Computed tomography (CT) scans revealed abnormalities in 83% of patients with hemifacial spasm, frequently showing dolichoectatic vertebrobasilar arteries. CT is a valuable tool for diagnosing hemifacial spasm.

Area of Science:

  • Neurology
  • Radiology
  • Neurosurgery

Background:

  • Hemifacial spasm is a neurological disorder characterized by involuntary contractions of facial muscles.
  • The underlying causes of hemifacial spasm are not always clear, but vascular compression of cranial nerves is often implicated.

Purpose of the Study:

  • To evaluate the utility of computed tomography (CT) in diagnosing hemifacial spasm.
  • To investigate the association between hemifacial spasm and vertebrobasilar artery abnormalities.

Main Methods:

  • A cohort of 46 patients with typical hemifacial spasm underwent CT scans.
  • Imaging findings were analyzed for abnormalities, including tumors and vertebrobasilar artery characteristics.

Main Results:

Related Experiment Videos

  • CT scans showed abnormalities in 38 patients (83%).
  • Two patients had tumors, and 36 patients exhibited dolichoectatic vertebrobasilar arteries.
  • In 92% of cases with dolichoectatic arteries, the convexity pointed towards the side of the spasm.

Conclusions:

  • CT is a worthwhile diagnostic procedure for evaluating hemifacial spasm.
  • Dolichoectatic vertebrobasilar arteries are frequently associated with hemifacial spasm, suggesting a potential causative or contributing role.
