Perineural spread of mucoepidermoid carcinoma of parotid gland involving V, VI, and VII cranial nerves demonstrated on positron emission tomography/computed tomography

摘要

Perineural spread (PNS) in head and neck malignancies has been associated with extremely poor prognosis. Through this interesting case, we demonstrate the PNS of a mucoepidermoid carcinoma of parotid gland with simultaneous involvement of V, VI, and VII cranial nerves identified on positron emission tomography/computed tomography.
