Superficial temporal artery pseudoaneurysm: 2 cases

Pseudoaneurysm of the superficial temporal artery causes tumefaction in the temporal region. Herein, we report two cases. Case 1 : a 32-year-old man presented with a slightly pulsatile nodular formation measuring 2 cm in the right temporal region that had appeared nine months after traumatic injury. A diagnosis of superficial temporal artery pseudoaneurysm was considered. Excision was performed with ligation of the afferent and efferent artery. The clinical diagnosis was confirmed by histopathology. Case 2 : a 24-year-old man presented with a nonpulsatile subcutaneous tumefaction on his left temple. Surgery was proposed based on a supposed epidermal cyst. However, the perioperative aspect suggested a lesion of arterial origin and excision was performed following ligation of the afferent and efferent artery. Pseudoaneurysm of the superficial temporal artery must be considered for all temporal cutaneous formations, particularly when there is a history of trauma. The clinical diagnosis may be confirmed by Doppler ultrasound. Surgery is the treatment of reference.
