Figure 3

(a) Magnetic resonance imaging, axial projection. A large mass with cystic degeneration (asterisk) dislocating the root of the tongue is seen in the left parapharyngeal space. Stretched pterygoid muscles are shown with arrows. (b) Coronal projection shows the limits of the tumor (upper: the skull base; lower: the level of the submandibular salivary gland). Double arrow shows the laterally dislocated third branch of the trigeminal nerve on the left side. Note the normal proximal segment of the V3 on the right side (thin arrow).
