Local tumor response seen in head and neck magnetic resonance images. Magnetic resonance images from baseline before second-line chemotherapy (a–d) showing locally advanced left maxillary sinus mass (arrows), infiltrating adjacent sinuses and skull base foramina. Follow-up magnetic resonance images (e–h) showing significant tumor shrinkage (arrows) with areas of necrosis, representing local morphological partial response
