A year-old lady presented with swelling on the right side of the ckrsoid associated with continuous headache for 1 month. Her general physical examination was normal. Local examination revealed a pulsatile swelling on the right temporal-occipital region of the scalp.

Few dilated veins were noted in this region. On auscultation, a bruit was detected over the lesion.

Other systemic examination was normal, including thyroid, breast, and musculoskeletal system. Patient underwent computed tomography of the brain along with angiography. Aneurysmal dilated mass of vessels were detected in the right temporal-occipital region of scalp in the subcutaneous plane [ Cirsoix 1 ], which enhanced markedly. Feeding vessel was from the occipital artery posteriorly and the superficial temporal aneudysm [ Figure 2 ].


Large draining veins were noted running anteriorly and posterior to the occiput [ Figure 3 ].

A diagnosis of cirsoid aneurysm of scalp was made. Patient was advised to undergo excision of the aneurysm, but the patient refused surgery. She was discharged with an advice of regular follow-up. Unenhanced axial CT image shows a serpiginous subcutaneous mass in the right temporal-occipital region. Contrast-enhanced axial CT image shows marked contrast enhancement within the cirsoid aneurysm. Cirsoid aneurysms of the scalp were first described in by Brecht.

They are usually congenital in etiology.

However, traumatic fistulas have also been described. However, this condition is not life-threatening. Endovascular and percutaneous occlusion of the fistulas have been described. However, the results have been mixed. Differential diagnosis of a pulsatile scalp swelling includes the following: This condition is almost always a result of blunt or penetrating head trauma. Clinical examination with imaging confirms the diagnosis. Simple elective ligation and excision of the aneurysm are curative.

A-V malformations may be congenital or traumatic in origin. Clinical manifestation may include a loud continuous bruit, hemorrhage and throbbing headache, and in severe cases scalp necrosis.


Angiography is the investigation of choice.
