Case Report

Introduction

Conventional osteochondroma is the most common type of benign bone tumor [1, 2]. It usually originates near the end of a long bone and sometimes grows away from the joint. An osteochondroma is characterized by an osseous component capped by cartilage and is connected to bone by a stalk [3]. Spinal osteochondroma comprises only 3% of solitary osteochondroma but may cause spinal cord compression [4, 5, 6]. A paraarticular or juxtaarticular osteochondroma is a rare osteocartilagenous tumor that arises in the soft tissue adjacent to a joint without attachment to bone [2, 3, 7]. Although several case reports have described paraarticular osteochondromas, all of the lesions reported were adjacent to the joints of the extremities, most of which involved the knee region [3, 8]. To our knowledge, no case of spinal paraarticular osteochondromas has been reported. In this report, we present a patient with a paraarticular osteochondroma arising in the spinal canal just medial to the...
