a Metastases to level II lymph nodes occur in almost all patients with cervical disease. Levels I and III occur in >50% of patients, while RPNs are present in 43% of patients. On imaging, metastatic cervical lymph nodes are predominantly solid, with moderate-to-maximal contrast enhancement and medium-to-high FDG avidity.
