目的:分析骨样骨瘤的X线及CT表现,探讨X线、CT,尤其是多排CT的诊断价值。方法:回顾性分析经手术病理和临床证实的骨样骨瘤24例,24例均行X线检查,同时行CT扫描18例;股骨10例,胫骨7例,肱骨3例,颈椎2例,髂骨2例;分析比较X线和CT对瘤巢及瘤巢周围骨质改变的显示能力。结果:X线和CT检查分别有19例和18例表现为一卵圆形或圆形瘤巢,直径<2 cm;管状骨的骨样骨瘤与骨干相邻处骨皮质见骨质硬化;X线和CT的诊断准确率分别为79.2%和100%。结论:骨样骨瘤有特征性X线表现,结合典型的夜间疼痛为主的临床症状一般可明确诊断;CT对瘤巢定位更准确,恰当的CT后处理技术对提高本病诊断准确率有重要价值。
Objective: To analyze the X-ray and CT findings of osteoid osteoma and explore the diagnostic value of X-ray, CT, especially multi-slice CT. Methods: Twenty-four patients with osteoid osteoma confirmed by operation, pathology and clinical examination were retrospectively analyzed. Twenty-four patients underwent X-ray examination and CT scan at the same time. Eighteen femurs, ten femurs, seven tibias, three humerus, two cervical vertebrae, Iliac in 2 cases; analysis and comparison of X-ray and CT on the nests and around the neoplasm of the display of bone changes. Results: In 19 cases and 18 cases of X-ray and CT examination, oval or round tumor nests were found with a diameter of less than 2 cm. Osseous sclerosis was found in the cortical bone of the osteoid osteoma of the tubular bone adjacent to the backbone. X-ray and CT diagnostic accuracy rates were 79.2% and 100%. Conclusions: Osteoid osteoma has the characteristic X-ray manifestations. The clinical symptoms associated with typical nocturnal pain can be generally diagnosed. CT is more accurate to locate tumor nests. Appropriate CT post-processing techniques can improve the diagnostic accuracy of this disease. Important value.
