Magnetic resonance imaging: lumbosacral lipoma.
To evaluate the clinical efficacy of magnetic resonance imaging (MRI) of lumbosacral lipomas, the magnetic resonance images of nine patients were reviewed. T1- and T2-weighted spin echo sequences were used with a 0.5-T magnetic resonance system. The tethered or low-positioned conus medullaris, the lipoma itself, the lipoma--cord interface, the subarachnoid space, and hydromyelia were clearly disclosed. The nerve rootlets were not as clear. These results indicate the possible discontinuance of myelography and metrizamide computed tomography (CT) cisternography for such imaging. The diagnostic modalities of choice for lumbosacral lipoma imaging are plain spine films, plain CT scan, and MRI.
