腹外硬纤维瘤是位于骨骼系统的深部纤维瘤病的一个亚型,在组织学上虽属良性病变但常呈浸润性生长,虽从不发生转移但常可复发。作者对18例,共27个腹外硬纤维瘤进行MRI检查和进行两种放射性核素:~(99m)锝二巯基丁二酸(~(99m)Tc)、~(67)镓柠檬酸(~(67)Ga)核素扫描,目的在于探索MRI和核素扫描对本病的诊断价值。18例共27个腹外硬纤维瘤均经组织学证实。女13例,男5例。年龄11～65岁。肿 Extraabdominal desmoidoma is a subtype of deep fibromatosis located in the skeletal system. Although it is histologically benign, it often shows invasive growth. Although it never metastasizes, it can often recur. The authors performed MRI examinations and performed two kinds of radionuclides in 18 cases of 27 extraabdominal dural fibroids: ~(99m)pyridylsuccinic acid (~(99m)Tc), ~(67) citric acid ( The ~(67)Ga) radionuclide scan was designed to explore the diagnostic value of MRI and radionuclide scans for this disease. A total of 27 cases of extradural desmoid tumors were confirmed by histology. There were 13 females and 5 males. Age 11 to 65 years old. swollen
