“…These lesions are challenging to treat due to their multiplex vascular anatomy and the degree of the venous extension in the scalp [17]. Excision of the entire scalp AVM necessitates a thorough understanding of the nature of the malformation including the anatomy of the feeding vessels, draining veins, and the nidus [7]. Given the possibility of cortical venous reflux and the possible risk of venous hypertension, cerebral venous drainage should be evaluated and taken into account when deciding on treatments [11].…”

Scalp arteriovenous malformations (AVMs) are rare lesions that arise due to a pathological fistulous connection between scalp arterial feeders and draining veins without the involvement of capillary beds.Here, we report a case of a 17-year-old male who presented with an enlarging, pulsatile, mass in the scalp of the parietal region with mild headaches and was diagnosed with a scalp AVM that was treated successfully with endovascular trans-arterial embolization. Scalp AVMs are uncommon extracranial vascular abnormalities that neurosurgeons hardly ever see. To precisely define the angiographic architecture of an AVM and to organize further management, digital subtraction angiography is crucial.

“…Scalp AVMs are typically assumed to be congenital, although they have also been documented to occur following infection, and trauma [5,6]. They can occur at any age and have an incidence of 8.1% out of all AVMs [7]. Patients usually present complaining of an enlarging, pulsatile mass, headaches, and tinnitus [8,9].…”

“…Recently, endovascular therapy has become the most extensively accepted as a single treatment or combined with open surgery for some complex cases. Endovascular embolization is preferred for small lesions (<4 cm) and fewer feeding/draining vessels ( 19 , 20 ). It has also been used to reduce excessive hemorrhage during surgical procedure.…”

BackgroundScalp arteriovenous malformations (AVM) are rare vascular malformations reported only in small case series. Scalp AVMs usually present with symptoms, including headache, tinnitus, epilepsy, cerebral ischemia, and necrosis of the scalp, which can cause functional, cosmetic, and psychological problems. There are many difficulties in the treatment of scalp AVM because of its complex characteristics of vascular anatomy, non-uniform structure, and intracranial-extracranial anastomosis.Case descriptionTo illustrate the endovascular treatment of scalp AVM via direct percutaneous puncture while traditional arterial and venous approaches were not available. In this report, access was obtained through a direct puncture of the enlarged frontal vein. Onyx-18 was injected through a microcatheter to occlude draining veins, fistulous connection, and the feeders. An 18-gauge indwelling needle was inserted into draining veins directly. Postembolization angiography demonstrated complete sAVM occlusion immediately and no non-targeted embolization. At a 1-year follow-up, no procedure-related complications and evidence of recurrence were observed.ConclusionThe technique of endovascular embolization via direct percutaneous puncture approach is safe, rapid, and effective for specific sAVM. Treatment options should be made in terms of size, vascular anatomical characteristics of the lesions, patient's preference, cosmetic factors, and available expertise.

“…Scalp arteriovenous malformation (AVM) is a rare congenital entity, accounting for only 8.1% of all AVM cases. 1 Generally, scalp AVM presents as a small pulsatile mass; but with time, if untreated, it will progressively enlarge and spread to the entire scalp, giving a grotesque appearance and involves the craniofacial structures and skull bone and even extends intracranially, leading to seizures and hemorrhages. in characterizing the structural complexity, location and the extent of the lesion and assist in appropriate preoperative investigation.…”

Scalp arteriovenous malformation (AVM) accounts for only 8.1% of all AVM cases. These lesions are made up of an abnormal fistulous tangle of tortuous dysmorphic network of vessels “vascular nidus” directly connecting between the feeding arteries and draining veins, without capillary connection, located within the incision subcutaneous layer. With time, these congenital lesions may evolve and enlarge and clinically manifest with variable features. The only effective method of preventing evolution of these malformations is to exclude the lesion completely from the circulation. Involvement of the orbit and face may cause severe facial disfigurement, proptosis, visual obstruction and even facial palsy. These lesions may be complicated by ulceration, infection and profuse bleeding. We present a rare case of 40-year-old female with a recurrent congenital scalp-orbital AVM causing proptosis, visual obstruction on the right eye with severe facial disfigurement. The lesion was successfully excised with acceptable cosmesis and removal of the visual obstruction. A brief literature review, imaging findings and the surgical techniques have been presented.
