Abstract

<p>We describe a case of a patient with neurofibromatosis type 1 who developed thrombosed cervical internal carotid artery (ICA) aneurysm combined with subcutaneous hematoma originating from the facial artery. A 25-year-old woman developed airway obstruction due to progressive neck swelling. Computed tomography (CT) showed massive subcutaneous hematoma in the neck and subsequent angiography with arterial catheterization showed extravasation from the left facial artery and a fusiform aneurysm located at the ICA. The left facial artery was embolized with coils. Eleven hours later, the neck swelling in the patient enlarged. CT angiography demonstrated enlargement of the fusiform aneurysm. The aneurysm was trapped by coil embolization of the left ICA. The patient did not develop any ischemic complications in the brain, but suffered in the subcutaneous abscess in the neck. After removal of the lesion, her postoperative course was uneventful.</p>
