“…Although no universally accepted classification of STA aneurysms based on their etiology has been established, they have been classified as traumatic, iatrogenic, and spontaneous. [ 2 3 5 7 8 10 12 13 14 15 16 18 19 21 22 ] In our discussion, we use the designation traumatic and spontaneous (nontraumatic) aneurysms to describe traumatic- and iatrogenic aneurysms. Schechter and Gutstein[ 18 ] reported that 92% of STA aneurysms were traumatic, and the other 8% were spontaneous.…”

“…[ 5 ] Spontaneous aneurysms, on the other hand, are true aneurysms that tend to be associated with arteriosclerosis. [ 14 21 ] Very rarely, spontaneous STA aneurysms are histologically dissecting aneurysms or pseudoaneurysms. Fujii et al .…”

“…The histologic diagnosis was dissecting aneurysm in one patient[ 5 ] and pseudoaneurysm in the other three. [ 14 ] We report a fourth patient with a spontaneous STA pseudoaneurysm and discuss its potential pathogenesis, the background of patients with these aneurysms, and the anatomical features of these lesions.…”

A spontaneous superficial temporal artery pseudoaneurysm possibly related to atherosclerosis: Case report and review of literature

Background:Spontaneous superficial temporal artery (STA) pseudoaneurysms are very rare; only four cases, including ours, have been reported to date. Therefore, the cause of them has not been studied.Case Description:A 57-year-old woman was admitted to our hospital with a pulsatile mass in the left preauricular region. Her medical history included hypertension, dyslipidemia, and angina pectoris. She denied a history of head injury or minor head trauma. Three-dimensional computed tomography angiography showed a well-enhanced saccular aneurysm on the main trunk of the STA. To prevent rupture it was removed surgically. The histological diagnosis was pseudoaneurysm with atherosclerosis. By the 2nd postoperative day, she had completely recovered and was discharged home. There has been no relapse.Conclusions:As all four documented patients were at high risk for atherosclerosis, we posit that a causal factor was weakening of the arterial wall due to atherosclerosis and chronic pressure on the STA from anatomical structures. Here, we present histological evidence to support this hypothesis.

“…Although this phenomenon has been described in 1 previous case series, these were 3 elderly female patients with more proximal lesions of the superficial temporal artery. 8,9 Nii et al 8 surmised a possible association with minor repetitive trauma of wearing eyeglasses. Patient 1 and the female patients studied by Nii et al 8 shared a similar lesion location at the proximal superficial temporal artery that is not classic for the most vulnerable portion of the superficial temporal artery prone to PA arising from blunt trauma.…”

“…1,7 Spontaneous formation of PAs of the superficial temporal artery has been reported, but it is thought to be extremely rare. 8 A PA presents clinically as a compressible, pulsatile mass, which can be painful, growing in size, and at times associated with headaches. The differential diagnosis includes lipoma, hematoma, cyst, abscess, lymph node, hemangioma/vascular malformation, or other soft tissue mass.…”

A pseudoaneurysm (PA) is a vascular lesion occurring along an artery most often associated with previous trauma. It presents clinically as a compressible, pulsatile mass, which can be painful, growing, and associated with headaches. We report a series of 4 pediatric patients referred for management of a "cyst" who had superficial craniofacial PAs arising in a variety of different locations with a variable history of antecedent trauma.This is an institutional review board-approved study of 4 consecutive patients presenting to the pediatric plastic surgery division with a diagnosis of PA between July 2012 and November 2013.The patients were initially referred for management of cyst. Each presented with compressible, pulsatile masses arising in varying locations along the superficial temporal or occipital arteries of the face and scalp. Three of the patients did not have a history of recent previous trauma. In the patients without history of trauma, further workup with duplex ultrasound was performed. In cases where the entire course of the artery could not be visualized by ultrasound, magnetic resonance angiography was performed to rule out an intracranial source of the lesion. Three lesions were excised with pathologic confirmation of the diagnosis of PA. All masses and associated symptoms resolved after the excision.Craniofacial PAs can occur in the pediatric population with a variable history of antecedent trauma. Awareness of this clinical phenomenon can help guide proper diagnosis for planning of safe, effective treatment. Surgical excision provides a safe, aesthetic result.
