case_images: Axial contrast-enhanced cervical computed tomography scan after 3 cycles of cetuximab plus platinum-based chemotherapy. The scan shows a marked reduction in the tumor. A large hypodense area with air bubbles and peripheral enhancing corresponding to necrosis is seen in the masticator space. A partial tumor remission was considered.
