Anti-Hu-associated paraneoplastic limbic encephalitis presenting as rapidly progressive non-convulsive status epilepticus.

We report a 68-year-old woman who developed refractory non-convulsive generalized status epilepticus secondary to anti-Hu antibodies, detected by immunofluorescence and confirmed by Western immunoblotting. The patient presented with rapidly evolving impairment in consciousness and electroencephalographic evidence of lateralized pseudoperiodic sharp-wave discharges. Ataxia and sensory neuropathy developed within the first two weeks.

Fulminant leukemic polyradiculoneuropathy in a case of B-cell prolymphocytic leukemia. A clinicopathologic report.

A 52 year old man with a 10-month history of B-cell prolymphocytic leukemia (PLL) died of an apparent acute fulminant polyradiculoneuropathy, a condition generally attributed to paraneoplastic complication. The pathologic examination disclosed diffuse leukemic infiltrations of the peripheral nervous system. It is suggested that this particularly aggressive form of B-cell chronic prolymphocytic leukemia presented a constellation of features that promoted the invasion of the peripheral nervous system by way of the bloodstream and may explain the unusual clinical presentation.

Magnetic resonance imaging of periventricular hyperintensity in a Veterans Administration hospital population.

Using a beta-permanent magnet (Fonar 3000), we evaluated magnetic resonance imaging of periventricular hyperintensity (PVH) patterns in 60 patients (59 white, 58 men) from the Veterans Administration Hospital, North Chicago, Ill. Eighty percent of the patients had evidence of PVH, which increased significantly in patients older than age 50 years. In addition to age, history of atherosclerotic cardiovascular disease and extracranial malignancy showed a significant association with PVH.

Early diagnosis of spinal-epidural metastasis by magnetic resonance imaging.

Sixteen patients with various types of cancer who developed pain along the axial spine were prospectively studied by magnetic resonance imaging (MRI). The studies were performed with a Fonar Beta-3000 (Fonar Co., Melville, NY) permanent magnet operating at 0.

Carbon monoxide toxicity: MR imaging in the brain.

Two cases of magnetic resonance (MR) imaging of intracranial abnormalities resulting from carbon monoxide toxicity are presented. Both cases demonstrate lesions in the globus pallidi of high MR signal intensity that correspond to previously reported abnormalities; the second case illustrates bilateral cortical high signal intensity lesions. The superiority of MR imaging in comparison with computed tomography is demonstrated in one case.
