B型超声诊断腰椎TB脓肿及分型

B-Mode Ultrasound Diagnosis and Classification of Spinal TB Abscess

本文报告了27例腰椎TB合并椎旁脓肿的患者,早期TB的超声显示明显不及传统的X线,但对发展到一定程度超声是可以显示的,尤其当椎体遭到破坏形成椎旁或流注脓肿时,超声探查远优于传统的X线,并且二维超声可以对脓肿进行介入治疗,可随时观察治疗效果,从超声角度上分为两型:①包裹型;②窦道型。包裹型超声特点为一侧或两侧椎旁可探及无回声暗区,无相对完整的包膜,后方效应无明显增强,这与脓液是否完全液化程度有关,且与椎旁无回声暗区有相通的无回声暗带,向下追踪扫查可在髂窝及股三角处观察到流注的脓腔,所以超声在软组织与液注占位的分辨上优于X线平片。

This paper reports 27 cases of lumbar paraspinal abscess combined TB patients, early TB of ultrasound showed significantly less than traditional X -ray, but to a certain extent on the development of ultrasound can show, especially when the formation of paraspinal vertebral destruction or stream note abscess, the ultrasound probe is far superior to conventional X -ray, dimensional ultrasound and interventional treatment of abscesses can be readily observed treatment effects, from the perspective of ultrasound is divided into two types： CD package type, （2） sinus type. Package type is characterized by one or both sides ultrasound could be detected and no echo paravertebral dark areas, no relative intact membrane, the rear effects without significantly enhanced, this is completely liquefied pus degree, and with the paravertebral dark echo anechoic area interlinked dark band, scanning can be tracked down to the iliac fossa and femoral triangle streamer observed at the abscess, so ultrasound in soft tissue mass with fluid injection is superior resolution X-ray film.
