Osteoid Osteoma of The Lumbar Spine: A Case Report

Abstract

Osteoid osteoma is a benign bone tumor that rarely involves the spine. In this paper, an osteoid osteoma of the L5 vertebra, involving the left pedicle, has been presented. A 21-year-old male patient presented with low back pain, which worsens at night. Neurological examination was normal. Computed tomography of the lumbar spine has revealed a lesion with an oval nidus surrounded by sclerosis, involving the left pedicle of the L5 vertebra, which was considered as an osteoid osteoma. The patient was operated on and the tumor was completely removed. Histopathological examination was confirmative. The patient was discharged 2 days after the surgery as pain-free. Osteoid osteoma, although rarely involving the spine, should be included in the differential diagnosis of patients presenting with low back pain, especially if the patient is young and the pain worsens at night. ©2008, Firat University, Medical Faculty.

Lomber Omurganın Osteoid Osteomu: Olgu Sunumu

Öz

Osteoid osteom, omurgada son derece nadir görülen iyi huylu bir kemik tümörüdür. Bu çalışmada L5 vertebrasının sol pedikülünü tutan bir osteoid osteom olgusu sunulmaktadır. Yirmi bir yaşında erkek hasta kliniğimize, özellikle geceleri artan, bel ağrısı şikayetiyle başvurdu. Yapılan nörolojik muayenesinde herhangi bir patoloji saptanmadı. Bilgisayarlı tomografi tetkikinde, sol L5 pedikülünde, oval bir nidusu çevreleyen skleroz görüntüsüyle, tipik bir osteoid osteom saptandı. Hasta bu nedenle operasyona alınarak, kemik tümör çıkartıldı. Histopatolojik inceleme tanıyı teyit etti. Hasta operasyondan iki gün sonra ağrısız olarak taburcu edildi. Osteoid osteom, her ne kadar omurgada nadiren görülse de, özellikle genç ve şikayetleri geceleri daha çok artan bel ağrılı hastaların ayırıcı tanısında mutlaka yer almalıdır. ©2008, Fırat Üniversitesi, Tıp Fakültesi
