多层螺旋CT鉴别诊断脊柱旁肿瘤的临床应用价值

目的：探讨多层螺旋CT扫描在鉴别脊柱旁肿瘤中的作用。方法回顾性分析我院收治的33例脊柱旁肿瘤患者。经术后病理证实，神经源性肿瘤30例，孤立性纤维瘤2例，非霍奇金氏淋巴瘤1例。结果对比术前患者的常规CT图像、灌注增强CT图像。可以发现在所有神经源性肿瘤中呈良性表现者29例，包括17例神经鞘瘤，8例神经纤维瘤，4例节细胞瘤。常规CT显示为圆形或类圆形软组织影，密度略低于肌肉组织影，个别患者可见有散在坏死区，极少可出现钙化灶。其中恶性表现者1例，为神经鞘瘤。在常规CT显像上可见密度不均匀的软组织影侵蚀椎体造成骨质破坏。行灌注增强CT扫描后，结果呈环形、均匀、不均匀、无强化型、分隔样等多种强化类型。结论脊柱旁肿瘤中以神经源性肿瘤为主，明确后纵隔各种神经源性肿瘤的CT以及增强CT图像特征，在临床上鉴别脊柱旁肿块中有着重要意义。

Clinical value of multislice spiral CT in the differential diagnosis of paraspinal tumors

Objective To explore the role of multi-slice spiral CT scan faces in identifying paraspinal tumors. Methods A retrospective analysis of 33 patients admitted to our hospital who had paraspinal tumor. It had been confirmed that neurogenic tumors in 30 cases, 2 cases of solitary fibrous tumors and 1 case of non-Hodgkin＆#39;s lymphoma postoperative pathological. Results Compared with the patient＆#39;s routine preoperative CT image and enhanced CT perfusion images, it can be found benign manifestations can be found 29 cases, including 17 cases of schwannoma in all neurogenic tumors, eight cases of neurofibroma, four cases of ganglion cell tumors. Conventional CT appear as round or oval soft tissue, muscle tissue density slightly lower shadow, and individual patients were seen scattered in the necrotic area, which may form calcification. There was one case of malignant manifestations, schwannoma. It was visible on conventional CT imaging soft tissue density uneven erosion caused by vertebral bone destruction. Patients after partial perfusion CT scan, the results showed a circular, uniform, non-uniform, non-reinforced, strengthened and many other types of separate samples. Conclusion Neurogenic tumors is a primary part in paraspinal tumors. It is of great significance to make sure posterior mediastinal neurogenic tumors of various CT and contrast-enhanced CT image characteristics for the identifi-cation of the clinical side mediastinal mass in the spine.
