Herniated lumbar disc L4 L5

Summary

[edit]
Description
Français : IRM DU RACHIS LOMBAIRE

Indication Lombosciatalgies gauches.

Technique Séquence en coupes sagittales T1 et T2 Dixon et une séquence 3D T2 en coupes axiales.

Résultat

  • Absence de tassement vertébral.
  • Pas de recul du mur postérieur.
  • Le cône médullaire se termine normalement en regard de T12-L1, de morphologie normale.
  • Le canal lombaire osseux est de dimensions normales.
  • Morphologie normale des articulaires postérieures.

Aux étages L1-L2, L2-L3 et L3-L4

  • Minime débord discal global sans saillie focale et sans conflit radiculaire.
  • Les foramens latéraux sont libres.

À l'étage L4-L5

  • Débord discal global avec saillie focale paramédiane gauche conflictuelle avec l'émergence apparente du fourreau dural de la racine L5 gauche.
  • Les foramens latéraux sont libres.

A l'étage L5-S1

  • Débord discal global prédominant en paramédian droit sans conflit radiculaire évident.
  • Les foramens latéraux sont libres.

Conclusion

On retient de cet examen la présence d'une hernie discale paramédiane gauche à l'étage L4-L5 conflictuelle avec l'émergence apparente du fourreau dural de la racine L5 gauche
English: LUMBAR SPINE MRI

Indication Left lower back pain.

Technique Sequence in T1 and T2 Dixon sagittal slices and a 3D T2 sequence in axial slices.

Result

  • No vertebral compression.
  • No posterior wall recoil.
  • Medullary cone terminates normally opposite T12-L1, with normal morphology.
  • Normal lumbar canal dimensions.
  • Normal morphology of posterior joints.

At L1-L2, L2-L3 and L3-L4 levels

  • Minimal disc protrusion overall, with no focal protrusion or root impingement.
  • The lateral foramen are free.

At L4-L5

  • Global disc overhang with left paramedian focal protrusion in conflict with the emergence of the dural sheath of the left L5 root.
  • The lateral foramen are free.

At L5-S1'

  • Global disc overhang predominantly right paramedian, with no obvious radicular impingement.
  • The lateral foramen are free.

Conclusion

This examination revealed a herniated left paramedian disc in the L4-L5 level, with apparent emergence of the dural sheath of the left L5 root
