Abstract
Objective To investigate and analyze the diagnostic imaging features of patients with far lateral lumbar disc herniation (FLLDH) by CT and MRI.Methods 38 patients with FLLDH were diagnosed,and its radiology imaging diagnosis and clinical characteristics were analyzed.The main positive results of intervertebral disc herniation segment by CT and MRI scanning and its imaging features were observed.Results The positive of CT scans was 94.74％ (36/38),MRI scans was 100％ (38/38),the difference was not statistically significant (x2 =2.89,P ＞0.05) ;disc segments were mainly in L3-4 and L4-5 segments respectively,MRI scans were 34.21％ (13/38) and 39.47％ (15/38),CT scans were 3 1.58％ (12/38) and 39.47％ (15/38) ;22 cases with hummocky,8 cases with semicircular,irregular triangular shape and 3 cases respectively ;4 cases with foramen medial,18 cases with lateral foramen,14 cases of mixed type;prominence of ＜ 3 mm was 13 cases,20 cases with 4 to 7 mm,8 cases with more than 7mm.Conclusion CT and MRI examination can accurately diagnose FLLDH and judge its location,extent and clinical timely treatment has important clinical application value.
