(A) PET scan before treatment showed enlarged metabolically active right cervical lymphadenopathy involving levels 2 and 3 measuring 2.1×4.3 cm. Prominent left level 2 node is also noted measuring 1.1×0.9 cm demonstrating mild increased metabolic activity. PET, positron emission tomography. (B) Post-treatment PET scan showed a mildly active right level 2 node which measures 1.4×0.6 cm with unknown significance. No other metabolically active cervical nodes identified. PET, positron emission tomography.
