ABSTRACT

The case of 69 years-old woman, who went several times to the family physician's office because of the increased volume of her left breast, was presented. This problem was considered to result from the adverse effect of the spironolactone intake. The drug consumption ceased but there was no clinical improvement. Breast ultrasound test was indicated in which a tumor-like image below the breast tissue was observed; it seemed to be related to the major pectoralis muscle, additionally, there was altered breast pattern. Diagnostic mammography was performed, asymmetric volume of the left breast was found together with an increased density area located near the pectoralis, without viewing a defined nodule. Simple and contrast computerized tomography were also performed. It was observed that there was tumor mass in the left pectoralis major muscle infiltrating into the breast tissue and the anterior mediastinum, with imaging diagnosis suggestive of left pectoralis major muscle tumor. Ultrasound-guided fine-needle biopsy of the lesion was applied and the resulting diagnosis was infiltrating lobular carcinoma of the breast. It was concluded that the imaging result could be related to poor clinical manifestations and thus, to late diagnosis.
