Liver transplantation in a patient with rapid onset parkinsonism-dementia complex induced by manganism secondary to liver failure.

Bilateral and symmetric globus-pallidus hyperintensities are observed on T1-weighted MRI in most of the patients with chronic liver failure, due to manganese accumulation. We report a 53-year-old man, with rapid onset parkinsonism-dementia complex associated with accumulation of manganese in the brain, secondary to liver failure. A brain MRI was performed and a high signal on T1-weighted images was seen on globus-pallidus, as well as on T2-weighted images on the hemispheric white-matter.

The role of the irritative zone and of the number and distribution of calcifications in the severity of epilepsy associated with intracranial calcifications.

Objective: To determine the influence of the location of the irritative zone, and the number and the distribution of the intracranial calcifications in the severity of epilepsy associated with intracranial calcifications.

Method: We studied 47 patients with epilepsy and intracranial calcifications, 24 with normal (Group A) and 23 with abnormal interictal EEGs (Group B), a control group (n=21) with abnormal interictal EEGs and normal CT-scans (Group C). Clinical, electroencephalographic and neuroradiological features were compared among groups.

Central nervous system paracoccidioidomycosis: imaging findings in 17 cases.

Purpose: To quantify the imaging findings of 17 patients with central nervous system (CNS) paracoccidioidomycosis.

Method: Retrospective analysis of the clinical data, films, and laboratory findings of 17 patients with CNS paracoccidioidomycosis. The clinical data were obtained by medical records review.

[Ossification of the posterior longitudinal ligament in the cervical spine: case report].

Ossification of the posterior longitudinal ligament (OPLL) is an uncommon cause of compressive myelopathy in the Caucasian population. A case of spastic paraparesis in a Caucasian man whose radiological investigation showed OPLL is presented. The radiographs of the cervical spine showed a strip of bony density posterior to the vertebral bodies, extending from C2 to T1.

[Visual and volumetric analysis with magnetic resonance of hippocampus formations in a group of patients with clinical diagnosis of temporal lobe epilepsy].

The purpose of this study is to test the sensitivity of the volumetric analysis compared to the visual analysis of the hippocampal formations of a group of 153 patients with clinical diagnosis of temporal lobe epilepsy and candidates to temporal lobectomy, evaluated by magnetic resonance (MR), using a 0.5 Tesla machine and inversion-recovery T1-weighted images and 5 mm coronal slices. There was agreement between the prospective visual analysis and another retrospective visual analysis carried out by two independent observers (C = 0.
