In true\u2010positive cases (<jats:italic>n<\/jats:italic>\u2009=\u200933), zonal extent was correctly identified in 100%. Seventy\u2010nine% had simultaneous trigeminal nerve (V) PNS, mostly involving the auriculotemporal branch of the mandibular nerve (64%). When the causative lesion was absent (<jats:italic>n<\/jats:italic>\u2009=\u200923), the extra\u2010temporal VII demonstrated asymmetrical enhancement alone (<jats:italic>n<\/jats:italic>\u2009=\u20096), bulky expansion (<jats:italic>n<\/jats:italic>\u2009=\u20098), or extra\u2010neural spread (<jats:italic>n<\/jats:italic>\u2009=\u20099).

Coexistent V PNS was common, highlighting the need to examine V branches to allow complete treatment planning. The unique radiological patterns identified showcases disease progression. As early detection improves patient outcomes, the radiologist must look for peripheral VII involvement in\u00a0specific anatomical areas, which is within the capabilities of 3T MR neurography.<\/jats:p><\/jats:sec>","DOI":"10.1111\/1754-9485.13589","type":"journal-article","created":{"date-parts":[[2023,9,24]],"date-time":"2023-09-24T12:19:45Z","timestamp":1695557985000},"page":"41-49","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Evaluation
