Magnetic Resonance Imaging and Clinical Features in Acute and Subacute Myelopathies.

Differential diagnosis of acute and subacute transverse myelopathy includes inflammatory, infectious, vascular, metabolic and paraneoplastic etiologies. Information on the diagnostic approach to transverse myelopathy with regard to daily clinical practice is provided. The differentiation between five lesion patterns on magnetic resonance imaging (MRI) in myelitis may be helpful: (1) longitudinal extensive transverse myelitis, (2) short segment ovoid or peripherally located, (3) "polio-like", (4) granulomatous and (5) segmental with rash.

Spinal cord ischemia: aetiology, clinical syndromes and imaging features.

Introduction: The purpose of this study was to analyse MR imaging features and lesion patterns as defined by compromised vascular territories, correlating them to different clinical syndromes and aetiological aspects.

Methods: In a 19.8-year period, clinical records and magnetic resonance imaging (MRI) features of 55 consecutive patients suffering from spinal cord ischemia were evaluated.

Toxic leukoencephalopathy after heroin abuse without heroin vapor inhalation: MR imaging and clinical features in three patients.

Background And Purpose: Toxic leukoencephalopathy has been associated with illicit heroin vapor inhalation. Despite the nonspecific and variable clinical presentation of these patients, they show typical radiologic findings. Previous studies evaluated typical radiologic findings with symmetric infratentorial hyperintense signal changes and similar alteration in the posterior limb of the internal capsule, the splenium of corpus callosum, the medial lemniscus and the lateral brainstem.

Assessment of paramedian thalamic infarcts: MR imaging, clinical features and prognosis.

Considering the highly variable vascular supply of the thalamic nuclei, MRI and clinical syndromes can be heterogeneous in ischemic diseases. We attempt to determine MRI pattern and to analyse neurological features and prognosis of paramedian infarcts. In a prospective case series within 5 years from 1999 to 2003, MRI, MRA and clinical symptoms of 38 consecutive patients were analysed.

Wernicke encephalopathy: MR findings and clinical presentation.

Wernicke encephalopathy (WE) is a severe neurological disorder caused by vitamin B1 deficiency. The aim of the study was to analyse MRI findings typical for this disease and to evaluate the significance of their correlations with clinical symptoms. Magnetic resonance images and clinical features of 12 patients with WE were analysed.

Spinal cord infarction: MR imaging and clinical features in 16 cases.

Spinal cord infarctions are rare and due to heterogeneous etiologies. The aim of the study was to analyze the MR imaging findings and evaluate their correlations with clinical symptoms in ischemic spinal cord lesions. MR images and clinical features of 16 patients (11 male, 5 female) with typical sudden onset of neurological deficits caused by spinal cord ischemia were evaluated.
