摘　　要：BACKGROUND Bone lesions can present the multi-displinary team with a challenge by way of diagnosis as some lesions share many radiological and histological characteristics.Giant cell tumours of the bone(GCTB)are relatively common,benign bone tumours.Aneurysmal bone cysts(ABC)are less common benign osteolytic lesions that are histologically similar to GCTBs but produce blood filled cavities.Both GCTBs and ABCs are locally aggressive and are typically found on meta-epiphyseal regions of long bones with pelvic tumours being less common.CASE SUMMARY A 17-year old female presented with atraumatic right groin pain and was initially diagnosed with a GCTB on the right superior pubic ramus of the pelvis.The patient was treated successfully with a wide excision,curettage and bone graft and underwent open reduction and internal fixation of the right hemi-pelvis.Following further intra-operative histological investigations,the lesion was diagnosed as an ABC.CONCLUSION This patient has had an uncomplicated post-operative course,has returned to comfortable weight bearing and will be reviewed for minimum 5 yr in the outpatient setting to monitor for reoccurrence.BACKGROUND Bone lesions can present the multi-displinary team with a challenge by way of diagnosis as some lesions share many radiological and histological characteristics.Giant cell tumours of the bone(GCTB) are relatively common,benign bone tumours.Aneurysmal bone cysts(ABC) are less common benign osteolytic lesions that are histologically similar to GCTBs but produce blood filled cavities.Both GCTBs and ABCs are locally aggressive and are typically found on meta-epiphyseal regions of long bones with pelvic tumours being less common.CASE SUMMARY A 17-year old female presented with atraumatic right groin pain and was initially diagnosed with a GCTB on the right superior pubic ramus of the pelvis.The patient was treated successfully with a wide excision,curettage and bone graft and underwent open reduction and internal fixation of the right hemi-pelvis.Following further intra-operative histological investigations,the lesion was diagnosed as an ABC.CONCLUSION This patient has had an uncomplicated post-operative course,has returned to comfortable weight bearing and will be reviewed for minimum 5 yr in the outpatient setting to monitor for reoccurrence.
