Breast lesion incidentally detected with chest CT

Androniki Kozana, Emmanouil Mastorakis, Gerardina Cavallo


A 76-year-old female patient was admitted in our hospital with acute cholangitis. Owing to prolonged fever and negative chest X-ray, a chest CT was requested three days later. Chest CT was performed according to our department’s standard protocol (Fig. 1).

An incidental finding was an enhancing, irregular mass lesion of the left breast. The lesion was characterized as sufficiently suspicious to warrant dedicated diagnostic work-up. Ultrasonographic examination and cytopathology are shown on Fig. 2 and Fig. 3 respectively.
