Abstract
INTRODUCTION: Osteochondromas are common benign tumors of bone and spinal involvement is uncommon. Solitary spinal osteochondromas may produce a wide variety of symptoms depending on their location and relationship to adjacent neural structures. CASE PRESENTATION: Herein, we present a case of solitary osteochondroma arising from the posterior arch of C1, causing left-sided ascending numbness and paresthesia and difficulty walking. The lesion was totally resected through a posterior approach. Histopathological examination confirmed the diagnosis of benign osteochondroma. DISCUSSION: Spinal cord compression is uncommon in spinal osteochondromas because in most cases the tumor grows out of the spinal column. To prevent neurological compromise, complete surgical removal is mandatory when an intraspinal osteochondroma with cord compression is diagnosed, which also helps to prevent recurrence. Our literature review of similar cases indicates that despite the old belief that C2 is the most commonly involved vertebra for osteochondromas, C1 is actually the most commonly involved vertebra in the cervical region.
