Undifferentiated carcinoma with perineural spread in a 43-year-old male patient. Undifferentiated carcinoma with perineural spread in a 43-year-old male patient. A, T1-weighted image shows perineural spread along the auriculotemporal (thin white arrow) branch of trigeminal nerve VIII, the facial nerve (black arrow), and the superficial branch of the facial nerve (thick white arrow). B, T1-weighted image of the same patient, a caudal view of image A. Note the longitudinal spread along the auriculotemporal (thin white arrow) and facial nerves: backward spread (black arrow) toward the stylomastoid foramen and forward spread along the superficial branch (thick white arrow).
