Diagnosis

Congenital C6 spondylolysis

Findings

CR – Lucent defect in posterior elements of C6.

CT – Bilateral hypoplastic pedicles; lucent defects with sclerotic margins separate the vertebral body from posterior elements.

Discussion

Cervical spondylolysis can be acute or chronic. Acute is post-traumatic. Chronic is related to embryologic defect and is most common at C6. The incidence is unknown; most cases are detected incidentally. Flexion and extension radiography is necessary to determine stability. Unstable spondylolysis is treated by surgical fusion whereas stable spondylolysis is managed conservatively.
