“…For ILC, the differentiation features may include multifocality, difficulty of clinical detection, posterior acoustic shadow and isodensity or hypodensity[19]. For IDC-NOS, spiculate margins are a key feature[20], whereas this feature was not prominent in the NEBCs in this study. Nevertheless, in this study, with a limited number of cases, NEBC did not show a specific appearance that could distinguish it from other types of breast cancers.…”

This study aimed to determine and quantitate the mammographic and sonographic characteristics in 13 cases of solid neuroendocrine breast carcinoma (NEBC) and to analyze the association of radiological findings with the clinical and histopathologic findings. The clinical data and imaging findings of 13 female patients with histologically confirmed solid NEBC were reviewed. Imaging data were evaluated by two radiologists for a consensual diagnosis. All patients presented with one palpable mass; only 1 experienced occasional breast pain, and 5 complained of fluid discharge. In 7 patients, the masses were firm and mobile. Regional lymph node metastasis was noted in only 1 patient. For the 10 patients who underwent mammography, 6 had a mass, 1 had clustered small nodules with clustered punctuate microcalcifications, 2 had asymmetric focal density, and 1 had solitary punctuate calcification. Most of the masses had irregular shape with indistinct or microlobulated margins. For the 9 patients who underwent ultrasonography (US), 9 masses were depicted, all of which were hypoechoic, mostly with irregular shape and without acoustic phenomena. Different types of acoustic phenomena were also identified. One patient had developed distant metastases during follow-up. NEBC has a variety of presentations, but it is mostly observed on mammograms as a dense, irregular mass with indistinct or microlobulated margins. Sonographically, it typically presents as an irregular, heterogeneously hypoechoic mass with normal sound transmission. Histories of nipple discharge and calcification observed using imaging are not rare.

“…Asymmetry corresponds to 1-14% of ILC cases identified by mammography [10]. Mammographic normal findings and mass lesions are more common in ILC than in IDC [8]. Suspicious microcalcifications are uncommon in ILC [11].…”

“…ILC is more likely to be diagnosed in older women, tends to be larger, more bilateral [2,3] and multifocal [8] than IDC. The growth of ILC is characterized by infiltration of the stroma and surrounding breast tissue without destruction of anatomic structures or elicitation of substantial connective tissue response [9].…”

We present a case of a 72-year-old woman referred to the breast disorder service due to abnormalities on mammography and breast ultrasound. The patient reported using different hormone therapy (HT) formulations during 25 years and had stopped taking HT for 4 years. Physical examination showed no alterations in the breasts or axilla. Mammography from 2012 detected asymmetry at the 3 o'clock position in the anterior right breast. Ultrasound revealed an irregular, hypoechoic mass with indistinct margins, and posterior acoustic shadowing. A retrospective analysis of mammographies from 2007, 2009 and 2010 showed that a very subtle asymmetry had existed since 2007. Follow-up imaging demonstrated no change in asymmetry during 4.5 years. The patient underwent breast-conserving therapy and sentinel lymph node biopsy. Histopathologic examination demonstrated classic invasive lobular carcinoma. There were no sentinel node metastases. The patient received radiotherapy and endrocrine therapy. This case demonstrates that breast cancer may remain stable and not grow for many years. This aspect should be kept in mind by all professionals dealing with women's healthcare, in particular HT users who may develop breast cancer with a less aggressive behavior. Any suspicious finding on mammography, despite being unchanged for a number of years, must be investigated.

“…Because of its infiltrative growth pattern and tumor cells arranged in single file cells, ILC may be subtle or occult on mammography [9][10][11][12]. Reported rates of multifocal and multicentric disease are higher for ILC than for invasive ductal cancer [13][14][15][16][17]. Sonographic sensitivity for ILC is higher than that of mammography, with reported ultrasound sensitivities ranging from 68% to 98% [5,15,16,18,19].…”

Imaging features of invasive lobular carcinoma: comparison with invasive ductal carcinoma

Abstract: Normal findings, mass lesions on mammography, and posterior acoustic shadowing on US were more frequently associated with ILCs than with IDCs. Multifocality was more prevalent with ILCs than with IDCs.
