The mass extends into the left posterior nare as well as the left pterygomaxillary fissure. Altered signal in the left masticator space with signal change in the medial pterygoid muscle and abnormal enhancement in the masticator space. Fluid in the left mastoid air cells. 1.9 cm right retropharyngeal node. Bilateral cervical adenopathy.  Matted nodes along the left cervical chain (levels II, III and 1b) with bulk dimensions of 9.8 x 6.7 cm. The largest on the right is 2.3 cm at level II. Bilateral supraclavicular nodes, the largest on the left 3.1 cm and on the right a solitary 1.3 cm node. Several left intraparotid lymph nodes, the largest 4.2 cm.

Bony erosion of the medial wall of the left maxillary antrum.  Soft tissue widening the left pterygomaxillary fissure. The fat plane between the mass and medial pterygoid muscle is obliterated suggesting masticator space extension. 1 cm satellite nodule (10 mm) along the medial wall of the left nasal cavity. No bony erosion of the base of the skull. Multiple enlarged lymph nodes at left level Ib, II, III, IV and V. Multiple left intraparotid nodes most of which have internal necrosis.
