The patient initially received multiple misdiagnoses and sought medical attention at various hospitals before being correctly diagnosed. Imaging studies revealed the DAVF\u2019s presence in the SW region, which led to the patient\u2019s referral to interventional radiology\/neurology, although she chose conservative observation without surgical intervention. Remarkably, the patient\u2019s PT spontaneously ceased after 30\u2009months without any apparent cause, and follow-up imaging confirmed the absence of DAVF-related abnormalities. The case highlights the importance of considering DAVF as a potential cause of PT, even when there are no evident abnormalities in proximity to the auditory apparatus. It also emphasizes the need for otolaryngologists to extend their examination to include regions beyond the temporal bone, such as the sphenoid bone and orbital areas, when PT is the exclusive symptom. The case underscores the significance of early detection and intervention for DAVFs, as they can lead to debilitating complications, despite the rare occurrence of spontaneous symptom resolution in this case.<\/jats:p>","DOI":"10.3389\/fneur.2023.1293899","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T05:06:00Z","timestamp":1704949560000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Case
