Clinical imaging
-
A 53-year-old woman presented to the emergency department with a 2-week history of dyspnoea and chest pain. Computed tomography pulmonary angiography was performed to exclude acute pulmonary embolism (PE). ⋯ Surgical resection was then performed confirming a giant right atrial myxoma. We describe the typical clinical, radiologic, and pathologic features of right atrial myxoma.

Bilateral infarctions of the thalamus account for only a small fraction of ischemic strokes and carry a poor prognosis. These infarcts rarely have a venous etiology. ⋯ Difficulties in considering the diagnosis and its radiological appearances are discussed. A simple imaging pathway including computed tomographic angiography and magnetic resonance imaging including a susceptibility-weighted sequence is presented in order to facilitate determination of the exact etiology in order to optimize therapy accordingly.

Case Reports
Renal vein thrombosis and asymptomatic massive pulmonary embolism: case presentation and diagnostic recommendations.
Isolated renal vein thrombosis is a rare radiographic finding. We present a patient whose complaint of flank pain led to the diagnosis of a renal vein thrombosis and uncovered massive pulmonary emboli. In this case, computed tomography (CT) of the chest was helpful in diagnosing the pulmonary emboli that were asymptomatic and allowed clinical management to be properly directed.

To investigate the feasibility of determining local inflammatory activity of Crohn's disease by measurement of bowel wall perfusion kinetics using contrast-enhanced magnetic resonance imaging (MRI). ⋯ Determination of the perfusion kinetics of the bowel wall by MRI enables quantitative evaluation of local inflammatory activity in patients with Crohn's disease.

Case Reports
Coronary ostial involvement in acute aortic dissection: detection with 64-slice cardiac CT.
A 41-year-old man collapsed after lifting weights at a gym. Following admission to the emergency department, a 64-slice cardiac computed tomography (CT) revealed a Stanford Type A aortic dissection arising from a previous coarctation repair. Multiphasic reconstructions demonstrated an unstable, highly mobile aortic dissection flap that extended proximally to involve the right coronary artery ostium. Our case is an example of the application of electrocardiogram-gated cardiac CT in directly visualizing involvement of the coronary ostia in acute aortic dissection, which may influence surgical management.
