Abstract
RÉSUMÉ
Cet article décrit le cas d’une femme de 40 ans opérée en Mai 2025 à l’Hôpital Général de Douala pour un syndrome du canal carpien droit. L’origine de la compression était une tumeur de Schwann (schwannome) du nerf médian. L’intervention chirurgicale a consisté en l’exérèse tumorale avec neurolyse du segment nerveux affecté. Les symptômes préopératoires (douleur, paresthésies et perte de sensibilité/trophisme) se sont améliorés post opératoirement, avec récupération fonctionnelle progressive de la main. Ce cas souligne l’importance du diagnostic différentiel des compression du nerf médian, le rôle d’une prise en charge multidisciplinaire et de la surveillance postopératoire dans les schwannomes nerveux.
ABSTRACT
This article describes the case of a 40-year-old woman who underwent surgery in May 2025 at Douala General Hospital for right carpal tunnel syndrome. The source of the compression was a Schwann cell tumor (schwannoma) of the median nerve. The surgical procedure consisted of tumor resection with neurolysis of the affected nerve segment. Preoperative symptoms (pain, paresthesia, and loss of sensation/trophism) improved postoperatively, with progressive functional recovery of the hand. This case highlights the importance of differential diagnosis for median nerve compression, the role of multidisciplinary management, and postoperative monitoring in nerve schwannomas.
