anatomical details. This suggests MRI may replace myelography and CT cisternography for diagnosing these spinal cord conditions.
Area of Science:
- Medical Imaging
- Neurology
- Radiology
Background:
- Lumbosacral lipomas are congenital spinal anomalies.
- Accurate imaging is crucial for diagnosis and surgical planning.
Purpose of the Study:
- To assess the clinical efficacy of magnetic resonance imaging (MRI) for lumbosacral lipomas.
- To compare MRI with other diagnostic modalities.
Main Methods:
- Review of MRI scans from nine patients with lumbosacral lipomas.
- Utilized T1- and T2-weighted spin echo sequences on a 0.5-T MRI system.
Main Results:
- MRI clearly depicted the conus medullaris, lipoma, lipoma-cord interface, subarachnoid space, and hydromyelia.
- Nerve rootlets were less distinctly visualized.
- Demonstrated the potential to discontinue myelography and metrizamide CT cisternography.
Conclusions:
- MRI is a highly effective modality for imaging lumbosacral lipomas.
- Plain spine films, CT scans, and MRI are the preferred diagnostic tools.
- MRI offers superior visualization of critical structures compared to traditional methods.
