[Spontaneous spinal cord herniation: a little-known cause of Brown-Sequard syndrome. Report of two cases and review of the literature].
We report two cases of spinal cord herniation. The first one concerns a 28 year-old female who presented with an eighteen-month past history of spasticity of the right lower limb associated with somesthetic sensorial disturbances of the left side with a T4 level, related to a T3-T4 spinal cord herniation. The second case concerned a 58 year-old female with a past history of a left lower limb pyramidal syndrome associated with somesthetic and proprioceptive sensibilities disturbances of the right side with a T5 level related to a T4-T5 spinal cord herniation. Spinal cord herniation is an uncommon and underestimated cause of a progressive Brown-Sequard syndrome. The diagnosis is now easy on the MRI, showing a ventral attraction of the cord. The outcome is usually good, following the surgical reduction of the herniation.
