INTRODUCTION: We report the preliminary results of a study on the importance of juxtajugular and supraisthmian lymph node enlargement at US as a sign of occult @entity4941 . MATERIAL AND METHODS: We examined @entity1 submitted to thyroid US for noninflammatory thyroid conditions and for positive familiarity and studied the presence of supraisthmian and juxtajugular lymph node enlargement. The @entity1 were then divided into two groups: the clinical history, antibody titer and symptoms were studied in group A ( @entity1 with enlarged lymph nodes) and the antibody titer, symptoms and US findings were studied in group B ( @entity1 with a history of @entity1374 ). RESULTS: Fifty-nine of 600 @entity1 were allocated to group A and 25 of 600 to group B. Of the former 59 asymptomatic @entity1 (10% of the total), 29% had supraisthmian and 85% juxtajugular lymph node enlargement, with some @entity1 positive at both sites. Forty-seven @entity1 (80%) had @entity4941 (33 of them with positive antibodies and 23 with a clinical history); we had 12 false positives. Twenty-two of 25 group B @entity1 (91%) had supraisthmian (40%) or juxtajugular (83%) lymph node enlargement: 3 @entity1 with no enlarged lymph nodes had an over 3-year history of low antibody titers. DISCUSSION: Forty-seven of 600 (8%) asymptomatic @entity1 who had been never examined are or were affected with @entity4941 . Ninety-one per cent of all @entity1374 @entity1 had supraisthmian or juxtajugular lymph node enlargement, more frequently the latter than the former. CONCLUSIONS: Supraisthmian and/or juxtajugular lymph node enlargement appears to be a very useful US sign of @entity4941 , even though these data need confirmation from larger series of @entity1 .
