The incidence of aneurysmal bone cysts is 0.14 cases per 100,000 individuals. Parosteal aneurysmal bone cysts are the least prevalent subtype and represent 7% of all aneurysmal bone cysts. We present the case of a 38-year-old male patient with pain and bulging in his right arm for eight months. He had previously been diagnosed as presenting giant-cell tumor, but his slides were reviewed and his condition was then diagnosed as parosteal aneurysmal bone cyst. The patient was treated with corticosteroid and calcitonin infiltration into the lesion and evolved with clinical and radiological improvement within the first five weeks after the operation.
骨动脉瘤样囊肿的发病率为每10万人中有0.14例。骨旁动脉瘤样囊肿是最不常见的亚型，占所有骨动脉瘤样囊肿的7%。我们报告一例38岁男性患者，其右臂疼痛和肿胀8个月。他之前被诊断为骨巨细胞瘤，但对其切片进行复查后，他的病情被诊断为骨旁动脉瘤样囊肿。该患者接受了病变内皮质类固醇和降钙素注射治疗，术后前5周临床和影像学表现均有改善。
