It is a relatively rare congenital tumor, often combined with other congenital malformations, such as spina bifida and spondylolisthesis. The tumor may be located inside or outside the dura or within the medulla. It accounts for about 1% of intravertebral canal tumors. Intraspinal lipoma grows slowly, and because it is more often located on the dorsal side of the spinal cord, numbness of limbs and sensory ataxia are common. When the tumor is too large and compresses the spinal cord, transverse spinal cord symptoms may appear. MRI examination shows high signal on T1WI (short T1), high signal on proton-weighted image but slightly lower than on TlWI, long T2WI (high signal); the tumor has very low signal or even no signal on lipid-suppressed image. Due to the presence of chemical shifts, high and low signal bands can often be seen along both edges of the tumor in the frequency encoding direction, respectively. Treatment: For epidural lipomas, total resection can be performed. When the tumor is located outside the subdural medulla and mostly adheres closely to the soft membrane of the spinal cord or spinal nerves, it should not be forcibly removed to avoid damaging the nerve tissue. Intramedullary lipomas, located in the submural spinal cord, can be carefully separated under the microscope and excised in pieces.
