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


METHODS
Two observational case reports.


METHODS
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.


METHODS
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.


CONCLUSIONS
Definite pathologic lesions may cause the superior oblique click syndrome.
