“…Complications of STA AVM include pain, ischemic necrosis or ulceration, and hemorrhage [ 2 ]. Differential diagnoses include epidermoid cyst, abscess, hematoma, inflammatory lesion, neoplasm, pseudo-aneurysm, true aneurysm, arterial occlusion, and dissection [ 8 , 11 , 16 ]. Our patient presented with discomfort over the left temporal area in addition to pulsatile tinnitus and a pulsatile mass that was tender to palpation on physical exam.…”

“…Disadvantages of arterial angiography include complications with access. CTA and MRA have the advantages of being non-invasive and more accessible [ 16 ]. Kang et al noted that CT temporal bone has a higher sensitivity to middle-ear abnormalities, while MRA can help demonstrate neoplasm and vascular abnormalities in addition to soft tumor involvement related to temporomandibular joint dysfunction and parotid gland [ 17 , 18 ].…”

Patient: Female, 76-year-old Final Diagnosis: Spontaneous superficial temporal artery arteriovenous malformation Symptoms: Pulsatile mass • tenderness • enlarging • tinnitus Clinical Procedure: Open ligation and excision Specialty: Surgery Objective: Rare disease Background: An arteriovenous malformation (AVM) is an abnormal connection between an artery and a vein, bypassing the capillary network. An AVM of the superficial temporal artery (STA) can occur after trauma, iatrogenic injury, infection, or spontaneously. Spontaneous, or iatrogenic, presentations of STA AVM are thought to be rare, with very few reported cases. Symptoms include local pain, headache, tinnitus, or paresthesia, in addition to a palpable mass associated with thrill on palpation. Options for diagnosis include intra-arterial angiography, doppler ultrasound, magnetic resonance angiography (MRA), and computed tomography angiography (CTA). Current management options include surgical excision, ligation, and embolization; however, it is unknown which treatment is superior in terms of recurrence and which carries a lower risk of complications. Case Report: We present a case of a spontaneous STA AVM in a 76-year-old woman with past medical history significant for seasonal allergies and hyperlipidemia, who presented with pulsatile tinnitus and a palpable, tender mass located to the left temporal area. The mass had been present for several years, with gradual increase in size two to three years prior to presentation. She denied any history of trauma or procedure prior to presentation of the pulsatile mass. She underwent open excision with complete resolution of symptoms and no recurrence at 11-month follow-up. Conclusions: AVM of the STA is a condition that can occur secondary to trauma, infection, iatrogenic injury, or spontaneously. Spontaneous, or iatrogenic, presentations of STA AVM are thought to be rare, with very few cases documented in the literature. Surgical treatment remains the standard of management, with options including surgical excision, ligation, or embolization.
