上期试题：关于骨软骨瘤的叙述，不正确的是D A．又称骨软骨性外生疣 B．多见于儿童 C．好发于四肢长骨的干骺附近，特别是股骨下端、胫骨上端及肱骨上端 D．生长缓慢，但症状多明显 E．X线片显示有正常骨组织的疣状肿物，界限清楚 脊柱结核易发生于儿童和青年，发病部位以腰椎多见，根据部位可分为椎体结核和附件结核，前者多见，椎体结核又可分为中心型、边缘型和韧带下型。 Risk prone on spinal tuberculosis in children and youth, in the lumbar spine, according to the parts can be divided into the vertebral tuberculosis tuberculosis and attachment, the former see more, vertebral tuberculosis and can be divided into the center, under the borderline and ligament. X线表现： 1、椎体结核中心型X线主要表现为相邻多个椎体骨质破坏，塌陷，可见小死骨形成，椎间隙狭窄，脊柱后突畸形，椎旁冷脓肿形成，其内常见钙化。边缘型主要表现为椎体前缘或上、下缘骨质破坏，常累及两个椎体，相应椎间隙变窄，椎旁冷脓肿形成。韧带下型主要表现为开始可仅有椎旁冷脓肿，逐渐出现椎体边缘骨质破坏，最后可出现椎体骨质破坏和椎间隙变窄。 1、vertebral tuberculosis center X line mainly for multiple vertebral body bone destruction, adjacent to collapse, a smaller dead bone formation, narrow intervertebral disc, spinal deformity, after vertebral side cold abscess formation, its common calcification. The borderline is characterized by the fracture of the anterior margin of the vertebra, the fracture of the lower margin, the lower margin of the vertebral body, and the narrowing of the intervertebral disk, and the formation of the laminar abscess. Ligament under type main show is beginning but only job by cold abscess, edge vertebral body bone destruction began to emerge, finally can appear narrow vertebral body bone destruction and intervertebral disc. 2、附件结核表现为椎弓的骨质破坏和周围的冷脓肿形成，椎体和椎间隙可无明显异常改变。 2、Appendix tuberculosis is characterized by bone damage of vertebral arch and cold abscess in the surrounding area, and there is no significant difference between vertebral and vertebral space. CT表现： CT更能清晰的显示骨质破坏，特别是较小和较隐蔽的破坏，可帮助了解脓肿位置及大小，与周围大血管、组织器官的关系，可显示椎管内受累的情况。 CT can clearly display bone destruction, especially the destruction of the smaller and more concealed, can help to understand the position and size abscess, and a larger blood vessels, the relationship between tissues and organs, and can be displayed on the involvement of the situation. 胸椎椎体骨质破坏并椎旁脓肿形成 MR表现： 脊柱结核的椎体信号改变，大多数T1WI呈现均匀的较低信号，少数病灶呈现混杂低信号，T2WI多呈现混杂高信号；增强扫描以不均匀强化常见。受累椎间盘T1WI多呈现低信号，T2WI常为不均匀混杂高信号。可清晰的显示脊柱结核沿前纵韧带下蔓延的特点。椎旁软组织包括脓肿和肉芽肿，T1WI呈现低信号或等信号；T2WI多呈现混杂高信号。脓肿壁薄且常有明显强化。 The vertebral signals of the spinal tubercle were altered, and most of the T1WI showed a relatively low signal, a small number of lesions were mixed with low signals, and T2WI was a mixed signal. Enhanced scanning is common with uneven reinforcement. A low signal is shown in T1WI, and T2WI is often a mixed signal. Clearly, the characteristics of the spread of the spinal tubercle in the anterior longitudinal ligament are clearly shown. The soft tissues in the vertebra include abscesses and granulomas, and T1WI shows low signals or signals; T2WI shows mixed signals. The abscesses are thin and often visibly reinforced. 本期试题：脊柱结核最常发生的部位是？ A．横突结核 B．椎弓结核 C．颈椎结核 D．胸椎结核 E．腰椎结核
