Pseudoaneurysm, or false aneurysm, presents rarely as a cause of facial tumor. The condition should be considered by primary care physicians as a cause of facial masses in patients with recent traumatic head injuries. Approximately 337 pseudo aneurysms of the superficial temporal artery (STA) have been reported in the literature since 1644.A good history and careful palpation, auscultation, and ancillary testing easily differentiate pseudo aneurysms from cysts, dermal lesions, and AV fistulas. Timely referral & surgical resection of a pseudoaneurysm is the key in management to avoid complications such as hemorrhage, enlargement and compression of nerves and vessels. We present two cases of traumatic pseudoaneurysm arising from the STA seen in our institution during last 2years period, which suggests that this condition may be more common than reported. We have reviewed the anatomy of the STA and the mechanisms of injury; pathophysiology, pertinent history, and physical findings; differential diagnosis and other diagnostic considerations; INTRODUCTION: Pseudo aneurysms of the superficial temporal artery are a rare and potentially curable cause of facial lumps. Approximately 337 pseudo aneurysms of the superficial temporal artery (STA) have been reported in the literature since 1644. Most pseudo aneurysms are formed as a result of blunt trauma and present as painless, pulsatile tumors that may be associated with neuropathic findings and enlarge in size. Without careful evaluation in the primary care setting, pseudo aneurysms can be easily misdiagnosed and improperly managed. They can, however, be accurately diagnosed through physical examination alone and subsequently treated with surgical ligation. Here we are presenting two cases of traumatic pseudo aneurysms of the superficial temporal artery caused by blunt injury and discuss pertinent diagnosis and treatment options, as well as provide a brief review of the microanatomy and histopathology of pseudo aneurysms. CASE REPORT - I: A 23-year-old farmer, who was referred by a family physician presented with an irregular pulsatile lump in the right temporal region. He had past history of injury by wooden stick at his workplace 2 months ago. He did not have loss of consciousness or laceration at the time of injury. He denied a history of congenital bleeding disorder. The initial swelling he had, after the injury subsided within 4-5 days, but a new, irregular pulsatile mass became palpable 4 to 6 weeks later. Physical examination revealed a 1.5 cm pulsatile irregular shaped lump on the right temporal region. The mass was compressible with digital pressure, but no bruit was appreciable on auscultation. Proximal compression of the temporal artery eliminated the pulsation of the mass.
