Oil cysts are benign breast masses. Mammographically, oil cysts typically appear as well defined, round or ovoid masses, often with a calcified rim (eggshell calcification).
Sonographically, oil cysts may present in a variety of ways. Most cysts are anechoic or hypoechoic with a variable degree of posterior shadowing or acustic enhancement with a thin capsule. However, oil cysts presenting with mural nodules may rarely mimic intracystic neoplasm and ultrasound cannot characterize the masses as benign.
Mammograms which demonstrate the fatty content are diagnostic.

For carcinoma specimens with non-grossly identifiable lesions such as microcalcifications, difficulties may be encountered in locating these abnormalities and sampling the margins that are at risk. This is magnified in the case of skin-sparing procedures where the margin is a much greater surface area and is the operation of choice in patients with diffuse microcalcifications and/or multifocal in situ disease. The objective of this study was to determine the efficacy of specimen radiographs of mastectomy in identifying occult carcinoma associated with microcalcifications and assessing the resection margins.
The average number of tissue blocks sampled among randomly selected mastectomy specimens was 15.2 ± 5.4. There was no statistically significant difference in the number of blocks between mastectomy cases with specimen radiographs taken and those without (t-test). Our study suggests that specimen radiographs may assist in identifying occult breast carcinoma associated with microcalcifications and assessing the resection margins without increased sampling

Breast hamartomas are rare in the adolescent population. The clinical and radiographic features are similar to the more common fibroadenoma, but the pathologic findings are diagnostic. Recurrence can occur if excision is incomplete.
Increased recognition and accurate diagnosis will improve our understanding of the natural history of these lesions

Use of Ultrasound-Guided Percutaneous Vacuum-Assisted Breast Biopsy for Selected Difficult Indications
Use of Ultrasound-Guided Percutaneous Vacuum-Assisted Breast Biopsy for Selected Difficult Indications

To assess ultrasound-guided vacuum-assisted biopsy (US-VAB) for selected problem cases and to report experiences with two different biopsy systems. Fifty-one lesions have been biopsied using the Mammotome (n = 24) or the Vacora (n = 27) system.
Main indications: lesion in scarring (n = 5), complex cystic ≥8 mm (n = 7), increase in size (n = 10), architectural distortion (n = 4), uncharacteristic palpable abnormality (2), small size (n = 22), regional microcalcifications (n = 1). Results are verified by surgical excision (n = 10) or follow-up (n = 40). One patient was lost to follow-up. In four of the cases preceding core biopsy was inconclusive. four invasive carcinomas, two ductal carcinoma in situ (DCIS), three papillomas, six fibroadenomas, one adenosis tumor, one hamartoma, 10 complex cysts, 16 benign changes, three fat necroses, two granulomas, three unspecific inflammatory changes are verified.
Surgery confirmed five malignancies, four benign changes, and converted one uncertain diagnosis (architectural distortion) from "inflammatory" to DCIS. Documented removal of all or most of the lesions correctly increased the level of confidence and open surgery could be avoided in 41/51 lesions.
The two systems show different advantages and drawbacks. US-VAB may improve the level of confidence in selected difficult cases. Careful case selection and systematic retrospective correlation of imaging and histology remain crucial

Correlation between Quantified Breast Densities from Digital Mammography and 18F-FDG PET Uptake
Correlation between Quantified Breast Densities from Digital Mammography and 18F-FDG PET Uptake

To correlate breast density quantified from digital mammograms with mean and maximum standardized uptake values (SUVs) from positron emission tomography (PET). This was a prospective study that included 56 women with a history of suspicion of breast cancer (mean age 49.2 ± 9.3 years), who underwent 18F-fluoro-2-deoxyglucose (FDG)-PET imaging of their breasts as well as digital mammography. A computer thresholding algorithm was applied to the contralateral nonmalignant breasts to quantitatively estimate the breast density on digital mammograms. The breasts were also classified into one of four Breast Imaging Reporting and Data System categories for density.
Comparisons between SUV and breast density were made using linear regression and the Student's t-test. Linear regression of mean SUV versus average breast density showed a positive relationship with a Pearson's correlation coefficient of R2 = 0.83. The quantified breast densities and mean SUVs were significantly greater for mammographically dense than nondense breasts
The average quantified densities and mean SUVs of the breasts were significantly greater for premenopausal than postmenopausal patients
Menopausal status affects the metabolic activity of normal breast tissue, resulting in higher SUVs in pre- versus postmenopausal patients
