The Masses

Primary angiosarcoma of the breast is a rare tumor, with approximately 170 cases reported in the literature (1-3, 10, 11, 15). Reports on the imaging characteristics of these tumors have been occasional until a recent review by Liberman et al. (11). Diagnostic imaging of the masses include mammographic and ultrasound examinations (5): the imaging characteristics of the tumor can be nonspecific and sometimes heterogeneous (11). Only recently was one case evaluated with magnetic resonance imaging (11). We present the mammographic and sonographic features of a case of primary angiosarcoma of the breast with an inflammatory appearance.

Purpose The purpose of this study was to evaluate computed tomography and magnetic resonance imaging of benign trichilemmal cysts and proliferating trichilemmal tumours. Methods Nineteen histologically confirmed cutaneous lesions with trichilemmal keratinisation (12 trichilemmal cysts and seven proliferating trichilemmal tumours) were enrolled. Among them, 10 lesions (six trichilemmal cysts and four proliferating trichilemmal tumours) were examined by computed tomography, while 13 lesions (eight trichilemmal cysts and five proliferating trichilemmal tumours) were examined by magnetic resonance imaging. Computed tomography and magnetic resonance imaging characteristics were retrospectively reviewed. RESULTS Sixteen lesions (84%, 10 trichilemmal cysts and six proliferating trichilemmal tumours) occurred on the scalp. Lobulated margins were observed in five lesions (26%, three trichilemmal cysts and two proliferating trichilemmal tumours). With respect to computed tomography attenuation, calcification (>200 Hounsfield units) was observed in seven lesions (70%, five trichilemmal cysts and two proliferating trichilemmal tumours), hyperdense areas (≥80 and ≤200 Hounsfield units) in six (60%, three trichilemmal cysts and three proliferating trichilemmal tumours), and soft tissue density areas (<80 Hounsfield units) in nine (90%, five trichilemmal cysts and four proliferating trichilemmal tumours). On T1-weighted images, intratumoral hyperintensity was only observed in eight trichilemmal cysts but no proliferating trichilemmal tumours (100% vs. 0%, P<0.01). On T2-weighted images, hypointense rim and intratumoral hypointensity was observed in all 13 lesions (100%, eight trichilemmal cysts and five proliferating trichilemmal tumours), and linear or reticular hypointensity was observed in 10 (77%, six trichilemmal cysts and four proliferating trichilemmal tumours). Conclusion Trichilemmal cysts and proliferating trichilemmal tumours predominantly occurred on the scalp with calcification, and usually exhibited linear or reticular T2 hypointensity. Intratumoral T1 hyperintensity may be a useful imaging feature for differentiating trichilemmal cysts from proliferating trichilemmal tumours.

Objective To familiarize the reader with the fundamental concepts of partial parallel imaging (PPI); to review the technical aspects of PPI including calibration scan, coil geometry, and field of view (FOV); and to illustrate artifacts related to parallel imaging and describe solutions to minimize their negative impact. Results PPI has led to a significant advance in body magnetic resonance imaging by reducing the time required to generate an image without loss of spatial resolution. Although PPI can improve image quality, it is not free of artifacts, which can result in significant image degradation. Knowledge of these artifacts and how to minimize their effect is important to optimize the use of parallel imaging for specific body magnetic resonance imaging applications. Conclusions The reader will be introduced to the fundamental principles of PPI. Common imaging characteristics of PPI artifacts will be displayed with an emphasis on those seen with image-based methods, the principles behind their generation presented, and measures to minimize their negative impact will be proposed.

Resonance Imaging

Chest imaging techniques are evolving with recent advances in computed tomography, magnetic resonance imaging, and ultrasonography. While conventional radiography remains an important screening tool because of its low relative cost, ease of acquisition, general availability, and familiarity, physicians must understand all techniques so as to provide patients with the most appropriate diagnostic imaging. Consultation with radiologists, use of online clinical decision support, and adherence to national guidelines such as the American College of Radiology Appropriateness Criteria®, can help clinicians make imaging decisions, especially in light of medical imaging risks that are of concern in the medical community and the general population. Choosing appropriate imaging, including whether or not to image, requires careful consideration. This review contains 6 figures, 3 tables, and 6 references.

AbstractNorovirus is a common cause of acute gastroenteritis outbreaks worldwide. The disease can present with varying degrees of neurologic impairment from benign convulsions to rare cases of severe encephalopathy. We describe a case report of a North American infant who presented with norovirus gastroenteritis, status epilepticus, severe encephalopathy, and abnormal but reversible diffusion restriction changes on magnetic resonance imaging of brain.
