髌骨软骨母细胞瘤诊断及治疗进展

Diagnosis and treatment of patellar chondroblastoma

髌骨软骨母细胞瘤(chondroblastoma of patella)是一种发生在髌骨的少见的良性骨肿瘤,相对于骨巨细胞瘤,其在髌骨的发病率更低。同时,该肿瘤临床表现多样,可表现出各种复杂的影像学特征。因此,即使专业的骨科医生对其认识仍有可能不足。髌骨软骨母细胞瘤在X线片、CT及MRI上与骨巨细胞瘤等肿瘤的鉴别是近年来的研究焦点之一。有时它与动脉瘤样骨囊肿可合并存在,这就对进行准确的病理及影像学诊断提出了更进一步的挑战。在治疗上,病灶刮除植骨术是目前主流的手术方法,但对于是否需要在术前进行活检仍存在争议。此外,新的射频消融等技术用于治疗的前景到底如何仍未可知。

Chondroblastoma of the patella,rare occurred in patellar,is a kind of an uncommon benign bone tumor. Com pared with giant cell tumor, the morbidity of chondroblastoma is lower. Meanwhile, its clinical manifestations are various, and images are very comphcated. Therefore,the understanding of this kind of tumors may be limited even to the orthopedist. The differences of patellar chondroblastoma between other tumor in X-ray, CT and MRI is a spot in recent years. Sometimes patellar chondroblastoma coexists with aneurysmal bone cyst,which is a challenge to obtain an accurate pathological and radiological diagnosis. For the treatment, curettage and bone grafting is one the most popular method, but whether to perform a biopsy before surgery still remain controversy. Some new technique still has an unknown prospect for the treatment such as radiofrequency ablation.
