Peroneal Nerve Palsy due to Synovial Cyst of Proximal Tibiofibular Joint

Synovial cysts are benign soft-tissue tumors that arise from synovial joints or tendon sheaths. Synovial cyst of proximal tibiofibular joint is a very rare condition, which is included in non-traumatic causes of peroneal nerve palsy. This article presents clinical, and radiological findings of peroneal nerve palsy in a 50-year-old male patient admitted with sudden drop foot. Based on the clinical examination, electroneuromyography data, magnetic rezonans image the compression of nerve by synovial cyst was confirmed. Peroneal nerve palsy was completely improved after surgical resection of synovial cyst and physical theraphy and rehabilitation. In conclusion, synovial cysts of proximal tibiofibular joint causing peroneal nerve palsy should be remembered as a possible differential diagnosis for patient with drop foot.

Proksimal Tibiofibular Eklemin Sinovyal Kistine Bağlı Gelişen Peroneal Sinir Felci

Sinovyal kistler, sinovyal eklemlerden veya tendon kılıflarından köken alan iyi huylu yumuşak doku tümörlerindendir. Proksimal tibiofibular eklemin sinovyal kisti, peroneal sinir felcinin nadir görülen travma dışı nedenleri arasında yer almaktadır. Bu yazıda aniden düşük ayak gelişen 50 yaşındaki erkek hastada proksimal tibiofibuler eklemin sinovyal kistine bağlı peroneal sinir felcinin klinik ve radyolojik bulguları sunulmuştur. Temel olarak, klinik muayene, elektronöromiyografik inceleme magnetik rezonans görüntüleme ile sinovyal kistin baskıya neden olduğu ortaya konmuştur. Sinovyal kistin cerrahi çıkarımı ve fizik tedavi ve rehabilitasyon uygulamaları sonrası olgunun klinik bulguları geriledi. Sonuç olarak düşük ayak gelişen olgularda proksimal tibiofibular eklemin sinovyal kistine bağlı peroneal sinir felci gelişebileceği akılda bulundurulmalıdır.
