PURPOSE: The aim of this study is to determine the impact of a simulation-based ultrasound-guided (USG) breast biopsy training session on radiology trainee procedural knowledge, comfort levels, and overall procedural confidence and anxiety. METHODS: Twenty-one diagnostic radiology residents from a single academic institution were recruited to participate in an USG breast biopsy training session. The residents filled out a questionnaire before and after the training session. Ten multiple-choice questions tested general knowledge in diagnostic breast ultrasound and USG breast biopsy concepts. Subjective comfort levels with ultrasound machine and biopsy device functionality, patient positioning, proper biopsy technique, image documentation, needle safety and overall procedural confidence and anxiety levels were reported on a 5-point Likert scale before and after training. RESULTS: Participants demonstrated significant improvement in number of correctly answered general knowledge questions after training (P < .0001). Significant improvement was seen in resident comfort level in ultrasound machine functionality, patient positioning, biopsy device functionality, biopsy technique, image documentation, as well as overall confidence level (all P < .05). Participants indicated a slight but not significant reduction in anxiety levels (P = .27). CONCLUSIONS: A simulation-based USG breast biopsy training session may improve radiology trainee procedural knowledge, comfort levels, and overall procedural confidence.

PURPOSE: The utilization of staging preoperative breast MRI in biopsy-proven cancer patients varies based on institution and individual clinicians. It is unclear whether primary breast cancer subtype influences a clinician's decision to obtain a preoperative breast MRI based on likelihood of multicentric or contralateral disease, which may change surgical or medical management. Our purpose was to compare the four main breast cancer subtypes in our patient population (i.e., luminal A, luminal B, HER2 enriched and triple-negative) who underwent pretreatment staging MRIs to determine whether certain breast cancer subtypes are more likely to have multicentric or contralateral disease. METHODS: We retrospectively reviewed 435 patients with biopsy-proven invasive breast cancer who had staging MRI. RESULTS: Of these patients, 14 had biopsy-proven multicentric disease (3.2% of total) and 15 had biopsy-proven contralateral second tumor sites (3.4% of total). There was no statistically significant difference between primary tumor subtype and likelihood of multicentric or contralateral disease (p = 0.3065). CONCLUSION: Pretreatment staging MRI can detect multicentric and/or contralateral additional tumor sites, which ultimately changes staging, treatment options, and outcomes for patients with biopsy-proven breast cancer. There is no correlation between primary breast cancer subtype and likelihood of multicentric or contralateral disease.

Granulomatous mastitis is a rare and benign inflammatory condition of the breast most commonly affecting women of child-bearing age as well as patients on oral contraceptives. This condition is important to identify due to its diagnostic mimicry of malicious entities such as breast carcinoma. Clinical and radiological findings are nonspecific and may overlap with breast carcinomas, thus pathologic confirmation is often necessary for definitive diagnosis. Although cases of granulomatous mastitis have been described in cisgender females, there have been no reported cases in the transgender patient, a growing patient population with few imaging guidelines. Transgender patients are at risk of developing this breast entity due to the use of long-term hormone treatments or presence of residual breast tissue. A trial of antibiotics or steroids may be administered. However, surgical treatment is often necessary in recurrent or refractory cases.
