Abstract :

Aneurysmal bone cyst (ABC) is an uncommon osteolytic lesion occurrs in 1.4 per 100000 patients. ABCs are benign tumors with low risk of malignant transformation (osteosarcoma). We report a case of a large ABC of the 4th lumbar vertebra resembling a kidney mass that presented with flank pain, urinary incontinence and neurological symptoms. Recurrence rate in ABC is 25%, if not completely removed. Aggressive curettage with bone grafting or en bloc resection is usually recommended. Angiography was initially performed and due to the absence of mass hypervascularity, embolization was not considered and patient underwent a complete resection in two stages. ABC can mimic renal cell carcinoma and other malignant bone tumors. In huge tumors with difficult location as in our case, we recommend two stage procedure to ensure complete resection and hence lower recurrence rate and better outcome.
