Solitary, asymptomatic, posterior, vertebral, intracanal, cervical spine osteochondroma

Osteochondromas are common benign tumors most often occurring in the metadiaphyseal region of long bones. Spinal osteochondromas, however, are rare. Only one to four percent of osteochondromas occur in the spine. We present a case of a possible solitary osteochondroma (arising from the posterior C4 vertebral body and protruding into the central canal) as an incidental finding in an eight year-old female who was imaged after cervical spine trauma.
