Heroin-associated spongiform leukoencephalopathy is a rare, and sometimes fatal, condition usually caused by vapor inhalation of heroin. The authors report a 41-year-old man who was diagnosed with delayed spongiform leukoencephalopathy three weeks after injecting heroin intravenously. He had been admitted to another hospital due to acute heroin overdose, which had occurred four hours after intr...

OBJECTIVE To report the clinical and radiologic features in a patient with myelofibrosis who developed atypical progressive multifocal leukoencephalopathy. DESIGN Case report. SETTING Tertiary referral center. Patient A 72-year-old man with myelofibrosis and mild leukopenia experienced progressive limb weakness and dysarthria. RESULTS Imaging revealed almost complete sparing of the white ...

Toluene‐induced leukoencephalopathy is a frequently seen medical condition worldwide; however the lack of specific clinical manifestations and laboratory tests makes it difficult to diagnose. Neuroimaging and medical history are often crucial to diagnosis of this disorder. In this report, a case is presented of a patient suffering from toluene‐induced leukoencephalopathy with deteriorating cogn...

PubMed Citation Leukoencephalopathy is a structural alteration of cerebral white matter in which myelin suffers the most damage. Toxic leukoencephalopathy may be caused by exposure to a wide variety of agents, including cranial irradiation, therapeutic agents, drugs of abuse, and environmental toxins.1 Toxic leukoencephalopathy particularly involves white-matter tracts devoted to higher cerebra...

BACKGROUND AND PURPOSE Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy is caused by mutations in the NOTCH3 gene and is clinically characterized by recurrent stroke and cognitive decline. Previous studies have shown an association between white matter hyperintensities on brain MRI and cognitive dysfunction in cerebral autosomal dominant arteriopathy wi...

A 40-year-old male with recent-onset idiopathic thrombotic thrombocytopenic purpura (TTP) developed focal transient neurological findings lasting for several hours, remitting, then recurring in a different pattern. Brain magnetic resonance imaging (MRI) was consistent with a posterior leukoencephalopathy and electroencephalography demonstrated lateralized slowing during an episode. No acute isc...

Thirty-one (16 women, 15 men; mean age 68 years) of 1,000 consecutive patients with an ischemic stroke investigated systematically with computed tomography (CT), Doppler, electrocardiography (ECG), and biological tests had a diffuse hypodensity of the cerebral hemispheric white matter on CT, a sign indicative of leukoencephalopathy. In 25 of the 31 patients, the acute infarct was deep. Leukoenc...
