Treatment of Simple Bone Cyst by Corticosteroid Injection: A Case Report

類固醇注射治療單腔骨性囊腫:病例報告

摘要


單腔骨性囊腫約佔有原發性骨腫瘤的百分之三。這些良性之病灶好發於成長中長骨的骨骺部,尤其是肱骨及股骨。目前致病機轉尚未清楚。在幾種治療方法中,直接於囊腫內注射類固醇為一種簡單且有效的方法。在以前的研究及文獻中,曾有提出理論認為類固醇可抑制滲液及前列腺素之分泌,進而阻止囊腫變大且促進骨生長。文獻中報告注射類固醇治療單腔骨性囊腫,成功率甚至高達百分之九十六,不亞於手術治療法。但在台灣此治療方法常被忽略,本文即報告一例經類固醇注射而癒合良好之單腔骨性囊腫,期能使該療法更受重視。

並列摘要


Simple bone cyst (SBC) accounts for 3% of biopsied primary bone tumors. These benign lesions often occur in the metaphyseal region of growing bones, especially the humerus and femur. The pathogenesis is uncertain. Among the treatment options, corticosteroid injection is a simple and effective method. A case of simple bone cyst with pathological fracture over right proximal humerus was treated with intra-lesional methyiprednisolone acetate (MPA) injection. The lesion had healed well four months later. This case is presented to emphasize the importance of methylprednisolone acetate injection in the treatment of simple bone cyst.
