Abstract
In this study, the patients were classified into three groups, thenormal control group (Group I) the non-malignant group (Group II) andthe malignant group (Group III), according to the size and features of thedetected lymph nodes.In group (I), which includes 5 patients, the largest diameter of the lymph nodes detected by mammography in the right axilla ranged from 10 to 12 mm, while in the left axilla the largest diameter ranged from 11 to 13 mm. In group (II), which includes 22 patients, the largest diameter of the lymph nodes detected by mammography in the right axilla ranged from 8 to 27mm, while on the left side the largest diameter ranged from 9 to 18 mm, (mean = 13±2.8 mm). In group (III), which includes 38 patients, the size of lymph nodes detected in the right axilla ranged from 14 to 34 mm (mean = 25.7±5.9 mm), while on the left side it ranged from l0 to 55mm (mean == 28.8±11.2 mm).In general, the diameter of the lymph nodes measured by sonography was less than that measured by mammography by 1-2 mm due to magnification.The common benign causes of axillary adenopathy include dermal< infections (both of the hand and breasts), rheumatoid arthritis and less common arthritides such as psoriasis, systemic lupus erythematosus and< scleroderma. Enlarged axillary nodes may also occur as part of the generalized adenopathy seen in sarciod In this study the benign causes of adenopathy were fibroadenosisr (50.0%), reactive hyperplesia (18.2%), fibro adenoma, mastitis and impetigo (9.1 %) and fibrocystic disease (4.5%).The hilum was preserved in 77.3%, and absent in 22.7% of these patients.
