On physical examination, there was tenderness over lateral aspect of the elbow with restricted movement of elbow and wasting of forearm muscle. Swelling over elbow with no sign of inflammation or infection skin was normal. On investigation X-ray - pathological fracture of Radial head with eccentric ballooned expanded Radiolucency margin well circumscribed lesion Bone cyst (Fig. 1). MRI -mildly expansile lesion at proximally epiphysis-metaphysis adjacent to diaphyseal location of radius extending upto sub articular location abutting articular cartilage. Surgery was planned; the aim was to excise diseased part and get good functional recovery wide excision of tumor through anterolateral approach with injection of phenol (Fig. 2). Tumor bone soft tissues send for biopsy including Radial head which was involved up to articular cartilages, (Fig. 3)Radial head reconstruction was not done because ABC extended from metaphysic - diaphysis junction to epiphysis cartilage of radial head.
