Does white matter lesions mean MS?

Does white matter lesions mean MS?

DIFFERENTIAL RADIOLOGICAL DIAGNOSIS OF WHITE MATTER LESIONS. White matter T2 hyperintensities in the brain are not specific to MS and are seen in a number of other disorders. They can even be seen in otherwise normal individuals, particularly with increasing age.

Will hepatic encephalopathy show up on an MRI?

Magnetic resonance imaging (MRI) findings associated with chronic hepatic encephalopathy are characterized by cerebral atrophy and bilateral symmetric hyperintensities of the globus pallidus on T1-weighted images without corresponding signal intensities in T2-weighted images.

What is a common cause of diffusion abnormality?

The vast majority of restricted-diffusion abnormalities result from acute stroke, and as such, the diagnosis may be problematic when this MRI feature results from other causes. Distinct patterns of restricted diffusion seen with various disease conditions can play an important diagnostic role.

What are periventricular lesions?

A periventricular lesion is defined as a T2-hyperintense cerebral white matter lesion in direct contact with the lateral ventricles, without intervening white matter. Lesions abutting (touching) the ventricles and located in the corpus callosum are included in this definition (Fig.

What causes periventricular lesions?

Major causes of periventricular white matter (PWM) lesions include normal changes from aging (then they are called UBO’s, for “unidentified bright objects), small strokes, and disorders related to multiple sclerosis (MS). PWM are also correlated with vitamin B6 (pyridoxine) deficiency.

Does hepatic encephalopathy show up on CT scan?

CT Scan Is Still a Valuable Tool to Assess Hepatic Encephalopathy Pathophysiology in Both Acute and Chronic Liver Diseases.

What does encephalopathy mean?

Definition. Encephalopathy is a term for any diffuse disease of the brain that alters brain function or structure.

What does periventricular white matter mean?

Periventricular white matter refers to white matter located immediately adjacent to the fluid-filled ventricles of the brain.

Can periventricular lesions (PVL) be found in other neurological diseases?

The presence of periventricular lesions (PVL) on MRI scans is part of the revised McDonald multiple sclerosis (MS) diagnostic criteria. However, PVL can be found in other neurological diseases including stroke and migraine. Migraine is highly prevalent in patients with MS.

What are hypervascular lesions of the liver?

Hypervascular liver lesions are findings that enhance more or similarly to the background hepatic parenchyma in the late arterial phase, on contrast-enhanced CT or MRI. enhancement must match blood pool in each phase, or not a hemangioma (i.e. similar to aorta in arterial, portal vein in portal phase, etc)

Is periventricular lesion a hallmark of multiple sclerosis?

Introduction The presence of periventricular lesion (PVL) has been considered a hallmark of multiple sclerosis (MS) and was included in the 2010 revised McDonald MS criteria of “dissemination in space” [1] based on observation of Swanton et al. [2].

Do benign liver lesions show persistent enhancement on venous and delayed-phase imaging?

Most of these benign lesions demonstrate not only arterial-phase hyperintensity, but also persistent enhancement on venous and delayed imaging, unlike most malignant hepatic mass … Arterially enhancing liver lesions: significance of sustained enhancement on hepatic venous and delayed phase with magnetic resonance imaging
