Aneurismal bone cysts (ABCs) make up 1.4% of all bone tumors and 15% of all primary spinal tumors. Some benign primary bone lesions, such as ABCs, are aggressive (such as osteoblastoma and giant cell tumor). The clinical symptoms can be confused with other pathologies if attention is not paid. In a 23-year-old male patient who received surgery due to suspicions of hernia as a result of pain in the inguinal region, a rare aggressive ABC with involvement of the lumbar 1 vertebral posterior neural arch was detected, with neurological symptoms.

The mass, which was causing compression of the posterior neural arch and medulla, was totally removed, and pedicular screw fixation was applied to one upper and one lower level. Postoperatively, an early full recovery was obtained, and no recurrence occurred at the end of a five-year follow-up. The results were clinically and radiologically improved.
