BACKGROUND Intravascular lymphoma (IVL) is a rare non-Hodgkin's lymphoma with relative predilection for the central nervous system. In the absence of extraneural manifestations, the disease is not recognised until autopsy in the majority of cases underlining the need for new clinical markers. METHODS This is a retrospective series of five patients with IVL seen at a single institution over th...

A total of two postpartum women with no noteworthy medical history presented with persistent headache. Brain magnetic resonance imaging (MRI) of both revealed extensive cerebral venous thrombosis, concurrently with abnormal signals of the splenium of the corpus callosum (SCC): The splenium appeared hyperintense on T2-weighted sequences, fluid-attenuated inversion recovery (FLAIR), and diffusion...

A 67-year-old man with a history of prostatic hypertrophy developed behavioral anomalies and a fever. At admission, diffusion-weighted brain magnetic resonance imaging (MRI) indicated a high-intensity signal lesion on both sides of the cerebral hemisphere. Immediately after hospitalization, he developed paralysis of the left side of the body. Diffusion-weighted MRI indicated hemorrhagic changes...

OBJECTIVE The purpose of this research work was to evaluate complex cystic breast lesions by advanced MRI techniques and correlating imaging with histologic findings. METHODS AND MATERIALS In a cross-sectional design from September 2013 to August 2015, 50 patients having sonographically detected complex cystic lesions of the breast were included in the study. Morphological characteristics wer...

BACKGROUND AND PURPOSE Perfusion imaging has the potential to select patients most likely to respond to thrombolysis. We tested the correspondence of computed tomography perfusion (CTP)-derived mismatch with contemporaneous perfusion-diffusion magnetic resonance imaging (MRI). METHODS Acute ischemic stroke patients 3 to 6 hours after onset had CTP and perfusion-diffusion MRI within 1 hour, be...

BACKGROUND Reduced apparent diffusion coefficients (ADCs) correlate with cerebral ischemia. The combination of ADC with techniques to measure cerebral perfusion may help to assess the effect of treatment. CASE DESCRIPTION The authors describe a patient who experienced an acute stroke with hemianopia, consequently treated with intravenous recombinant tissue plasminogen activator. Positron emis...

Worldwide, non-contrast computed tomography (NCCT) has been the imaging modality of choice in acute stroke, primarily due to its accessibility and short acquisition time. However, magnetic resonance imaging (MRI), specifically diffusion-weighted imaging (DWI), is much more sensitive to hyperacute ischemic changes. Multimodal MRI studies provide significantly more pathophysiological and prognost...
