It is still controversial whether intravenous (IV) thrombolysis for acute ischemic stroke increases the risk of aneurysmal bleeding. We sought to find the risk for aneurysmal bleeding after IV thrombolysis in ischemic stroke patients with unruptured cerebral aneurysms. ⋯ The results of this study suggest that IV thrombolysis might not increase the risk of aneurysmal bleeding in acute stroke patients with unruptured aneurysm < 10 mm in diameter. Further studies with a larger sample size are needed to confirm our result.

To determine the interrelationships between MRI-defined lesion and atrophy measures of spinal cord involvement and brain involvement and their relationships to disability in a small cohort of patients with multiple sclerosis (MS). ⋯ In this preliminary study of mildly disabled, treated MS patients, cervical spinal cord atrophy most strongly correlates with physical disability in MS when accounting for a wide range of other CNS measures of lesions and atrophy, including thoracic or whole spinal cord volume, and cerebral gray, white or whole brain volume. The weak relationship between spinal cord and brain lesions and atrophy may suggest that they progress rather independently in patients with MS.

This report describes a rare complication in a woman who underwent thoracic spinal surgery. One month postoperatively, her rehabilitation was interrupted by the development of a severe headache, nausea, vomiting, and a right-side occulomotor nerve palsy. ⋯ The CSF was seen to track into the right pleural space via a dural-pleural fistula. Surgical repair of the fistula led to a definitive resolution in symptoms, thus highlighting the importance of early recognition of this highly unusual complication.

Wernicke's encephalopathy is a metabolic disorder caused by deficiency of thiamine (vitamin B1) seen in alcoholics and even in nonalcoholic patients, classically presenting with a triad of ataxia, ophthalmoplegia, and altered mental status. Typical findings in magnetic resonance imaging are represented by symmetric signal alterations in medial thalami, mamillary bodies, tectal plate, and periaqueductal area and atypical findings involve lesions in cerebellum, midline vermis, red nuclei, dentate, caudate, cranial nerve nuclei, splenium and cerebral cortex. We report here a case of nonalcoholic starvation induced atypical WE showing symmetrical lesions in substantia nigra in addition to the classical neuroradiological findings.
