16. Pleomorphic adenoma (mixed tumor) of the parotid
Note the swelling at the angle of the jaw. This is the MC benign tumor of the major and minor salivary glands. (Gi214)
Pleomorphic adenoma
T2-weighted axial MRI: There is a sharply demarcated, hyperintense, partially lobulated mass arising from the left retromandibular fossa, filling the entire left parapharyngeal space. The lesion is surrounded by a hypointense capsule. This finding is a pleomorphic adenoma. Differential diagnoses include other tumors of the parotid gland.
Pleomorphic adenoma
Oral cavity of a patient, ventral view: A protrusion of the left lateral wall of the pharynx can be seen. Further diagnostics performed on the patient confirmed a pleomorphic adenoma of the parotid gland, which expanded into the parapharyngeal space.
