Síndrome de Eagle. Una rara etiología de la disección de la arteria carótida interna desenmascarada por angio-TC dinámica

Abstract

Arterial dissection accounts for 2% of all ischemic strokes and up to 25% of strokes in young adults. We present this clinical case, where we objectify this rare cause of dissection using dynamic computed tomography techniques. Due to its sympto-matology a MRI-angiography was performed, where a semilunar image was observed in the wall of the right internal carotid artery, prior to its entry into the carotid foramen, compatible with carotid dissection. We complemented the evaluation with CT-angiography where it was also found that the length of both styloid processes were increased (right 47 mm and left 44 mm). Using a dynamic CT-angiography technique, in which the patient was placed in the supine position, obtaining images at rest and then in rotation and right lateral inclination, compression of the ipsilateral internal carotid artery was observed between the styloid process and the corresponding perivertebral space
