The purpose of this study is to compare the surgical and imaging outcome in children who underwent brain tumour surgery with intention of complete tumour resection, prior to and following the start of intra-operative MRI (ioMRI) service. ⋯ Following the advent of ioMRI at our institution, the need for repeat resection within 6 months has been prevented in cases where ioMRI revealed unequivocal evidence of residual tumour.

We experienced a rare case of lipomyelomeningocele diagnosed at birth by magnetic resonance imaging which transformed the radiological appearance after 2 months into the transitional-type spinal lipoma with rapid increase in size of lipoma. Intraoperative findings revealed the presence of the dural sac extended dorsally outside the vertebral canal, which was characteristic of lipomyelomeningocele. Although there have been several reports showing that the size of spinal lipoma changed during development, there have been no reports which demonstrated alteration of radiological subtype with rapid increase of lipoma. Herein, we describe the first case of lumbosacral lipoma which changed radiological subtype from lipomyelomeningocele into transitional-type spinal lipoma.
