Abstract
Objective To analyze the characteristics of osteoid osteoma on X-ray and CT imaging. Methods X-ray and CT imaging of 12 cases of osteoid osteoma proved by surgery and pathology were retrospectively analyzed and collected, including 8 males and 4 females. The X-ray and CT imaging manifestations of osteoid osteoma and their display capabilities of tumor niduses and changes around the tumor niduses were analyzed, and their characteristic imaging features were summarized. Results The imaging manifestations of osteoid osteoma revealed a circular or oval radiolucency(nidus) with different bone sclerosis around the nidus. The diameter ranged from 0.5cm to 1.5cm, with the average of 0.9cm. Among 12 cases, only 8 cases showed nidus on X-ray plain film, all 12 cases with CT scanning showed nidus. The detection rate of nidus was 66.7% (8/12) for X-ray plain film and 100% (12/12) for CT, respectively. Conclnsion The tumor nidus is the key to the diagnosis of osteoid osteoma, X -ray imaging of osteoid osteoma is quite typical and CT is a best modality for diagnosis of the diseasr.[Chinese Medical Equipment Journal,2012,33(4) ;78-79]关键词
