Tumefactive Multiple Sclerosis: The Lethal Chameleon.

Unlabelled: Tumefactive multiple sclerosis (TMS) is a rare variant of multiple sclerosis that presents with a large demyelinating lesion in the central nervous system, accompanied by peripheral ring-like enhancement, perilesional oedema and mass effect. We report a case of a 59-year-old woman who was admitted to the hospital with a four-day history of somnolence, muscle weakness in her left extremities and ultimately, loss of consciousness. Over the following 48 hours, the patient's condition worsened with progressive consciousness impairment.

Unusual Presentation of Prostate Cancer: A Case Report.

Prostate cancer is the second-most common malignancy in males. Despite more frequently metastasizing to the bone, regional lymph nodes, and liver, the brain can also be affected. These metastases can simulate meningiomas, making the diagnosis more difficult.

Spontaneous splenoazygos shunt in a patient with portal hypertension: an exceedingly rare occurrence.

We present a case of a spontaneous splenoazygos shunt in a patient with liver cirrhosis and portal hypertension, detected by abdominal magnetic resonance imaging. Multiplanar reconstruction demonstrated communication of the splenic vein with the azygos vein that was dilated with a winding course along the mediastinum. This pathway for decompression of the portal vein is an exceedingly rare occurrence.

Infectious and Inflammatory Diseases of the Urinary Tract: Role of MR Imaging.

Urinary tract infection (UTI) is among the most common of bacterial infections. Imaging studies are only required in cases of complicated UTIs. Ultrasound remains the first-line imaging method; however, CT is the gold standard for evaluation of UTIs.

Magnetic resonance imaging ancillary features used in Liver Imaging Reporting and Data System: An illustrative review.

Hepatocellular carcinoma (HCC) usually develops in the setting of chronic liver disease. In the adequate clinical context, both multiphasic contrast-enhanced CT and magnetic resonance imaging are non-invasive modalities that allow accurate diagnosis and staging of HCC, although the latter demonstrates greater sensitivity and specificity. Imaging criteria for HCC diagnosis rely on hemodynamic features such as hyperenhancement in the arterial phase and washout in the portal or equilibrium phase.

Transition from screen-film to computed radiography in a paediatric hospital: the missing link towards optimisation.

In paediatrics, the risks associated with ionising radiation should be a major concern, due to children's higher susceptibility to radiation effects. Measure entrance skin dose (ESD) in chest and pelvis X-ray projections and compare the results with the 'European guidelines on quality criteria for diagnostic radiographer images in paediatrics' in order to optimise radiological practice. ESD values were obtained using an ionisation chamber Diamentor M4 KDK (PTW) in 429 children, who underwent chest X-ray or pelvis X-ray in a Computed Radiography system.
