Kübital Tünel Sendromuna Neden Olan Ulnar Schwannom: Olgu Sunumu

Ulnar sinirin anatomik seyri sırasında basıya uğradığı en sık yer dirsek düzeyindeki kübital olukdur. Kübital tünel sendromu etyolojisinde en sık kronik bası ve travma yer almaktadır. Sinir kılıfı tümörleri de etyolojide yer almaktadır. Schwannomlar schwan hücrelerinden gelişen benign sinir kılıfı tümörleridir. Olgumuz 45 yaşında bayan hasta olup sağ el 4. ve 5. parmaklarda meydana gelen uyuşma şikayeti ile polikliniğimize başvurdu. Fizik muayenede sağ dirsek medial epikondil komşuluğunda mobil yaklaşık olarak 3 çapında kitlesel lezyon saptandı. Cerrahiye alınarak kitle tamamen çıkarıldı. Histopatolojik incelemesi schwannom olarak geldi. Periferik schwannomlar bazen tuzak nöropatilere neden olabilir. Cerrahi sırasında dikkatli diseksiyon hastaya nöral hasar vermemizi önleyecektir.

Ulnar Schwannoma Causing Cubital Tunnel Syndrome: A Case Report

The most common place of compression during the anatomical course of the ulnar nerve is the cubital groove at the elbow level. Chronic compression and trauma are the most common etiology of cubital tunnel. In addition, nerve sheath tumors are also found. Schwannomas are benign nerve sheath tumors developing from schwann cells. In our case is a 45 year-old female patient presented to our neurosurgery outpatient clinic with numbness in finger 4th and 5th of right hand. Physical examination revealed a 3 cm-diameter, mobile mass lesion located in the medial epicondyle of the right elbow. The patient underwent surgery. Under general anaesthesia, the tumor was completely resected. The histopathological examination of the lesion was reported as Schwannoma. Peripheral schwannomas sometimes can cause entrapment neuropathies. Careful dissection during surgery will prevent us from causing neural damage.
