Subjects

Abstract

In this monograph, various autoimmune disorders of the nervous system have been discussed. After a brief introduction to the subject in the first chapter, various neural antibodies have been elaborated which help in understanding the disease in the second and then move on to their laboratory diagnosis in the third. In the subsequent five chapters, autoimmune disorders affecting the upper storey have been discussed including the dementias, demyelinating diseases, epilepsies, movement disorders and the cerebellar ataxias. A brief outline about the autoimmune myelopathies in the ninth chapter is followed by a sojourn into the lower storey and how the disorder affects the peripheral nerves, neuromuscular junction, and the muscle in the subsequent three chapters. Finally, different treatment options and the current guidelines are looked upon.

Abstract

The article describes the case of a 5-year-old boy with herpes simplex encephalitis (HSE) who presented with epilepsia partialis continua (EPC) of the tongue. Topics discussed include observations from clinical examination and magnetic resonance imaging of the brain, hyperintense lesions in frontal operculum bilaterally, and early recognition of lingual EPC as a possible presenting feature of HSE.

31. Myelopathy following Cypermethrin Poisoning.

Author

Mugundhan K and Iyer RS

Subjects
Adolescent, Humans, Male, Insecticides poisoning, Pyrethrins poisoning, Spinal Cord Diseases chemically induced
Abstract

Cypermethrin is a synthetic pyrethroid and pyrimethrin analogue. Cypermethrin poisoning produces neurological manifestations due to its primary target on sodium channels.1 Neuropathy following cypermethrin poisoning is common. But myelopathy is rare and not reported so far. We report a 17 year old healthy male who developed myelopathy following cypermethrin ingestion. The possible mechanism for the myelopathy in this patient is discussed., (© Journal of the Association of Physicians of India 2011.)

33. Sudden Simultaneous Cerebellar Infarction in the Territories of the Medial Division of Posterior Inferior Cerebellar Arteries.

Author

Mugundhan K and Iyer RS

Subjects
Female, Humans, Middle Aged, Cerebellum blood supply, Cerebral Arteries, Cerebral Infarction diagnostic imaging
Abstract

Strokes involving posterior inferior cerebellar arteries (PICA) are rare and usually unilateral. They can involve either the lateral division or the medial division of PICA. Sudden simultaneous cerebellar infarctions in the medial PICA territories are extremely rare. We report one such patient who presented with acute bilateral cerebellar infarctions in the medial PICA territories. She was a diabetic and had features of diffuse atherosclerotic vertebrobasilar disease. We discuss the anatomical peculiarities of PICA and its blood supply along with the clinical features differentiating the medial and lateral PICA infarctions. We also list out the possible mechanisms of bilateral medial PICA territory infarction. Though bilateral they generally have a good prognosis considering the very small area of blood supply., (© Journal of the Association of Physicians of India 2011.)

36. 18F-FDG PET/CT findings in voltage-gated potassium channel limbic encephalitis.

Author

Kamaleshwaran KK, Iyer RS, Antony J, Radhakrishnan EK, and Shinto A

Subjects
Adult, Female, Humans, Fluorodeoxyglucose F18, Limbic Encephalitis diagnostic imaging, Limbic Encephalitis metabolism, Multimodal Imaging, Positron-Emission Tomography, Potassium Channels, Voltage-Gated metabolism, Tomography, X-Ray Computed
Abstract

Limbic encephalitis (LE) can be associated with cancer, viral infection, or be idiopathic. One such rare but treatable form is associated with voltage-gated potassium channel (VGKC) antibodies. Typical abnormalities are seen in FDG PET/CT. We report a 39-year-old female patient who presented with 3 months of progressive faciobrachial dystonic seizures and limbic encephalitis. Her serum and cerebrospinal fluid Lgi1 antibody titers were elevated. FDG PET/CT showed basal ganglial hypermetabolism and associated abnormalities. Serial MRI demonstrated atrophic changes predominantly involving the temporal lobes. She is on immunosuppressive therapy and shows clinical improvement with lowering of antibody titers.
