Peritumoral edema as a biomarker of the aggressiveness of breast cancer: results of a retrospective study on a 3 T scanner.

Purpose: To determine whether there is a correlation between the presence of peritumoral edema detected on T2-weighted sequences and pathological prognostic factors and specific biological subtypes of breast cancer.

Methods: A retrospective study on 120 women with invasive breast cancer, who underwent breast MRI on a 3 T scanner over a period of 12 months, was performed. Peritumoral edema was assessed visually by two breast radiologist in consensus and patients were consequently divided into two groups.

Nipple discharge: The state of the art.

Over 80% of females experience nipple discharge during their life. Differently from lactational (milk production) and physiological (white, green, or yellow), which are usually bilateral and involving multiple ducts, pathologic nipple discharge (PND) is a spontaneous commonly single-duct and unilateral, clear, serous, or bloody secretion. Mostly caused by intraductal papilloma(s) or ductal ectasia, in 5-33% of cases is due to an underlying malignancy.

Extraocular muscle sampled volume in Graves' orbitopathy using 3-T fast spin-echo MRI with iterative decomposition of water and fat sequences.

Background: Current magnetic resonance imaging (MRI) techniques for measuring extraocular muscle (EOM) volume enlargement are not ideally suited for routine follow-up of Graves' ophthalmopathy (GO) because the difficulty of segmenting the muscles at the tendon insertion complicates and lengthens the study protocol.

Purpose: To measure the EOM sampled volume (SV) and assess its correlation with proptosis.

Material And Methods: A total of 37 patients with newly diagnosed GO underwent 3-T MRI scanning with iterative decomposition of water and fat (IDEAL) sequences with and without contrast enhancement.

Microcalcification morphological descriptors and parenchyma fractal dimension hierarchically interact in breast cancer: A diagnostic perspective.

Introduction: Herein, we propose a Systems Biology approach aimed at identifying quantitative morphological parameters useful in discriminating benign from malignant breast microcalcifications at digital mammography.

Materials And Methods: The study includes 31 patients in which microcalcifications had been detected during XR mammography and were further confirmed by stereotactic (XR-guided) biopsies. Patients were classified according to the BIRADS (Breast Imaging-Reporting and Data System), along with their parenchyma fractal dimension and biopsy size.

Circulating leptin and adiponectin levels in patients with primary hyperparathyroidism.

Primary hyperparathyroidism (PHPT) has been associated with high cardiovascular morbidity and mortality; its pathogenesis is not fully understood. Moreover, many metabolic abnormalities are frequently present in patients with PHPT. Several substances (such as leptin and adiponectin) are secreted from adipocytes, which may contribute to regulate energy homeostasis and the development of cardiovascular diseases.

Adrenomedullin immunoreactivity tissue distribution in parathyroids of the patients with primary hyperparathyroidism.

Adrenomedullin (ADM) is a new potent vasorelaxant peptide identified originally in extracts of pheochromocytoma, and is widely distributed within the tissue. Although histopathological studies have demonstrated the presence of ADM-immunoreactivity (ir-ADM) in some human neuroendocrine tumors (such as insulinoma, pituitary adenoma, and gastrointestinal neuroendocrine tumors), data on the presence of ADM in normal and pathological parathyroid gland are not available. Plasma AM concentrations were recently reported to be elevated in patients with PHP (primary hyperparathyroidism).

Bilateral internal jugular vein thrombosis is a rare complication of thyroid cancer. The most common manifestation of this condition is superior vena cava syndrome. We report the sonographic findings in a case of bilateral internal jugular vein thrombosis with mild symptoms.

Preoperative evaluation of primary hyperparathyroidism: role of diagnostic imaging.

This study analyses the diagnostic value of preoperative diagnostic imaging examinations in the identification and location of pathological parathyroid glands. We examined 77 patients with primary hyperparathyroidism using ultrasonography of the neck and Tc99m-MIBI scintigraphy for preoperative assessment purposes. All patients underwent surgical treatment.

Heterotaxia: radiological and surgical observations in a case of polysplenic syndrome.

We describe a case of asymptomatic polysplenic syndrome as suggested by ultrasonography, gastrointestinal series, computed tomography, magnetic resonance imaging scans and arteriography, and confirmed at surgery. Spleen malformation is frequently associated with heterotaxia and other malformations of the thoracic and abdominal organs, but no pathognomonic features can be detected in relation to this condition. In our patient, imaging studies revealed the presence of a polylobulated spleen in an atypical position below the liver, associated with malpositioning of the gastric fundus and gastro-oesophageal junction with interruption of the inferior vena cava, but no congenital heart disease.
