rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...

Tuberous sclerosis (TS) is an autosomal dominant neurocutaneous syndrome characterized by multiorgan hamartomas, epilepsy and mental retardation. Prenatal genetic testing for a mutation is laborious, time consuming and not widely available because of the genetic heterogeneity, polymorphism and a high rate of denovo mutations(1,2). We hereby highlight the utility of prenatal magnetic resonance i...

IntrOductIOn With advances seen in medical imaging (for example, functional magnetic resonance imaging), and development of new drugs and breakthroughs in molecular medicine (for example, neuroprotective agents for Parkinson’s disease [PD]), many clinicians may become caught up in the idea that PD is merely a movement disorder with motor symptoms only. However, research has shown that patients ...

Brain activity during rest is spatially coherent over functional connectivity networks called resting-state networks. In resting-state functional magnetic resonance imaging, independent component analysis yields spatially distributed network representations reflecting distinct mental processes, such as intrinsic (default) or extrinsic (executive) attention, and sensory inhibition or excitation....

Reversible focal lesions on the splenium of the corpus callosum (SCC) have been reported in patients with mild encephalitis/encephalopathy caused by various infectious agents, such as influenza, mumps, adenovirus, Varicella zoster, Escherichia coli, Legionella pneumophila, and Staphylococcus aureus. We report a case of a reversible SCC lesion causing reversible encephalopathy in nonfulminant he...

Imaging neuroscience links human behavior to aspects of brain biology in everincreasing datasets. Existing neuroimaging methods typically perform either discovery of unknown neural structure or testing of neural structure associated with mental tasks. However, testing hypotheses on the neural correlates underlying larger sets of mental tasks necessitates adequate representations for the observa...
