A rarely described Kimura's disease of the breast.

Kimura's disease is a rare chronic inflammatory disease of unknown aetiology. The majority of cases are reported in middle-aged Asian males and rarely seen in other ethnicities. Patients classically present with chronic single or multiple painless subcutaneous masses, lymphadenopathies, hypereosinophilia and elevated serum immunoglobulin E.

Task-Based Model Observer Assessment of A Partial Model-Based Iterative Reconstruction Algorithm in Thoracic Oncologic Multidetector CT.

To investigate the impact of a partial model-based iterative reconstruction (ASiR-V) on image quality in thoracic oncologic multidetector computed tomography (MDCT), using human and mathematical model observers. Twenty cancer patients examined with regular-dose thoracic-abdominal-pelvic MDCT were retrospectively included. Thoracic images reconstructed using a sharp kernel and filtered back-projection (reference) or ASiR-V (0-100%, 20% increments; follow-up) were analysed by three thoracic radiologists.

Pulmonary vein occlusion and lung infarction complicating non-treated moderate single pulmonary vein stenosis after radiofrequency ablation of atrial fibrillation.

Pulmonary vein (PV) radiofrequency ablation (RFA) is an effective, curative technique for selected group of patients with atrial fibrillation (AF) refractory to antiarrhythmic drugs. However, pulmonary vein stenosis (PVS) is a potential complication which may present clinically as non-specific respiratory symptoms that often under-recognized or misdiagnosed leading to progression of low-grade stenosis to complete occlusion if not treated with timely intervention.

Current artefacts in cardiac and chest magnetic resonance imaging: tips and tricks.

Currently MRI is extensively used for the evaluation of cardiovascular and thoracic disorders because of the well-established advantages that include use of non-ionizing radiation, good contrast and high spatial resolution. Despite the advantages of this technique, numerous categories of artefacts are frequently encountered. They may be related to the scanner hardware or software functionalities, environmental factors or the human body itself.

Focal pleural thickening mimicking pleural plaques on chest computed tomography: tips and tricks.

Diagnosis of pleural plaques (PPs) is commonly straightforward, especially when a typical appearance is observed in a context of previous asbestos exposure. Nevertheless, numerous causes of focal pleural thickening may be seen in routine practice. They may be related to normal structures, functional pleural thickening, previous tuberculosis, pleural metastasis, silicosis or other rarer conditions.
