There was no history of breast pain, cyclical lumpiness, axillary lump or nipple discharge. There was no medical history, family history or social history of significance. On examination, the patient had a 2×2 cm firm, non-tender, mobile lump in the upper and outer quadrant of the right breast, with normal overlying skin. Nipple areola complex and axillary examination were normal. Opposite breast, axilla and supraclavicular examination was normal. A mammogram (figure 1) and ultrasonography (figure 2) of the right breast were performed to delineate the underlying characteristics of the lump. The findings were suggestive of cysticercosis of the breast and the patient was treated with albendazole 400 mg twice daily for 15 days. She responded favourably, with the lump decreasing to 1×1 cm. Chest X-ray, ultrasonography of the abdomen and non-contrast CT of the head were carried out to exclude cysticercosis in those areas. All the above investigations were normal. Fine-needle aspiration cytology (FNAC) was inconclusive. Cysticercosis of the breast may mimic a fibroadenoma, or a breast malignancy.
