A case of osteoid osteoma (OO) in the mandible of 26-year-old female is presented. Her main complaint was intermittent pain during a 3 year period. The panoramic radiograph of the mandible showed diffuse sclerosis including an ill-defined circular radiopacity in the molar region. Computed tomography (CT) revealed an osseous lesion of 10 mm diameter that was located in the cortical bone of the mandible. Bone scintigraphy showed a localized region of high uptake of 99mTc HMDP. The lesion was diagnosed as an OO by histopathological examination of the surgical specimen and CT findings. Since radiological appearance has very significant meaning in the differentiation of an OO from other bone forming tumors, CT is the method of choice when the main symptom is pain and the conventional radiography was not informative.
本文报告一例26岁女性下颌骨骨样骨瘤（OO）病例。她的主要诉求是3年来间歇性疼痛。下颌骨全景X线片显示弥漫性硬化，包括磨牙区一个边界不清的圆形不透光区。计算机断层扫描（CT）显示一个直径10 mm的骨病变，位于下颌骨皮质骨。骨闪烁显像显示99mTc HMDP高摄取的局部区域。通过手术标本的组织病理学检查和CT表现，该病变被诊断为骨样骨瘤。由于放射学表现对骨样骨瘤与其他成骨性肿瘤的鉴别具有非常重要的意义，当主要症状为疼痛且传统X线检查无诊断价值时，CT是首选的检查方法。
