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.
"To characterize such masses (Cady et al., 1998) and is 100% accurate in diagnosis of a cyst (Pak-art et al, 2004). Pak-art et al. (2004) also found that the commonest positive findings were cysts. The mean age of patients with "
[Show abstract][Hide abstract] 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.

Of the six histology reports obtained, 3 (1%) were confirmed malignant, 2 (0.7%) were not malignant and one (0.3 %) was a fibrocystic disease. We found out that most masses seen were benign, although 33.3% of suspected cancer picked up on mammography was confirmed malignant. Also, microcalcifications were a strong indicator of malignancy in this study.
[Show abstract][Hide abstract] ABSTRACT: The advent of newer imaging techniques has necessitated the need for us to evaluate the distribution pattern of common and significant imaging findings on mammography at the Lagos state University Teaching Hospital. A retrospective study on all the 300 patients referred to the radiology department of LASUTH from August 2003 to August 2006 for mammography was carried out and the imaging findings were recorded using the American College of Radiology (ACR) Breast Imaging Reporting and Data System (BIRAD) classification method to assess mammographic density. However, ultrasound scans were done in patients less than 35 years of age who had a mass. The mammography images result revealed that majority of the breasts, about 39 (13%) were mainly fatty, 11 (3.7 %) were glandular, whereas, 3 (1%) were mainly fibrous. However, 149 (49.7%) were mixed (fibro-fatty) and 98 (32.7%) dense in nature. Using the BIRAD classification, 41 (13.7 %) patients were classified as Birad 1 whereas the majority of the cases seen, 154 (51.3 %) were classified as Birad 2, while 57 (19%) and 48 (16%) were categorized into Birad 3 and 4, respectively. However, mammographic findings were normal in 164 (54.7%) patients seen. Various types of calcifications were seen in 87 (29%) of patients. Of these, 22 (7.3 %) were microcalcifications. However, two of the confirmed malignant masses had microcalcifications and dilated ducts were seen in 3 (1%) patients. The nipple was tethered and inverted in 3 (1%) patients, skin thickening was seen in 3 (1%) patients, widened subcutaneous tissue in 3 (1%), scar in 2 (%). One (0.3%) patient had postsurgical clips, while skin fold was seen in one (0.3%). Of the six histology reports obtained, 3 (1%) were confirmed malignant, 2 (0.7%) were not malignant and one (0.3 %) was a fibrocystic disease. We found out that most masses seen were benign, although 33.3% of suspected cancer picked up on mammography was confirmed malignant. Also, microcalcifications were a strong indicator of malignancy in this study.
