PURPOSE The purpose of this study was twofold: first, to compare two different measures of lesion burden in patients with multiple sclerosis (MS), the magnetization transfer ratio (MTR) histogram and T2 lesion volume; and, second, to investigate the relationship between lesion burden and atrophy in patients with MS. METHODS Thirty patients with MS were examined with MR imaging, including fast...

Neurocysticercosis is one of the common space occupying lesion of brain in Asian countries. Cysticercosis of brain can present in variable forms with or without classic scolex in cyst. As they are so common and treatable cause of new onset seizure, identification of such pathology is crucial in imaging. We are presenting a cystic lesion of brain of middle aged patient with spontaneous onset of ...

SEE MCKAY AND FURL DOI101093/AWW323 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Focal brain injury can sometimes lead to bizarre symptoms, such as the delusion that a family member has been replaced by an imposter (Capgras syndrome). How a single brain lesion could cause such a complex disorder is unclear, leading many to speculate that concurrent delirium, psychiatric disease, dementia, or a ...

The radiological finding of a calcified intracranial lesion commonly represents a slow growing benign mass. Brain metastases originating from colorectal cancers are rare, occurring in approximately 2-3% of patients. Therefore the presence of a calcified brain lesion in a patient with a positive oncological history requires a high index of suspicion for brain metastases. Presented herein is a ca...

A 70-year-old female with a half-month history of schistosomiasis presented to a nonendemic region for treatment. Brain computed tomography (CT) and MRI revealed a lesion in the left occipital lobe; other clinical testing was not remarkable. The diagnosis was an intracranial occupying lesion in the left occipital lobe. After the removal of the brain lesion via cranial surgery, it was noticed th...

We present a patient with alexia secondary to cerebral lesion whose errors in the reading of non-words affect vowels more than consonants. The interest of the case resides in: (1) the documentation of a vowel-consonant dissociation selectively affecting the reading of non-words; and (2) the localization of the alteration in a specific stage of the perilexical reading pathway, that is, the blend...

Our knowledge of the anatomical organization of the human brain in health and disease draws heavily on the study of patients with focal brain lesions. Historically the first method of mapping brain function, it is still potentially the most powerful, establishing the necessity of any putative neural substrate for a given function or deficit. Great inferential power, however, carries a crucial v...

The development of hypothalamic lesions due to goldthioglucose are described. The initial extensive necrotic lesion occurs in close to 100 per cent of animals injected with LD(50). Within 2 weeks the necrotic material has been removed and a narrow scar results. After a lapse of several months, the scar is often difficult to visualize, especially in animals that have not developed obesity. The v...

Visual hemineglect, the failure to explore the half of space, real or imagined, contralateral to a cerebral lesion with respect to body or head, can be seen as an illustration of the brain's Euclidean representation of the left/right axis. Here we present two patients with left-sided neglect, in whom only the left hemispace in front of an imagined and/or real body position was inaccessible, but...
