Internal carotid artery pseudoaneurysm due to head trauma is an extremely rare but life-threatening condition. A pseudoaneurysm in the cavernous segment of the internal carotid artery should be considered in patients with ocular region injury, unilateral vision loss and delayed epistaxis. In cases of cavernous carotid pseudoaneurysm, a period between trauma and the first episode of epistaxis is usually observed. In this paper, a 36-year-old patient with cavernous carotid pseudoaneurysm related to head trauma is presented. The patient's epistaxis started approximately 5 months after the trauma. On his examination, a pulsatile mass in the left nasal cavity was detected, and a diagnosis of giant cavernous carotid pseudoaneurysm was made with computed tomography-angiography imaging. Then, he was successfully treated with coil embolization in the interventional radiology unit.
