[μλ¬Έ]The purpose of this study was to evaluate the variable causes of symptomatic palpable axillary masses and their imaging findings. Pathologically confirmed thirty-three masses of 31 women(mean age 45 years) were evaluated in the incidence and imaging findings. All cases underwent either mammography(n=26), sonography(n=28), or magnetic resonance imaging(n=4). The prevalent symptomatic palpable axillary masses were tuberculous lymphadenitis(n=13), followed by accessory breast related lesions(n=8), malignant(n=5) and benign(n=4) primary masses, and metastastic lymphadenopathy(n=3).
Lymph node related masses were mainly multiple lesions and the other primary masses tended to be single lesion. The primary axillary tumors other than lymph node origin presented as larger in size(>=5cm) with variable density. Typical density of fat and accessory breast was important clue to the final diagnosis. The location of the masses were one of the differential point. It was difficult to differentiate the benign and malignant lymphadenopathy, however dense benign calcifications in the masses were the possible predictors for tuberculous lymphadenitis.
Knowledge of variable axillary masses and their incidence and imaging findings will help to differentiate and diagnose the symptomatic palpable axillary lesions.ope
