Conjoined lumbosacral nerve roots

Abstract

Lumbosacral nerve root anomalies are a rare group of congenital anatomical anomalies. Various types of anomalies of the lumbosacral nerve roots have been documented in the available international literature. Tthese anomalies may consist of a bifid, conjoined structure, of a transverse course or of a characteristic anastomized appearance. Firstly described as an incidental finding during autopsies or surgical procedures performed for lumbar disk herniations and often asymptomatic, lumbosacral nerve root anomalies have been more frequently described in the last years due to the advances made in radiological diagnosis.

Conjoined lumbosacral nerve roots

Abstract

Konjenital anatomik anomaliler arasında lumbosakral sinir kökü anomalileri nadir görülen bir gruptur. Literatür ince-lendiğinde çok farklı lumbosakral sinir kökü anomalilerinin raporlandığı gözlenebilmektedir. Bu anomalilerin alt grupla-rı kabaca bifid, birleşik yapı, transvers yönde veya anostomozlaşmış yapıda olmaları şeklinde sınıflandırılmaktadır. Görüntüleme yöntemlerinin gelişmesinden önce bu yapılar otopsi çalışmaları ve lumbar disk herniasyonuna yönelik cerrahi girişimler sırasında insidental olarak gözlenmiştir ve çoğunlukla asemptomatikirler.

Keywords

• Lumbosakral sinir kökü, anomali, birleşik sinir kökleri.
