ABSTRACT
Objective To analyze MRI features of intraspinal ganglioneuroma,in order to improve the ability of preoperative diagnosis.Methods MRI data of 9 patients of intraspinal ganglioneuroma confirmed pathologically were analyzed retrospectively.The location,morphology,size,signal intensity and degree of enhancement of these lesions were observed.Results Totally 9 lesions were enrolled.Four lesions occurred in the cervical spine,2 in the thoracic spine and 3 in the lumbosacral spine.Seven lesions were dumbbell shaped,involving both intra and extra-canalicular,and 2 lesions present as nodules in the foramen.All the lesions demonstrated homogeneous or heterogeneous high signal on T2WI,with only 1 lesion showed cystic change and necrosis.Contrast-enhanced scanning was performed in 8 lesions,and marked enhancement was shown in 3 lesions,mild-moderate enhancement in 5 lesions.Strand-shaped enhancement took place in 4 lesions.The intervertebral foramina of all the lesions were enlarged,but without bone destruction.Conclusion Intraspinal ganglioneuroma has some characteristics on MRI,which may be helpful to accurate preoperative diagnosis.
