October 2004. A 49-year-old right-handed man developed progressive cognitive difficulties over a 4-month period. There was impairment in recent memory, calculations and language. He also developed fatigue, weight loss, gait imbalance and urinary incontinence. Past history included transfusion-associated Hepatitis C. Neurologic exam showed mild dysarthria, dysnomia, left sided neglect, bilateral Babinski signs, and a prominent grasp reflex. Laboratory testing provided no positive etiologic data. An EEG showed generalized intermittent slowing suggestive of a diffuse encephalopathy and decreased background in the right hemisphere, suggestive of a structural lesion. MRI showed multiple areas of high signal on FLAIR imaging and patchy enhancement. FDG-PET showed multi-focal areas of increased uptake, correlating with the abnormal areas on MRI, on a background of decreased uptake. A 4-vessel cerebral angiogram showed no abnormalities. A brain biopsy showed diffuse infiltrates of large malignant cells that were immunoreactive with antibodies to CD20, diagnostic of diffuse large B cell lymphoma. In summary, the clinical presentation suggested bilateral hemispheric involvement, which was supported by physical examination, EEG, MRI, and PET scans. The differential diagnosis for this presentation is limited to demyelinating disease such as multiple sclerosis, vascular dementia, and infiltrating neoplasm such as glioblastoma multiforme or lymphoma. Diagnosis was made by morphologic and immunohistochemical analysis of brain tissue.

Whipple disease is a relapsing systemic illness caused by Tropheryma whippelii. Central nervous system involvement occurs in 5%-40% of all patients. Hypothalamic manifestations occur in 31% of Whipple encephalopathy, including polydipsia, hyperphagia, change in libido and insomnia. We report a case of a 48-year-old man with severe insomnia, depression, dementia, dysarthria, myoclonic movements of the limbs and ophthalmoplegia. The diagnosis of Whipple encephalopathy was confirmed by PCR analysis of blood and faeces. He received a full dose of antibiotic treatment. Despite clinical improvement, resolution of the lesions detected in MRI scan of the brain and negative results of the PCR in blood, faeces and cerebrospinal fluid six months later, insomnia persisted and finally subsided after the administration of carbamazepine (600 mg/day). Our case supports the finding that carbamazepine might be useful in the treatment of insomnia associated with Whipple encephalopathy.

Hashimoto's encephalopathy is a rare complication of autoimmune thyroiditis not associated with thyroidal function decline. We report a 50-year-old man presenting with lower motor neuron symptoms evolving over 3 years and changes in behavior associated with attentive and cognitive impairment occurring in the last few months. Memory deficits, emotional instability, marked dysarthria, mild symmetric weakness of the lower extremities and fasciculations were the most striking clinical features. EEG was diffusely slow, cranial MRI revealed multiple subcortical white matter lesions, CSF protein was slightly elevated, electromyographic recordings showed acute and chronic denervation and extremely high TPO antibody titers were found in the serum. Hashimoto's encephalopathy and lower motor neuron disease were diagnosed. As repeated high-dose intravenous methylprednisolone administration followed by oral tapering improved both central nervous system and lower motor neuron symptoms, the question was raised whether there was a common autoimmune pathogenesis of both clinically distinct diseases.

Paradichlorobenzene (PDB) is a common household deodorant and pesticide found in room deodorizers, toilet bowl fresheners, and some mothballs. Although human exposure to the compound is generally limited and harmless, PDB in larger doses can produce neurotoxic effects, including a chemical "high" similar to that seen with inhalants such as toluene. Although rare, frank addiction to PDB has been reported, and, in such cases, has been associated with gait ataxia, tremor, dysarthria, limb weakness, and bradyphrenia, in various combinations. In such cases, the adverse neurologic consequences have been presumed to result from a direct toxic effect of this small, organic molecule. We report a case of chronic mothball ingestion where profound encephalopathy with cognitive, pyramidal, extrapyramidal, and cerebellar features appears to have been largely the result of PDB withdrawal, rather than direct toxicity. This case raises important questions about the mechanism of PDB neurotoxicity and possible treatment options for PDB-addicted patients. We propose that in cases with clear clinical deterioration after abstinence, readministration and gradual taper of PDB might be considered a therapeutic option.

Despite popular use of piperacillin, the dire neurotoxicity associated with piperacillin still goes unrecognized, leading to a delay in appropriate management. We report a 57-year-old woman with end-stage renal disease receiving continuous ambulatory peritoneal dialysis (CAPD), who developed slurred speech, tremor, bizarre behavior, progressive mental confusion, and 2 episodes of generalized tonic-clonic seizure (GTCS) after 5 doses of piperacillin/tazobactam (2 g/250 mg) were given for bronchiectasis with secondary infection. The laboratory data revealed normal plasma electrolyte and ammonia levels but leukocytosis. Neurologic examinations showed dysarthria and bilateral Babinski sign. Computed tomography of brain and electroencephalogram were unremarkable. Despite the use of antiepileptic agents, another GTCS episode recurred after the sixth dose of piperacillin/tazobactam. Brain magnetic resonance imaging did not demonstrate acute infarction and organic brain lesions. Initiation of high-flux hemodialysis rapidly reversed the neurologic symptoms within 4 hours. Piperacillin-induced encephalopathy should be considered in any uremic patients with unexplained neurological manifestations. CAPD is inefficient in removing piperacillin, whereas hemodialysis can rapidly terminate the piperacillin-induced encephalopathy.

It is known that rotavirus gastroenteritis can accompany some neurological manifestations, including encephalitis/encephalopathy or seizures. However, the detailed pathogenesis involved has not been fully understood. To date, acute cerebellitis associated rotavirus gastroenteritis has not been previously reported, except for one case. Herein, we describe two cases of acute encephalitis/encephalopathy and concurrent cerebellitis, associated rotavirus gastroenteritis. Following vomiting and diarrhea, case 1 experienced convulsions and consciousness disturbance and case 2, transient loss of consciousness with eye deviation. After these symptoms subsided, cerebellar signs became evident and a brain MRI showed cerebellar involvement in both cases. Both cases showed speech disturbances, such as mutism, slow speech and dysarthria. In this report, we will discuss the possible pathogenesis of rotavirus associated acute encephalitis/encephalopathy and concurrent cerebellitis.

A mitochondrial DNA 3271T>C point mutation was reported to be the second most common mutation (following the mutation 3243A>G) in mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) in Japan. This mutation has rarely been reported in other countries. We present an 11-year-old Taiwanese girl with MELAS, who harbored the 3271T>C mutation and had manifested short stature, epilepsia partialis continua, and recurrent basal ganglia infarctions since age 6 years, and rapid intellectual regression, dysarthria, and unsteady gait since age 10 years. The proportion of 3271T>C mutant genomes in various tissues, including urinary sediments, hair follicles, blood leukocytes, and buccal mucosa cells from the patient and her mother, was analyzed by polymerase chain reaction-restriction fragment length polymorphism analysis and quantitative real-time polymerase chain reaction. The proportion of mutant load in the patient's muscles was near 100%. Except for muscle, the highest mutation load was detected in urinary sediments of the patient by both methods. This is the first report involving mutant load analysis with quantitative real-time polymerase chain reaction in the 3271T>C mutation. The results suggest that urinary sediments may be an alternative tissue of choice which can be obtained noninvasively in the diagnosis of mitochondrial DNA 3271T>C mutations.

Leucoencephalopathy caused by antineoplastic drugs was reviewed. This leucoencephalopathy primarily involved the cerebral white matter, caused by various anti-neoplastic drugs such as carmofur, fluorouracil, cytarabine, cisplatin, tegafur, methotrexate, tacrolimus, and interferon alfa. The interval between the time of drug administration and the onset of leucoencephalopathy varies among the drugs, depending on the kind of the drugs, their daily dosage, duration of the administration, and presence or absence of other combined treatments. This review primarily focused on carmofur-induced leucoencephaloathy, since this drug is developed and widely used in Japan against the carcinomas of the gastrointestinal tract and breast, and has caused leucoencephalopathy at the estimated incidence of 0.026% since 1982. The common symptoms of carmofur leucoencephalopaty were gait disturbance followed by dysarthria and dementia in that order of frequency, leading to coma in the advanced stage of the encephalopathy. EEG is the most sensitive test, but cranial CT and MRI tests are more specific, and MRI T2-weighted imaging is the most useful test, revealing symmetrical bilateral diffuse high intensity areas in the cerebral white matter. Intravenous high dose MTX has a strong tendency to cause leucoencephalopathy when combined with cranial radiation therapy. Reversible posterior leucoencephalopathy proposed by Hinchey et al. in 1996 has also been caused by some antineoplastic drugs. The most important treatment of the leucoencephalopathy caused by antineoplastic drugs is the immediate cessation of the causative drugs, followed by supportive therapy which included treatment to various complications and prevention of the decubitus and contractures of the joints.

We report a 57-year-old woman with uremic encephalopathy who presented with dysarthria, dysphagia, hypophonia, and drowsiness. The patient's radiologic findings were rather unusual in that magnetic resonance imaging (MRI) showed abnormal findings involving the basal ganglia bilaterally and frontal cortex unilaterally. After intensified hemodialysis, her symptoms and follow-up brain MRI showed marked improvement. We postulated that the underlying mechanism of uremic encephalopathy based on diffusion-weighted imaging and apparent diffusion coefficient maps.

A 59-year-old man visited an emergency room due to the sudden onset of severe dysarthria with a drowsy mental status. MRI demonstrated T2 prolongation and restricted diffusion involving the splenium of the corpus callosum and bilateral frontal white matter neurological signs and symptoms were mild, and the recovery was complete within a week. Follow-up MRI performed one month later revealed complete resolution of the lesions. The clinical and radiological courses were consistent with previously reported reversible isolated splenial lesions in mild encephalitis/encephalopathy except for the presence of frontal lesions. This case suggests that such reversible lesions can occur outside the splenium.
