Hematological malignancies rarely affect the breast, and the majority of those that do are lymphomas. In this review, we describe the clinical aspects and multimodal imaging findings of breast lymphoma. We also illustrate the key clinical and radiological findings that allow it to be distinguished from various other malignant and benign diseases of the(More)
RATIONALE AND OBJECTIVES HER-2/neu is a valuable prognostic and therapeutic marker in primary breast carcinoma. The objective of this study was to determine the mammographic and patient characteristics (age) that correlate with HER-2/neu overexpression in primary breast carcinoma. MATERIALS AND METHODS HER-2/neu characteristics and preoperative mammograms(More)
PURPOSE To review the computed tomographic (CT) features of segmental misty mesentery (SMM) in 29 patients and assess the primary causes of this CT finding. MATERIALS AND METHODS The authors analyzed the medical records and CT features of SMM in 29 patients. CT images were evaluated for the site, thickness, and vascular changes of the involved mesentery;(More)
OBJECTIVE This study evaluated the anatomic significance and sites of aortic bifurcation, right renal artery, and conus medullaris when locating lumbar vertebral segments on MRI. SUBJECTS AND METHODS. The study group was composed of 210 patients who underwent MRI of the lumbosacral spine. The position of aortic bifurcation was evaluated using MRI. Midline(More)
Most well-circumscribed breast masses are benign lesions such as cysts, fibroadenomas, and intramammary lymph nodes. Nevertheless, 10%-20% of breast malignancies are well-circumscribed masses, and these malignancies include papillary, mucinous, medullary, and metaplastic carcinomas, as well as malignant phyllodes tumors. Therefore, it is important to(More)
Plasma cell leukemia is a rare malignant plasma cell disorder characterized by proliferation of plasma cells in blood and the bone marrow, the outcome of which is poor with conventional therapy. More effective treatment strategies are therefore needed for this disorder. Here, we report a case of secondary plasma cell leukemia from Immunoglobulin D multiple(More)
Neurofibromatosis type 1 is characterized by cutaneous neurofibromas and pigmented lesions of the skin called café au lait spots. Although neurofibromatosis type 1 represents a major risk factor for the development of malignancy, especially of nervous system tumors, malignant lymphoma rarely occurs in a patients with neurofibromatosis type 1. Recently, a(More)
BACKGROUND AND PURPOSE Ultrasound has been used successfully to differentiate benign and malignant breast lesions. The aim of this study was to investigate the correlation between ultrasound and prognostic indicators in breast cancer such as histological type, tumor grade, and biological markers. MATERIALS AND METHODS Ultrasound findings (shape, margin,(More)
OBJECTIVE To compare image quality and diagnostic accuracy of 2D with 3D ultrasonography in solid breast masses. METHODS AND MATERIAL To rate image quality, two radiologists compared lesion contrast and characterization of 507 solid breast masses in 2D and 3D ultrasonography and then graded the 3D imaging in 3-point scale. To characterize the masses, the(More)
RATIONALE AND OBJECTIVES Diagnostic mammography is performed on women with clinical symptoms that suggest breast cancer or women for whom further mammographic evaluation has been requested because of an abnormal screening mammography. We assessed whether the use of full-field digital mammography would improve the positive predictive value (PPV) for the(More)
