Central positional nystagmus arises due to disruption of brainstem or cerebellar vestibular networks. Most patients with central had lesions focal diffusion pontine lesion. From a clinical perspective, the presence is thus highly predictive in posterior fossa, including apparatus, nuclei, and midline structures within vermis. We experienced infarction dentate nucleus.

Liver imaging in patients with a history of known or suspected malignancy is important because the liver is a common site of metastatic spread, especially tumours from the colon, lung, pancreas and stomach, and in patients with chronic liver disease who are at risk for developing hepatocellular carcinoma. Since benign liver lesions are common, liverimaging strategies should incorporate liver le...

Radiol Bras. 2014 Set/Out;47(5):VII–VIII In the last decade, magnetic resonance imaging (MRI) with the use of intravenous extracellular contrast agents (for example, Gd-DTPA and Gd-DOTA) has been recognized as the noninvasive diagnostic tool of choice in the evaluation of focal liver lesions thanks to the fact that it does not require ionizing radiation in association with its high spatial reso...

The goal is assessing the diffusion magnetic resonance imaging (dMRI) method efficiency in characterizing focal hepatic lesions (FHLs). About 28-FHL patients were studied in Radiology and Clinical Imaging Department of our University Hospital using 1.5 Tesla MRI system between January 2010 and June 2011. Patients underwent hepatic MRI consisting of dynamic T1- and T2-weighted imaging. The dMRI ...

A 56-year-old female patient with an unremarkable history was admitted to hospital in August 2009 for constitutional symptoms with a weight loss of 8 kg over the previous year, early satiety, and epigastric pain treated with omeprazole and domperidone on an outpatient basis. Physical examination revealed hepatomegaly extending 3 cm below the right costal margin and palpation of the spleen apex ...

An Intrahepatic mass was found in a 65 year old Chinese female who came to our center for a routine ultrasound exam. MRI showed a lesion in her left lobe of the liver. Surgical records revealed a history of splenomegaly in conjunction with cirrhosis due to hepatic schistosomiasis, for which she underwent surgery (splenectomy) at age 20. On abdominal computed tomography scan, a 4.2 × 5.6 cm size...

OBJECTIVE To clarify the validity of the evaluation of the hemodynamics of hepatic lesions < or =20 mm in diameter using contrast-enhanced ultrasonography (CE-US) with Sonazoid. METHODS Sixty-two hepatic lesions in 55 patients with chronic hepatitis or cirrhosis due to hepatitis C virus were studied. We evaluated by quantitative analysis the time intensity curve (TIC) on hepatic lesion and pa...

Isolated hepatic tuberculoma is localized hepatic tuberculosis (TB) without bile duct involvement, which presents as solitary or multiple nodular mass lesion of liver mimicking a neoplastic lesion in radiological evaluation. Clinical presentation and biochemical tests for liver functions show non-specific abnormality, which is not helpful for diagnosis. As the treatment, modality of isolated he...
