Pençe El Deformitesi ile Birlikte Görülen Chiari Tip 1 Deformitesi: Nadir Bir Olgu Sunumu

Chiari malformasyonu (CM) santral sinir sisteminin en sık görülen malformasyonlarından birisidir. Bu durum siringomiyeli, hidrosefali ve ilişkili patolojiler ile birlikte görülebilir. Bu yazıda nadir görülen bir CM klinik bulgusu anlatılmaktadır. Daha önce ulnar sinir hasarı nedeniyle yanlış tanı konulmuş ve transpozisyon cerrahisi uygulanmış pençe el deformitesi olan 45 yaşında erkek hasta polikliniğimize pençe el deformitesi ile başvurdu. Yapılan elektronöromiyografi (ENMG) sonrasında ulnar sinirde herhangi bir iletim problemi saptanmadı. Yapılan değerlendirmede hasta sirings kavitesi olan CM tip-1 tespit edildi. Hasta ileri tedavi amacıyla beyin cerrahisi kliniğine konsulte edildi. CM tip-1 sıklıkla siringomiyeli ile birlikte görülür. Pençe el sıklıkla travmatik ya da tumor ilişkili sirinks kavitesi ile ilişkilidir ancak CM tip-1 ile birlikteliği nadirdir. Bu gibi hastalarda farklı sebeplerinde olabileceği akılda tutulmalıdır.

Chiari I Malformation Presenting with Claw Hand Deformity: An Unusual Case Report

Chiari malformation (CM) is one of the most common malformations of central nervous system. It may be seen with syringomyelia, hydrocephalia and associated pathologies. We described an uncommon clinical presentation of CM in this paper. We report a case of 45 years old male patient consulted to our outpatient clinic with claw hand deformity who had misdiagnosed as ulnar entrapment neuropathy and undergone transposition surgery. We performed electroneuromyography (ENMG) to the patient and revealed normal conduction in ulnar nerve. We focused on the other causes of the deformity and found CM type-I with a syrinx cavity. We consulted the patient to neurosurgery clinic of our center for further treatment. CMI is often associated with syringomyelia. Claw hand is oftenly associated with traumatic or tumor related syrinx cavity but association with CMI is very unusual. We recommend the evaluation of such patients more carefully focusig on different causes.
