EVALUATION OF CONGENITAL BROWNS SYNDROME WITH MAGNETIC-RESONANCE-IMAGING

The magnetic resonance (MR) findings in congenital Brown's syndrome we re investigated. Sixteen involved eyes of 12 patients were compared wi th 20 eyes of 10 controls, An enlargement of the tendon-trochlea compl ex was observed in congenital Brown's syndrome. In addition, the appea rance of the tendon-trochlea complex was irregular in shape and of int ermediate signal intensity. The MR appearances in patients with a sati sfactory or poor response to surgery did not show any significant diff erences from each other or from those in patients who had not undergon e surgery. This was also the case for the patient with spontaneous imp rovement, The MR examination in congenital Brown's syndrome suggested that the abnormality was located at the tendon-trochlea complex but cl inically it does not give a clue about the outcome of the disease.
