*Correspondance et tirés à part

Nous rapportons quatre observations de sciatique par bulle de gaz compressive isolée. Une telle éventualité est rare puisque seuls 21 cas sont mentionnés dans la littérature. Les signes cliniques ne diffèrent pas de ceux de la sciatique discale commune, et les radiographies simples sont souvent peu parlantes. Le diagnostic est alors scanographique, montrant une collection épidurale hypodense venant refouler la racine nerveuse.

Mots clés  : discopathie dégénérative ; gaz épidural ; sciatique ; vide discal.


We report four cases of sciatica caused by gas in the epidural space with no other abnormality. Only 21 similar cases have been reported. Clinical features are identical to those of common sciatica, and plain radiographs are often uninformative. Computed tomography shows a low-density epidural collection displacing the nerve root.

Mots clés  : degenerative disk disease ; epidural gas ; intradiscal vacuum phenomenon ; sciatica.
