Breast Mass: Standard cranio-caudal and medio-lateral oblique mammographic images demonstrate marked breast atrophy, more notable on the left side.

Ductal Adenocarcinoma of the Breast: 50-year-old white female, placed on hormone therapy. Question of left breast fullness, with two palpable left axillary lymph nodes. Only a simple cyst seen on mammography - confirmed by ultrasound. However, MR showed enhancing focal mass with additional diffuse infiltration in a patient with negative mammogram.

Ductal Carcinoma In Situ (DCIS), Comedo Subtype: In the superolateral aspect of the right breast, there is a 3 x 3 cm area of extensive branching pleomorphic calcifications. Additional benign dystrophic and vascular calcifications are also present.

Ductal Carcinoma In Situ: The mammogram demonstrates multiple minute pleomorphic calcifications scattered throughout the left breast, predominantly in the central inferior aspect. The findings are highly suspicious for malignancy.

Extravasated Silicone: The right mammogram demonstrates a subpectoral silicone implant. There is an extensive amount of high density material in the axilla consistent with globules of extravasated silicone.

Granular Cell Tumor of the Breast: 47-year-old female with palpable mass in the left breast x three months. Mammogram showed spiculated mass identified in the upper outer quadrant of the left breast with associated architectural distortion corresponding to palpable abnormality. Pathology showed granular cell tumor of the breast.

Hamartoma of the Breast: The left breast is enlarged secondary to an enormous mass of mixed density, displacing normal breast parenchyma to the superolateral aspect of the breast.

Infiltrating Ductal Carcinoma: The mammogram demonstrates a 1.5 cm. rounded mass with spiculated margins and a small "comet tail" in the central inferior aspect of the right breast. No associated calcifications are seen.

Infiltrating Ductal Carcinoma of the Breast: Retrospectively, a dominant mass with spiculation can be recognized on the study of 6/26/91, with gradual increase in size and density. Although the mammogram of 5/16/94 was incorrectly read as no evidence of malignancy, the new palpability of the lesion should have prompted biopsy.

Inflammatory Carcinoma: A biopsy of this woman's right breast following the 8-21-95 mammogram revealed invasive ductal carcinoma, inflammatory type. Dermal lymphatic invasion was prominent.

Intracystic Papillary Carcinoma: The mammogram shows a 3 x 2.5 cm lobulated, circumscribed mass in the right breast. The breasts are otherwise mostly fat replaced. To ensure that the radiographic finding corresponded to the palpable abnormality, a metallic BB was placed in the region of palpable abnormality.

Lipoma: In the central inferior aspect of the left breast, there is a 10.5 x 11.0 cm fatty mass partially circumscribed by a thin capsule. Three calcifications of fat necrosis are associated with it. The mass displaces the adjacent parenchyma superiorly and laterally.

Medullary Carcinoma: Bilateral mammograms obtained show a 1.7 cm lobulated mass in the superior aspect of the left breast on the MLO view only.
Microlobulated Ductal Carcinoma In Situ: There is in the central and slightly superior aspect of the left breast a 1.5 cm mass that correlates with a clinically palpable finding. The margins are microlobulated suggesting a high suspicion for malignancy. There are no associated microcalcifications.

Multifocal Ductal Carcinoma of the Breast: Multifocal ductal carcinoma in situ, micropapillary and cribriform types - low grade. Focal lobular carcinoma in situ. Fibrocystic disease with atypical ductal epithelial hyperplasia and papillomatosis.

Radial Scar: In the superolateral aspect of the right breast, there is a 3 cm area of architectural distortion with peripheral spiculation and central lucency. There are no suspicious calcifications associated with it. The finding is optimally visualized on the craniocaudal and true lateral views.

Radial Sclerosing Lesion: A small irregular density with subtle architectural distortion is present on the craniocaudal view in the medial left breast. A diagnostic mammogram (repeat views with spot magnification) confirms the presence of a 7 x 5 mm irregular mass with architectural distortion in the inner central left breast.

Sclerosing Adenosis: An excisional breast biopsy revealed sclerosing adenosis, with florid ductal hyperplasia. No malignancy was found.
