Pathologic causes of the superior oblique click syndrome.

PURPOSE: To describe the clinical features in two patients with superior oblique click syndrome and the pathologic causes of their symptoms.

DESIGN

Two observational case reports.

PARTICIPANTS

Two patients.

METHODS

The clinical histories, results of physical examinations, treatment, and pathologic findings in two patients with superior oblique click syndrome are reviewed and analyzed with reference to the literature.

MAIN OUTCOME MEASURES: Relief of symptoms.

RESULTS

Both patients were operated on; one was found to have a schwannoma and the other a giant cell tumor of tendon sheath as causes of their symptoms. Symptoms were relieved by removal of the lesions and have not recurred.

CONCLUSION

Definite pathologic lesions may cause the superior oblique click syndrome.
