PURPOSE Stereotactic pallidotomy, which has evolved as a result of technological advances in high-resolution MR imaging and microelectrode electrophysiological recording, is becoming a major form of treatment for patients with Parkinson disease in whom medical therapy has failed. We describe the location and appearance of the pallidotomy lesion on high-resolution MR images. METHODS MR images ...

BACKGROUND AND PURPOSE Animal models have clearly shown a critical role for extravascular blood in the initiation of the vasogenic edema associated with intracerebral hemorrhage (ICH). Nevertheless, the relevance of these observations to the human disease process has not been evaluated. With a prospectively collected cohort of nine patients, we report the relation between intraparenchymal blood...

MR imaging has found abnormalities compatible with low-grade edema in the brain of patients with cirrhosis that have been related to hepatic encephalopathy. We present 3 patients with hepatic encephalopathy who exhibit supratentorial focal or diffuse white matter lesions compatible with small-vessel brain disease. The volume and number of white matter lesions reduced with the improvement of hep...

Purpose To investigate the associations between soluble CD14 (sCD14), a cytokine released by microglia and macrophages, and hyperreflective foci (HF) and various characteristics of spectral-domain optical coherence tomography (SD-OCT) in diabetic macular edema (DME). Methods Sixty-nine eyes from 51 patients with DME and 28 eyes from 28 control subjects were studied. sCD14 levels in the aqueou...

We describe a case of neonatal stroke in the territory of the left middle cerebral artery. Although the ischemic lesion appeared rather homogeneously hyperintense on T2-weighted MR images, corresponding diffusionweighted images clearly delineated two separate zones of different cellular swelling and, thus, different prognoses. Lasting cytotoxic edema heralded infarction. We believe that the dif...

Background T2-weighted cardiac magnetic resonance (CMR) can visualize myocardial edema in salvaged myocardium which appears non-infarcted by late gadolinium enhancement (LGE) CMR. However, the mechanisms governing why LGE does not visualize edema in noninfarcted myocardium remain unclear. The objective of the study was to evaluate the extracellular volume fraction (ECV) of edematous salvaged my...

fruits of olea europaea l. have been used for centuries in folk medicine to treat many inflammatory diseases. in order to evaluate the anti-nociceptive activities of the methanolic and aqueous extracts of defatted fruits of o. europaea, formalin test was used and for evaluation of anti-inflammatory effects of the extract, the volume of paw edema was measured. the results revealed that both extr...
