In every breast imaging, the radiologist confronts these questions:%26quot;n1. Finding the lesion%26quot;n2. Is the lesion real?%26quot;n3. Where the pathology lies%26quot;n4. What the lesion is %26quot;n5. What should be done about it?%26quot;nThe major objective in breast imaging is the detection of breast cancers at a small size and early stage in an effort to reduce mortality.%26quot;nSome conditions limit evaluation of breast cancer imaging.%26quot;nWhen additional mammographic views or ultrasound are unable to triangulate the location of a lesion, computed tomography can be very helpful for locating lesions three dimensionally. MRI with and without contrast is the other modality for evaluation of problematic cases or ambiguous findings in other modalities.%26quot;nImplants present a problem for breast imaging in that they may prevent optimal visualization of the tissues.%26quot;nA focal asymmetric density may merely represent an island of breast tissue. DCIS, with or without calcification, and metastatic axillary lymph nodes in a normal mammogram are some of the problematic cases of breast cancer.%26quot;nThis presentation is expected to include real cases of breast cancer with the above-mentioned problems or unusual manifestations, which are resolved by a combination of different imaging modalities.
