Role of mammography in diagnosis of axillary abnormalities in women with normal breast examination
The mammograms of 43 patients presenting with palpable unilateral masses in the axilla and normal breasts on physical examination were retrospectively reviewed to determine the cause and imaging characteristics of axillary abnormalities, and the usefulness of mammography in detecting occult breast c...

| Summary: | The mammograms of 43 patients presenting with palpable unilateral masses in the axilla and normal breasts on physical examination were retrospectively reviewed to determine the cause and imaging characteristics of axillary abnormalities, and the usefulness of mammography in detecting occult breast carcinoma. Cytological or histological confirmation was obtained in all patients. Forty of 43 patients had axillary lymphadenopathy while three had lipoma, f ibroadenoma and haematoma, respectively. Causes of malignant lymphadenopathy (n = 22) were metastatic diseases from non-mammary primary malignancy (n = 8), occult ipsilateral breast carcinoma (n = 5), and previous contralateral breast carcinoma (n = 9). Causes of benign lymphadenopathy (n = 18) were reactive nodal hyperplasia (n = 6), collagen vascular diseases (n = 2), and acute bacterial (n = 2) and tuberculous (n = 8) lymphadenitis. Nodal size was not significantly different between benign and malignant lymph nodes. Benign and malignant nodal margins were variable. Intranodal microcalcifications were found in two cases of breast carcinoma mestastasis. Intranodal macrocalcifications were found in three cases of tuberculous lymphadenitis. Occult primary breast carcinoma was detected on mammograms in four of five patients with axillary lymphadenopathy due to ipsilateral breast carcinoma. Mammographical features of benign and malignant lymphadenopathy may be indistinguishable, but presence of intranodal calcifications is helpful. Mammography is also valuable in depicting occult primary breast carcinoma. |
