Lymphoepithelioma-like carcinoma of the breast presenting as breast abscess.

Lymphoepithelioma-like carcinoma (LELC) is a rare type of neoplasm in which only twenty cases have been reported in the breast. This type of tumor can be difficult to distinguish from other breast tumors particularly medullary carcinoma and lymphoma in the breast. We present a case of LELC of the breast presenting as an abscess along with a review of the literature.

Performance characteristics of ultrasound-guided fine-needle aspiration of axillary lymph nodes for metastatic breast cancer employing rapid on-site evaluation of adequacy: analysis of 136 cases and review of the literature.

Background: It has been demonstrated that axillary ultrasound-guided fine-needle aspiration (US-FNA) has excellent positive predictive value for the axillary lymph node status of patients with breast cancer before surgery or neoadjuvant therapy and, thus, can obviate the need for sentinel lymph node biopsy in FNA-positive patients. However, US-FNA has only moderate sensitivity, in part because of the collection of nondiagnostic or equivocal specimens. Rapid on-site evaluation for adequacy (ROSE) can improve definitive diagnosis rates but has not been well characterized in this setting.

Cystic lesions of the breast: sonographic-pathologic correlation.

Purpose: To understand the pathologic basis for sonographic features of cystic lesions of the breast and determine appropriate assessment and management recommendations for these lesions based on sonographic appearance.

Materials And Methods: From a database of 2,072 image-guided procedures performed from July 1995 through September 2001, 150 cystic lesions were identified. Diagnosis was established with fine-needle aspiration (n = 55), 14-gauge core-needle biopsy (n = 81), or both (n = 14).

Breast Imaging Reporting and Data System: inter- and intraobserver variability in feature analysis and final assessment.

Objective: We sought to evaluate the use of the Breast Imaging Reporting and Data System (BI-RADS) standardized mammography lexicon among and within observers and to distinguish variability in feature analysis from variability in lesion management.

Materials And Methods: Five experienced mammographers, not specifically trained in BI-RADS, used the lexicon to describe and assess 103 screening mammograms, including 30 (29%) showing cancer, and a subset of 86 mammograms with diagnostic evaluation, including 23 (27%) showing cancer. A subset of 13 screening mammograms (two with malignant findings, 11 with diagnostic evaluation) were rereviewed by each observer 2 months later.

Predictive value of specimen radiography for core needle biopsy of noncalcified breast masses.

Objective: Our objective was to determine the predictive value of specimen radiography for large core (14-gauge) needle biopsy of noncalcified breast masses.

Subjects And Methods: Eighty-four biopsies of 83 breast masses yielded 403 specimens. Specimens showing dense material on specimen radiography were predicted to be diagnostic; specimens showing intermediate- or low-density material were predicted to be nondiagnostic.

Evaluation of 14- and 11-gauge directional, vacuum-assisted biopsy probes and 14-gauge biopsy guns in a breast parenchymal model.

Purpose: To compare commercially available 14-guage core biopsy guns and 11- and 14-gauge, directional, vaccum-assisted biopsy probes for tissue yield and fragmentation.

Materials And Methods: One hundred passes were made through fresh turkey breasts by using each of 11 14-gauge, automated biopsy gun-needle combinations and a directional, stereotactic, vacuum-assisted biopsy system equipped with 11- or 14-gauge probes. Specimens were measured for total weight, individual length, diameter, and number of fragments.

Large-core biopsy guns: comparison for yield of breast tissue.

Purpose: To compare seven large-core, long-throw, 14-gauge biopsy guns for yield and quality of breast tissue obtained.

Materials And Methods: A two-phase, randomized and blinded study was performed. In the first phase, four fully automated 14-gauge biopsy guns (BIP, Manan, Biopsy, and ASAP) and one semiautomated device (Temno) were used to obtain breast cores from a cadaver.

[The radiological assessment of the knee in the meniscectomy patient].

The increasing number of radiologic examinations performed on patients previously submitted to arthroscopic meniscectomy led us to analyze the types of lesion most frequently found in these patients and the prognostic factors related to meniscectomy. Thus, the radiographs, CT and MR examinations were reviewed of 34 symptomatic patients submitted to arthroscopy at least 1 year earlier and in whom symptoms had appeared no more than 3 months earlier, thus ruling out the symptoms related to surgical complications. Lesions were found in the menisci, in the meniscal stumps and in the articular ends.

[Reconstruction of the anterior cruciate ligament with patellar tendon. Comparison between magnetic resonance and computerized tomography].

CT and MR potentials were compared in 30 patients submitted to anterior cruciate ligament reconstruction using the patellar tendon. In each patient the clinical data were correlated with the following radiologic parameters: the course of the tibial and femoral tunnels, their intraarticular outlet sites and their shape, the shape of the intercondylar notch and of the medial wall of the lateral femoral condyle and, finally, the shape of the graft and of the synovia. The intraarticular outlet site of the tibial tunnel was studied on the sagittal or transverse planes.

[The Achilles tendon: echography at different frequencies. Comparative study].

The authors report their experience with a comparative US study employing different-frequency probes (7.5, 10, 13 and 15 MHz) in Achilles tendon conditions. The study population included 49 patients, 37 of them athletes.

[Hemophilic arthropathy: echography and radiology].

Our experience is reported with the combined use of radiology and US in the study of 210 joints of hemophilic patients. The study was carried out considering that in hemophilia the classification of the grades of disease generally relies upon X-ray findings which, although reliable in the advanced stages of the disease, appear inadequate in the early stages. In fact, synovial hypertrophy, cartilage erosions and initial subchondral cysts are most often missed on X-ray films.

[The diagnostic imaging of complex breast nodules].

This study was aimed at determining the role of high-frequency (7.5 MHz) US combined with cytology in the diagnosis of complex breast nodules (complex cysts--cystic tumors). The study population included 60 patients presenting with complex breast nodules selected on the basis of US patterns among 3,000 cases.

[Echography in gynecologic emergencies].

The authors report their experience with US in gynecologic emergencies through a retrospective study on 105 patients presenting with acute abdomen of suspected gynecologic nature. The series included 3 groups of patients: Group I: 59 patients all submitted to immediate surgery. The following pathologic conditions were observed: ectopic pregnancy (23 cases), torsion or hemorrhage from ovarian cysts (13 cases), pyosalpinx or tubo-ovarian abscess (9 cases), torsion of pedunculated uterine leiomyoma (7 cases), intraperitoneal bleeding from hemorrhagic corpus luteum (6 cases), hematocolpos and hematometra from imperforate hymen (3 cases).

[Computerized tomography of the orbit in Graves' ophthalmopathy. New observations].

In order to evaluate Graves' ophthalmopathy new CT parameters have been introduced such as: the diameters of the five extraocular muscles, the value of their addition, the grade of apical crowding, the enlargement of optic nerve sheaths and of the superior ophthalmic vein, and the anterior displacement of the lacrimal gland. On this subject we report our further experience after reviewing 68 cases in which the new ocular parameters were correlated with altered ocular motility and optic neuropathy. The results confirmed our previous study, dealing with several groups of patients, which at the moment seem to be 2, instead of 3 groups: a) patients with increase in both muscular and fatty tissue (54/68 cases); b) patients with main or exclusive increase in fatty tissue (14/68 cases).

[The echographic picture of the breast following quadrantectomy and radiation therapy].

Our experience moved from the clinical relevance of an eventual positive role of US in the follow-up of breast cancers treated with conservative therapy. This trial was suggested by the more and more frequent use of conservative therapy an by the diagnostic difficulties offered by the breasts treated with surgery and radiation therapy. Aim of the study is to analyze the diagnostic value of US in the identification of local relapse in a group of 60 patients with breast carcinoma (stages I and II) treated with conservative therapy.

[Mammographic control after quadrantectomy and radiation therapy].

The efficacy of combined surgery and radiation therapy in the treatment of breast cancer has increased the use of mammography in the follow-up to detect early recurrences. The authors report their experience in the follow-up of 43 breast cancers after treatment with local excision, axillary dissection, and irradiation. Mammography was performed at 6.
