“…Among the 82 patients reported with auricular AVMs ( Table 2 ), the majority underwent endovascular embolization (37 patients) and embolization followed by excision (25 patients), while the minority were treated with excision (8 patients) and some had only observation without intervention (12 patients) [ 5 – 22 ]. Incomplete devascularization of the auricular AVMs has been reported in 16 patients (43%) following embolization [ 13 , 14 ].…”

“…There was no recurrence or re-expansion of auricular AVMs after treatment. Among the 21 patients with parotid AVMs ( Table 3 ), the majority underwent surgical excision (8 patients) and embolization (5 patients), and embolization with sclerotherapy (4 patients), while a few patients underwent embolization followed by excision (3 patients), and only 1 had sclerotherapy [ 5 , 22 – 27 ]. Although no recurrence was detected in any of the AVM cases, there was incomplete involution in 3 cases (60%) of parotid AVMs following embolization [ 23 ].…”

Patient: Female, 40-year-old Final Diagnosis: Arterio-venous malformation Symptoms: Neck swelling Medication: — Clinical Procedure: Coil embolization • surgical resection Specialty: Radiology Objective: Rare disease Background: Extracranial arteriovenous malformations (AVMs) of the parotid gland and auricle are rarely encountered. Management of these AVMs depends on the Schobinger stage and their flow characteristics. We present a rare case of an AVM involving the parotid and auricle concurrently. The clinical and imaging features of these high-flow vascular malformations and their treatment options are discussed and we provide a review of the literature. Case Report: A 40-year-old woman presented with a large 6.4×6.0×13.0 cm high-flow Schobinger stage II high-flow AVM of the parotid gland and auricle. Diagnostic imaging included magnetic resonance imaging (MRI) and conventional catheter angiogram, which defined the vascular anatomy and flow characteristics of the AVM. She was treated with preoperative endovascular embolization followed by surgical excision and free-tissue transfer reconstruction on the next day. The results were excellent, with no recurrence over 3.5 years of follow-up. Conclusions: This is the second case reported in the literature of high-flow AVM concurrently involving the parotid gland and auricle, treated with perioperative embolization followed by surgical excision and grafting. Management of AVMs requires a multidisciplinary team approach and understanding of the natural history of the lesion. Although total surgical resection is the criterion standard for these AVMs, endovascular embolization is an alternative treatment that can be used as an adjunct to surgery. Furthermore, perioperative embolization can decrease the vascularity of the lesion and effectively reduce blood loss during AVM surgery.

“…Super Selective pre-surgical embolization (a procedure performed by interventional radiologist that allows the improvement performance of subsequent surgery interventions , & that are constantly evolving into standalone therapeutic modalities) is suggested 24-72 hours before surgery to decrease the risk of extensive intraoperative bleeding & reduce tumor vasculature [1,3,4,10,28,47], especially in cases where the hemangioma is extensive or the supplying vessel is a major one, that's why Before surgery, the vascular supply of the tumor a thorough imaging study by angio MRI (MRA) aimed at detecting the vascular supply (main & collateral) should be analyzed in order to avoid intraoperative bleeding complications [3,24,48,49]. For small lesions, surgical excision poses little difficulty, in extensive lesions the facial nerve may be difficult to identify and should be monitored intraoperatively [3].…”

Parotid gland is involved in many inflammatory and neoplastic conditions. Many a times, it is difficult to ascertain the type of swelling by clinical examination. The anatomy and various abnormalities of the glands are very easily visualized by high-frequency ultrasound. Ultrasound can confirm the presence of the mass with sensitivity up to 100%. It can demonstrate whether a lesion is located in the parotid gland or outside. It can help in differentiating benign from malignant neoplasms and local staging of the mass in malignant lesions. In addition, ultrasound can identify those entities that may not need surgical intervention. The glands appear enlarged and show altered echopattern in acute inflammation and may be normal or reduce in size in chronic inflammation. Other pathologies that involve salivary glands are sialolithiasis and various benign and malignant neoplasms. Ultrasound many times suggests final diagnosis or supplies important differential diagnosis. In this article, the use of high-frequency ultrasound in parotid disease is discussed, and sonographic features of different parotid pathologies are reviewed with examples illustrated. High-frequency ultrasound is the first and many a times the only imaging investigation done for evaluation of parotid glands.
