Unique case of solitary osteochondroma of left lamina of C2 presenting with neurologic deficits

Osteochondroma is the most common benign tumor of bone, and the majority arise in the appendicular skeleton. Spinal osteochondromas are uncommon, with 50% occurring in the cervical spine. Only 0.5% to 1% of spinal osteochondromas present with neurological dysfunction. Only 12 of such solitary symptomatic osteochondromas have been previously reported in the literature to arise from C2. We report an unusual case of solitary osteochondroma arising from the left lamina of C2 and presenting with neurological deficits. We also review the imaging characteristics, potential complications, and management of such lesions.
