Introduction: With increasing use of CT for a variety of diagnostic pathways, breast incidentalomas will be identified more frequently. Therefore, it is important for radiologists to know typical CT appearances of malignant and benign breast lesions. The aim of this study was to compare radiological features of benign and malignant incidental breast findings on CT reported in the literature. Methods: A search for appropriate studies published between 1988 and 2012 yielded five results with a total of 214 patients/257 lesions. Morphological features of the described breast masses, such as shape, margins, enhancement, axillary lymphadenopathy and calcifications, were analysed. Results: The prevalence of incidental breast carcinoma varied from 9.2% to 60.9% of the lesions. The frequency of benign lesions was 30.4–71.8%. The remaining incidental findings were intramammary metastases and primary or secondary breast lymphomas. Malignant lesions were larger in size, were round in shape and demonstrated a higher density compared with benign lesions. There was no significant difference in the margin characteristics of the masses between the groups. The morphological features previously postulated as typical for malignancy turned out to be non-specific. Conclusions: Benign and malign breast incidentalomas are not safely distinguished from each other on standard chest CT. Therefore, all breast incidentalomas should be evaluated by further radiological/histological investigations.

Intramammary incidental findings on staging computer tomography

There have been some reports of coincidental presentation of breast carcinoma and phyllodes tumor in the same breast. Most of the cases were carcinoma that arose from a phyllodes tumor with a histologically identified transitional area, and they behaved less aggressively than the usually encountered carcinoma. Collision tumors are rare clinical entities in which two histologically distinct tumor types show involvement at the same site. The occurrence of these tumors in the breast is extremely rare. Here, we report a case of 45-year-old woman who had both invasive ductal carcinoma as the finding of inflammatory carcinoma and a malignant phyllodes tumor in the same breast. There was no evidence of a transitional area between the phyllodes tumor and the invasive ductal carcinoma. To our knowledge, this is the first report of a collision tumor of inflammatory breast carcinoma coincident with a malignant phyllodes tumor in same breast.

Collision tumor with inflammatory breast carcinoma and malignant phyllodes tumor: a case report and literature review.

Leukemic involvement of the breast is rare, particularly involvement by chronic lymphocytic leukemia (CLL). While concurrent invasive ductal carcinoma and CLL manifesting as a collision tumor in the breast is extremely rare, this association (CLL and carcinoma) has been described in other organs. We report here a case of a 58-year-old woman with concurrent invasive ductal carcinoma and CLL and describe the imaging features of CLL, particularly the differentiation on MRI.

Collision tumors with synchronous presentation of breast carcinoma and lymphoproliferative disorders in the axillary nodes of patients with newly diagnosed breast cancer: a case series.

Collision tumors are rare clinical entities in which two histologically distinct tumor types show involvement in the same site. The occurrence of these tumors in the breast is extremely rare. Here, we present a case of a patient with both invasive ductal carcinoma and chronic lymphocytic leukemia in the breast. Wide excision with sentinel lymph node biopsy revealed palpably abnormal lymph nodes negative for breast carcinoma on frozen section. Histopathological examination of these lymph nodes showed extensive involvement by lymphoma and review of the breast specimen demonstrated the same lymphoma at the periphery of the ductal carcinoma. We review the literature and discuss possible etiologies for the dual presentation of both cancers.
