Abstract

To describe the clinical features in two patients with superior oblique click syndrome and the pathologic causes of their symptoms. Two observational case reports. Two patients. 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. Relief of symptoms. 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. Definite pathologic lesions may cause the superior oblique click syndrome.
