Abstract

Karpal tünel sendromu (KTS), medyan sinirin karpal tünel içerisinde sıkışmasıyla ortaya çıkan ve en sık görülen tuzak nöropatisidir. Çoğunlukla idyopatik olmakla birlikte sinire bası yapan birçok patoloji ve anatomik varyasyonlar KTS'ye neden olabilir. Bu yazıda, patent medyan arter ve bifid medyan sinir gibi KTS etyolojisinde yer alan iki nadir anatomik varyasyonu olan KTS olgusunun ultrasonografi ve magnetik rezonans görüntüleri sunuldu. Anahtar kelimeler: Karpal tünel sendromu, Medyan nöropati, Medyan sinir.

Keywords

Karpal tünel sendromu, Medyan nöropati, Medyan sinir.

Patent Median Artery and Bifid Median Nerve in Carpal Tunnel Syndrome: A Case Report

Abstract

Carpal tunnel syndrome is the most frequent entrapment neuropathy which is observed due to compression of the median nerve at the level of carpal tunnel. Most of the reported carpal tunnel syndrome disease is idiopathic; however pathologies like anatomic variations can be identified. We report the imaging findings of a case with carpal tunnel syndrome due to association of two infrequent anatomic variations: patent median artery and bifid median nerve. Key words: Carpal tunnel syndrome, Median neuropathy, Median nerve.

Keywords

Carpal tunnel syndrome, Median neuropathy, Median nerve.
