Interventional radiology: The corner-stone of breast management

Histopathological Analysis of Vacuum-Assisted Breast Biopsy in Relation to Microcalcification Findings on Mammography: A Pictorial Review

Mammography is an essential tool in breast screening, often revealing lesions that appear as microcalcifications with or without an associated mass. Decisions about biopsy requirements are guided by the BI-RADS system, aiming to confirm the histopathology of suspicious lesions while avoiding unnecessary procedures. A vacuum-assisted breast biopsy (VABB) is a minimally invasive procedure for diagnosing breast abnormalities. Precise lesion targeting is ensured under stereotactic guidance, reducing the need for repeated procedures. Compared to traditional core needle biopsy (CNB) and fine-needle aspiration cytology (FNAC), it differs in using vacuum assistance to gather more tissue volume, increasing diagnostic accuracy and reducing the likelihood of histological underestimation. This is particularly crucial in cases where microcalcifications are the primary finding, as they are often the earliest signs of ductal carcinoma in situ (DCIS). Managing such findings requires precise diagnostic tools to differentiate benign from malignant lesions without subjecting patients to unnecessary surgical interventions. Building on several years of experience in our department, we have assembled a selection of ten interesting cases encountered in our clinical practice. Each case is documented with paired mammographic images and their corresponding image of histopathological findings, offering a comprehensive view of the diagnostic journey. These cases were selected for their educational value, highlighting the integration of imaging modalities, histopathological evaluation, and clinical decision-making. All cases underwent an extensive diagnostic workup at our facility. This compilation aims to provide valuable insights for both clinicians and researchers, offering a deeper understanding of advanced diagnostic techniques and their role in improving patient outcomes.

Can a breast hematoma lead to hemorrhagic shock in elderly trauma patients with multiple comorbidities and reduced physiological reserve? Examining the risks and management strategies

Breast trauma in elderly patients with multiple comorbidities can result in severe complications such as hemorrhagic shock due to the highly vascular nature of breast tissue. This case involves a 65-year-old female with a history of rheumatoid arthritis and prior breast cancer who developed a significant breast hematoma following a motor vehicle accident. Initially stable, she rapidly deteriorated with hypotension and altered mental status after imaging revealed a large hematoma with active hemorrhage. Immediate intervention, including blood transfusion and intubation, was essential for stabilization. While spontaneous cessation of bleeding and hematoma stabilization can negate the need for further intervention, persistent bleeding requires prompt action. Options include surgical exploration, hematoma evacuation, vessel ligation, interventional radiology for embolization, additional blood transfusions, and pharmacological hemostatic agents. Breast hematoma can lead to hemorrhagic shock if severe enough in elderly patients with reduced physiological reserve.

False-negatives due to poor specimens can be prevented based on the macroscopic findings for breast Vacuum-Assisted Biopsy specimens

PURPOSE

Ultrasound-guided breast tissue biopsy is an essential technique for diagnosing breast disease, but sample errors reduce its accuracy. This study investigated whether the histopathological results can be inferred from the macroscopic findings for Ultrasound-guided breast Vacuum Assisted Biopsy (VAB) specimens.

METHODS

Biopsy specimens from 101 patients who underwent mammary gland VAB were photographed with a smartphone, and the relationships between the macroscopic findings and the pathological results were examined.

RESULTS

A significant difference was observed with regard to the presence/absence of turbidity: malignancy was detected in 33/37 (89%) specimens with turbidity and in 2/47 (4%) cases without turbidity (p<0.001). A significant difference was also observed regarding the surface properties:malignancy was detected in 14/70 (19%) smooth specimens and in 24/29 (83%) rough specimens (p<0.001). Also, malignancy was detected in 11/13 (85%) specimens with white spots, and the difference was significant (p<0.001). In addition, the characteristics of intraductal papilloma, fibroadenoma, and mastopathy could be confirmed by macroscopic findings.

CONCLUSIONS

When needle-biopsy of a lesion that is targeted for resection yields macroscopic findings that match the predicted histopathological findings, it can be thought that the biopsy had been properly performed. This means that false-negatives due to poor specimens can be prevented. J. Med. Invest. 69 : 51-56, February, 2022.

Reducing Costs of Breast Examination: Ultrasound Performance and Inter-Observer Variability of Expert Radiologists Versus Residents

AIM

To compare efficiency levels between radiologist and radiology resident and any significant or clinically relevant differences in breast ultrasound diagnosis, thus reducing extra costs.

MATERIAL AND METHODS

100 patients attending for breast ultrasound were included. Each patient was examined by a radiologist, and subsequently by a resident of the radiology department. Both operators noted their findings and wrote a concluding report. Reports were compared for histological and biological analysis.

RESULTS

100 female patients with a mean age about 49 years were examined. The proportions of correct diagnoses of lesions individuated by radiologist and resident were 26.90 > 13.71% (p-value = 10.7), i.e. the radiologist was more accurate in comparison to resident in the individuation of breast lesions.

CONCLUSIONS

The radiologist was more accurate in comparison to radiology resident in the evaluation of breast pathology in ultrasonography diagnoses, and this could reduce cost and/or in-depth analysis.

MRI vacuum-assisted breast biopsies

The indications, technique, results and limitations of MRI vacuum-assisted breast biopsies are discussed from a review of the literature. This was initially a home-grown technique and its development was slowed down by several factors. As a result of major technical advances, it has become a reliable and very consistent procedure with a low rate of underestimation. It is now an undisputed technique when suspicious MRI enhancement is seen with no corresponding mammography or ultrasound features.
