Abstract：
Chondromyxoid fibroma is a rare, benign tumor of the bone with excellent prognosis but a high rate of recurrence. We report a patient presenting with pain and a history of chondromyxoid fibroma of the distal left femur previously treated with multiple prior curettage and bone graft procedures. Magnetic resonance imaging and histopathology indicated a recurrence of tumor. Due to the small size of the tumor recurrence and challenges associated with prior open surgery, the patient underwent cryoablation of the lesion with computed tomography guidance. Follow-up 18 months later indicated a resolution of pain and improvement on magnetic resonance imaging, and no concerns after 20 months. To our knowledge, this is the first reported case of chondromyxoid fibroma treated with cryoablation. This case suggests cryoablation could be considered in the setting of recurrent chondromyxoid fibroma for local tumor control.
摘要：
软骨粘液样纤维瘤是一种罕见的，骨良性肿瘤预后良好，但复发率高。我们报告了一名患有疼痛和左股骨远端软骨粘液样纤维瘤病史的患者，该患者先前接受过多次刮治和植骨手术治疗。磁共振成像及组织病理学提示肿瘤复发。由于肿瘤复发的小尺寸和与先前开放手术相关的挑战，患者在计算机断层扫描指导下接受了病灶冷冻消融术.18个月后随访显示疼痛消退，磁共振成像改善，20个月后就不用担心了.据我们所知,这是首例报道的冷冻消融术治疗软骨粘液样纤维瘤病例。这种情况表明，在复发性软骨粘液样纤维瘤的情况下，可以考虑冷冻消融以控制局部肿瘤。
