Abstract
This case underscores the challenge of distinguishing aneurysmal bone cysts (ABC). from telangiectatic osteosarcomas when MRI shows lytic lesions with fluid-fluid levels. In a 70-year-old woman, biopsy confirmed an ABC after pathologic fracture. Curettage, grafting, and fixation led to full recovery. Accurate histologic diagnosis is essential to prevent overtreatment. Multidisciplinary assessment improves outcomes in such rare diagnostic dilemmas today.
