De Novo dural arteriovenous fistulas after endovascular treatment: Case illustration and literature review
We present the case of a 69-year-old female with de novo formation of three dAVFs in different anatomic locations after successive endovascular treatments. The patient's initial dAVF was identified in the right posterior frontal convexity region and obliterated with transarterial and transvenous embolization. The patient returned eight years later due to left-sided pulsatile tinnitus and a new dAVF in the left greater sphenoid wing region was seen on angiography. This was treated with transvenous embolization with complete resolution. One year later, she developed left sided pulsatile tinnitus again and was found to have a...

E-213 De novo dural arteriovenous fistulas after endovascular treatment: case illustration and literature review
ConclusionGiven the evolving treatments available for dAVFs, it is important to have proper follow-up to further understand the relationship between EVT and dAVF formation. Expanding current research on dAVF treatments and outcomes will allow for better prevention of subsequent dural arteriovenous malformations.Disclosures E. Dowlati: None. E. Duquette: None. D.

Health effects related to exposure of static magnetic fields and acoustic noise —comparison between MR and CT radiographers
ConclusionNo significant differences in symptom prevalence were seen between MR and CT radiographers. However, working at 3T increased the risk of SMF symptoms, and stress increased adverse health effects. Noise nuisance was considered more problematic by CT than MR personnel.Key Points•No significant differences in symptom prevalence were seen between MR and CT radiographers.•Working at ≥ 3 T doubled the odds of experiencing SMF symptoms (vertigo/dizziness, nausea, metallic taste, and/or illusion of movement) as compared to working exclusively at ≤ 1.5 T.•Work-related acoustic noise was less well mitigated and w...

Endoscopic Transcanal and Transmastoid Laser-Assisted Resection of Middle Ear Capillary Hemangioma
Conclusions: Capillary hemangiomas are an uncommon cause of vascular middle ear lesions in adults and typically present with symptoms of aural fullness, pulsatile tinnitus, conductive hearing loss, otalgia, and vertigo. Surgery resection provides definitive treatment and the use of laser ablation techniques can allow for hemostasis and excellent visualization.

Pituicytoma: Four cases with unusual imaging features and a literature review
CONCLUSION: Our cases highlight the unusual imaging manifestations of PTs. Recognizing these imaging features plays an important role in the preoperative diagnosis, treatment, and postsurgery monitoring of PTs.PMID:34847317
