Abnormal findings in breast imaging: a hospital-based survey in 4264 Thai women.
ABSTRACT To evaluate the distributions of common and significant imaging findings from breast imagings at King Chulalongkorn Memorial Hospitals.
Data was collected from every mammography performed from November 1, 2001 to October 31, 2002. The reports were analyzed and imaging findings were recorded. The ACR BI-RADS category was applied to all cases.
There were 4264 patients and all of them were female. The age range was between 19-90 years and average age was 50.1 years. The most common positive findings were cysts (39.22%), followed by focal lesions (14.76%), mass (8.69%), architectural distortion (7.83%), calcification (7.36%) and thick ducts (3.76%). According to ACR BI-RADS, most of the studies were in category 2 (42.59%), followed by category 1 (38.67%), category 3 (12.08%) category 5 (3.45%), category 4 (3.12%) and category 0 (0.09%).
Breast imaging is the standard screening tool for breast cancer and can reveal different kinds of findings. Knowing the distribution of these findings helps both the radiologists to understand the scope of their work and the institution to audit their practice.

ABSTRACT: The number of mammography examinations done in Nigerian hospitals has increased tremendously over the last three years, due to the breast cancer awareness of the general populace, recent acquisition of mammography machines and attempts at setting up national breast screening programmes. Mammography plays an extremely important role in the diagnostic assessment and screening of breast cancer. There has however been no documentation of mammographic findings in our environment to serve as guide for practitioners. An appreciation of non-pathological findings in relation to abnormal findings is needed to avoid the practice of unnecessary and sometimes aggressive procedures. This study was undertaken to analyze and document the significant mammographic findings in a new tertiary institution over the last three years. Three hundred consecutive patients sent for screening and diagnostic mammography had their mammograms reviewed. Significant findings were recorded and compared to histopathological and ultrasound findings. The various types of breast density found included fatty, dense, fibrofatty and fibroglandular breast. The pathologies found ranged from masses (cysts, fibroadenoma and cancer), dilated ducts, skin thickening or tethering, keloids, surgical clips, and calcifications to microcalcifications. This pictorial essay describes and illustrates the mammographic appearances of normal variants and various pathologies elicited in 300 consecutive patients seen in this radiology department.
