Overview
MRI may be helpful in the diagnosis of lipoma. Findings on an MRI suggestive of lipoma include a well-defined lesion with intensity similar to that of subcutaneous fat.
MRI
- MRI may be helpful in the diagnosis of lipoma. Findings on an MRI suggestive of lipoma include a well-defined lesion with intensity similar to that of subcutaneous fat.[1][2]
- The lesion may have thin septations. The internal septa may have low signal intensity on TI- and T2-weighted images.
Examples of MRI Findings for Lipoma
- Spinal intramedullary lipoma appears as a well-defined, homogeneous hyperintense signal on both T1- and T2-weighted images.
