Magnetic Resonance Imaging Features of Medial Canthal Tendon in Centurion Syndrome

ABSTRACT

Purpose

To describe the magnetic resonance imaging (MRI) features of the medial canthal tendon (MCT) insertion in a series of patients of the Centurion syndrome.

Methods

This was a prospective study carried out over a period of 1 year. All patients clinically diagnosed with Centurion syndrome underwent MRI with surface coils. The insertion of both the limbs (anterior and posterior) of the MCT was studied radio-logically and correlated clinically.

Results

We recruited six patients, of whom four were males. The anterior limb of the MCT was found to insert anterior to the anterior lacrimal crest in three, normally inserted in two, and thinned out and mal-developed in one. None of the patients with normal insertion had the classical beak sign or prominent nasal bridge.

Conclusion

The anterior limb of the MCT may not always be inserted anteriorly in cases of Centurion syndrome; it can be normal or mal-developed. Disinsertion of the MCT, which is the most common procedure done for Centurion syndrome, might not be helpful in cases where the MCT is normally inserted or mal-developed.
