It is during the probable myelination phase that the majority of symptoms appear. Analysis of the FA shows that the presence of a lipoma seems to have an effect on the myelination of the conus medullaris. Tractography of the conus medullaris in a very young pediatric population (0–8 years old) with a spinal lipoma is possible, reproductive, and allows visualization of the spinal cord within the dysraphism. Destruction or disorganization of fibers and any passing inside the lipomas was not observed. The conus medullaris was deformed and shifted. The tractography obtained in each case was coherent with morphologic sequences and reproducible.

However, no significant differences in the mean values of FA, RD, and MD between the level of the lipoma and the level above were noted. We found a significant difference in the FA ( p = 0.024) between two age groups ( 24 months old). The diffusion parameters have been calculated by Osirix DTImap plugin. Tractography reconstruction of the conus medullaris of 12 patients were obtained using the MedINRIA software. Twelve patients (0–8 years) related to spinal lipomas treated between May 2017 and March 2018 were included. In a preliminary work, spinal lipoma was chosen for analyzing the micro-architecture parameters and fiber morphology of the spinal cord by DTI with tractography. One of the major challenges in dysraphism is to know the morphologic organization of the spinal cord.

Diffusion tensor imaging (DTI) allows studying the micro and macro architecture.
