[Stylocarotid syndrome: a case report]

The American otolaryngologist Eagle was the first to describe styloid syndrome in 1937 and the syndrome was named after him (Eagle's syndrome). The original description of two separate syndromes is connected with his name: classical syndrome, which almost constantly occurs after tonsillectomy and carotid artery syndrome, which occurs without tonsillectomy and also in cases when stylohyoid complex compresses the carotid segments and perivascular sympathetic fibers. In the following years, two more syndromes were defined: stylohyoid and pseudostylohyoid, which according to their manifestations, correspond to the genuine classical form.

A 40-year-old male is presented, with a history of 3-year duration of pains in the upper part of the left side of the neck, in the left eye and its surroundings. Pain occurrences were not regular. Throbbing pains were most often provoked by sudden head movements and neck compression. He was healthy until the onset of these problems. The findings of all examinations were normal. The applied prophylactic therapy, typical for cluster headache, was without any effect. On 64-MSCT (multislice computed tomography), the neck arteries did not show any intraluminal pathology. The styloid processes were of normal length. On the left side, the styloid process tip pressed the internal carotid artery disturbing its longitudinal axis.

In our presentation, the defined lengths of the styloid processes were normal. The medial angulation of the left styloid process was more expressed reaching 63.5 degrees (the right side angulation was normal). Persistent and throbbing pain in the region of the left eye with backward projection suggested compression on the internal carotid artery. Pains were most frequently provoked by head turning and neck compression. 64-MSCT diagnostics enabled us to determine the characteristics of styloid processes and their relation to the internal carotid artery. Improvement was achieved by administration of antiepileptic (gabapentin) and antidepressant (amitriptyline) drugs.
