RESUMO

Breast hamartoma is a relatively rare pathology, composed of various amount of mammary glandular, fatty and fibrous tissue. Here, we report MR findings of two cases of hamartomas; one of them was incidentally found in her left breast during preoperative MRI in a woman with right breast cancer, and the other was presented as a large palpable mass. Both of them were confirmed by surgical excision. Breast hamartoma shows a well-defined mass with mixed signal intensity on T2-weighted image MRI and a little or focal enhancement on contrast-enhanced MRI.

RESUMO

PURPOSE: Aging and atherosclerotic changes enhance the stiffness of the arterial wall, and the pulse wave travels faster in stiffer vessel. Measurement of the brachial ankle pulse wave velocity (baPWV) is a non-invasive method for evaluating the stiffness of the vessel wall. We investigated the relation between the baPWV and risk factors for atherosclerosis. METHOD: We studied 180 subjects (38 male and 142 female; mean age 46 years, range 24 to 76 years). The instrument used for evaluating the baPWV was a Vasoguard (VIASYS Healthcare, Dublin, Ohio, USA), and measurements were performed in the right arm and in both ankles. Data were analyzed using Pearson correlation, t-test, and multiple regression analysis. Multiple regression analysis was performed for age, sex, smoking, hypertension, height, weight, body mass index (BMI), total cholesterol, LDL, HDL, TG, and HbA1c. RESULT: Right and left baPWVs were significantly increased (P<0.05) in subjects with the following risks: older age, high body weight, high BMI, high total cholesterol, high LDL, high TG, high HbA1c, and low HDL. Right and left baPWVs were also significantly increased (P<0.05) in male subjects with a history of smoking and hypertension. Multiple regression analysis showed that age, sex, and LDL were independent determinants of the right and left baPWVs. CONCLUSION: This study provides evidence that increased age, male gender, and high serum LDL levels are risk factors that contribute to arterial stiffness. Measurement of the baPWV may be a useful method for evaluating vascular status.
