作者收集1990～1994年的12例脊椎成骨细胞瘤,其中4例在X线于片、核素成像和CT上出现少见的影像学征象,并经手术病理证实。 例1,女,7岁。颈部疼痛、僵直18个月。颈椎正位片显示C_5右侧椎体及椎弓硬化;侧位上C_5椎体弥漫硬化,C_4亦轻度硬化。CT表现C_5椎体广泛硬化,相应的椎前、椎旁软组织肿胀。核素扫描可见C_5右半部孤立性摄取增加。 例2,女,11岁。间歇性下胸背部痛3年。查体:脊
The authors collected 12 cases of vertebral osteoblastoma from 1990 to 1994, of which 4 cases had rare radiological signs on X-ray film, radionuclide imaging, and CT, and were confirmed by operation and pathology. Example 1, female, 7 years old. Neck pain, stiffness for 18 months. Cervical anteroposterior radiographs showed C_5 right vertebral body and pedicle sclerosis; lateral position C_5 vertebral body was diffusely hardened, and C_4 was also slightly sclerotic. CT manifestations of C_5 vertebral extensive hardening, the corresponding prevertebral, paravertebral soft tissue swelling. The radionuclide scan shows an increase in solitary uptake in the right half of C_5. Example 2, female, 11 years old. Intermittent chest and back pain for 3 years. Physical examination: ridge
