“…On the other hand, malignant features on breast sonography were irregular and round shape, non-parallel orientation, microlobulated, indistinct, angular, or spiculated margin, and boundary of echogenic halo (12)(13)(14)(15). There are several studies which reported the CT features of incidental breast lesions suggestive of malignancy, including irregular or spiculated mar- (16)(17)(18)(19). Similarly, in our study, malignant breast lesions were more irregular in shape and they demonstrated a non-circumscribed margin more frequently, compared with benign lesions (p = 0.023 and 0.031).…”

Purpose:To investigate the capability of enhanced chest computed tomography (CT) for detecting breast abnormalities and to assess the influence of breast composition on this detectability. Materials and Methods: From 2000 to 2013, 75 patients who underwent mammography, breast sonography, and enhanced chest CT within one month and had abnormalities on sonography were included. Detection rate of breast abnormality on enhanced chest CT was compared among 4 types of breast composition by the Breast Imaging Reporting and Data System. Contribution of breast composition, size and enhancement of target lesions to detectability of enhanced chest CT was assessed using logistic regression and chi-square test. Results: Of the 75 target lesions, 34 (45.3%) were detected on enhanced chest CT, corresponding with those on breast sonography; there were no significantly different detection rates among the 4 types of breast composition (p = 0.078). Breast composition [odds ratio (OR) = 1.07, p = 0.206] and enhancement (OR = 21.49, p = 0.998) had no significant effect, but size (OR = 1.23, p = 0.004) was a significant contributing factor influencing the detectability of enhanced chest CT for breast lesions. Conclusion: About half of the cases (45.3%) demonstrated breast lesions on chest CT corresponding with target lesions on sonography. Breast composition defined on mammography did not affect the detectability of enhanced chest CT for breast lesions. Index termsBreast Chest Multidetector Computed Tomography Ultrasound Mammography

Incidental Breast Lesions Detected on Computed Thorax Tomography

Objective: Although mammography is the primary imaging method of the breast, incidental benign and malignant breast lesions are increasingly being detected on computed tomographies (CTs) performed to detect different pathologies. Therefore, the detection and accurate identification of these lesions is important. In this study, we aimed to evaluate the frequency, morphological features, and results of incidental breast lesions on CTs performed for the detection of extramammarian pathologies. Materials and Methods:Incidental breast lesions on CTs performed in our department between 2011 and 2013 were evaluated. Patients who had previously diagnosed breast lesions were excluded from the study. The inclusion criteria were histopathologic diagnose and being followed -up for at least 2 years. Results:The study population consisted of 33 women whose mean age was 55±1.38 (37-78) years. Of the 33 women, 12 (36%) had malignant and 21 (64%) had benign or normal findings. The most common malignant lesion was invasive ductal carcinoma, and the most common benign lesion was fibroadenoma. Ill-defined contour and lymphadenopathy in malignant lesions and well-defined contour in benign lesions were the most important CT findings. Conclusion:Breast must be carefully evaluated if it is included in the scans. An accurate report of breast lesions gives an opportunity for early diagnosis and treatment. Keywords: Computed tomography, thorax, breast, incidental findings IntroductionCurrently, mammography, ultrasound and magnetic resonance imaging (MRI) are the basic radiologic methods to diagnose breast diseases. However, the widespread use of multislice computed tomography (CT) in the last decade increased the rate of incidentally detected breast lesions in return, although, it is not a primary breast imaging method. Especially new generation multi-slice CTs with high spatial resolution reveal structures and pathologies that could not be previously viewed in detail. With the widespread use of multislice CT scans and higher resolution, the rate of detecting incidental findings unrelated to the main disease is increasing. These incidental findings sometimes lead to unnecessary further investigations and follow-up that result in higher cost and anxiety (1). Another problem related to this issue is radiologists' being specialized according to the field of pathology. That is why, they may fail to identify pathologies outside this area. For example, when a radiologist specialized in chest CT evaluates the breast tissue within the cross-sectional area, she/he can misinterpret or overlook some abnormalities (2).It has previously been shown that CT may detect incidental breast lesions during pulmonary and cardiac imaging. There are studies describing the characteristics of breast lesions incidentally detected on CT. However, these studies are limited in number (3-8).The aim of this study was to assess the frequency, CT features and results of breast lesions that were referred to our clinic after being detected by CT scans obtained to in...

“…According to several reports, 24-32% of incidental breast lesions were subsequently proven to be malignant (3,7,8). Lin et al (4) reported that an irregular margin of incidental enhancing breast lesions can be suggestive of malignancy and a much higher rate (70%) of malignancy was demonstrated in lesions detected incidentally on CT scans.…”

“…Although many women participate in breast screening programs, multidetector computed tomography (MDCT) often provides the first images of the breast when patients undergo chest MDCT for evaluation of pulmonary or cardiac disease (1)(2)(3)(4). Since an MDCT scan provides improved contrast resolution, a larger field of view, and has cross sectional capability, breast lesions may be viewed more easily with a MDCT scan (1,5,6).…”
