Abstract

Solitary osteochondromas, which are the most common benign bone tumors of long bones, are rarely found in the vertebral column. A 16-year-old female patient presented with a hard palpable mass at lower lumbar region like a congenital deformity. Plain radiography illustrated a well-defined solid mass arising from the posterior elements of the L3 and ruled out any congenital anomalies. A computed tomography scan further determined a mass that arose from the spinous process of L3. The tumor was excised en bloc through a posterior approach and histopathological examination verified the diagnosis of osteocondroma.Osteochondromas are rarely found in the spine, when present in the spine, however, have a predilection for cervical or upper thoracic region arising usually from lamina of vertebrae and are rare in lumbosacral region and very rare at spinous process of the vertebrae.We present a case of osteochondroma locates in lumbar region and spinous process of vertebrae with unusual presentation and was considered clinically as congenital lumbar kyphosis.

Summary

Introduction

Osteochondroma is the most common primary benign bone tumor. this tumor rarely involves the spine and even more rarely involves the lower lumbar region [1]. Osteochondromas are rarely found in the spine, when present in the spine, have a predilection for cervical or upper thoracic region arising usually from lamina of vertebrae and are rare in lumbosacral region and very rare at spinous process of the vertebrae. We present a case of osteochondroma locates in lumbar region and spinous process of vertebrae with unusual presentation and was considered clinically as congenital lumbar kyphosis.
