Spontaneous giant pseudoaneurysm of right occipital artery: a case report

Enlarging Post-Traumatic Forehead Mass in Liver Failure: A Case Report and Proposed Algorithm for the Treatment of Pseudoaneurysms of the Superficial Temporal Artery

“…Thus, despite being invasive and carrying some risk of iatrogenic stroke, dissection, and bleeding, angiography remains the gold standard imaging modality for pseudoaneurysms. 26…”

“…The differential diagnosis for STA pseudoaneurysm often includes sebaceous cysts, epidermoid cysts, hematomas, pilar cysts, lipomas, abscesses, and swollen lymph nodes. 2,5,8,9,[26][27][28] Clinical exam reveals a slow growing, palpable mass in the temporal region that is typically painless, pulsatile, and may present with a thrill or bruit. 6 Compression of the proximal STA, near the auditory canal, will temporarily reduce the volume and pulsation of the mass.…”

“…Thus, despite being invasive and carrying some risk of iatrogenic stroke, dissection, and bleeding, angiography remains the gold standard imaging modality for pseudoaneurysms. 26 Notably, pseudoaneurysms themselves are a benign entity, but they are typically treated to decrease the risk of rupture and bleeding. In the case of active bleeding, emergent ligation and excision in the operating room should be performed to obviate the risk of hemodynamic instability.…”

“…21-23 The most common cause of injury to the STA is blunt head trauma 1 though several other etiologies have been reported including trumpeting, paintball, 24 mandibular condylar fracture, 25 and fencing. Traumatic pseudoaneurysms of other arteries of the face and scalp have also been reported, including the occipital artery 26-28 and internal maxillary artery. 29…”
