    Diffusion restriction in thrombosed superior ophthalmic veins: two cases of diverse etiology and literature review.
    (Journal of radiology case reports, 2011)
    Thrombosis of superior ophthalmic veins (SOV) is a well known entity occurring secondary to varied etiologies. We describe diffusion restriction in thrombosed SOV in two cases of different etiologies- bilateral involvement in a patient with septic cavernous sinus thrombosis (CST) and another where embolisation of an indirect carotico-cavernous fistula (CCF) resulted in complete SOV thrombosis accompanied by clinical worsening. Our cases add to the limited literature on diffusion findings in SOV thrombosis.

    Electrodiagnostic and clinical aspects of Guillain-Barre syndrome: an analysis of 142 cases.
    (Journal of clinical neuromuscular disease, 2008)
    BACKGROUND: The incidence of Guillain-Barre syndrome (GBS) and its subtypes varies throughout the world.OBJECTIVE AND METHODS: We present a retrospective analysis of 142 GBS cases, treated at our center, aimed at classifying GBS electrophysiologically, to study the sequential electrophysiological changes in cases with acute inflammatory demyelinating polyradiculoneuropathy (AIDP), and to look for any clinical and cerebrospinal fluid parameters that can also help in distinguishing the subtypes.RESULTS: One hundred twenty-one (85.2%) cases had AIDP, 15 (10.6%) had acute motor axonal neuropathy, and 6 (4.2%) were unclassifiable.CONCLUSIONS: Motor conduction blocks and temporal dispersion could be observed from days 3 and 5 onward, respectively. Progression of motor conduction slowing in AIDP was most impressive in the median nerves. Varying affection of deep tendon reflexes, cranial nerves, and cerebrospinal fluid albuminocytological dissociation can also help make a distinction between AIDP and acute motor axonal neuropathy. Sural sparing, a marker of demyelinating neuropathy, is more commonly seen in later than in early stages of AIDP.

    Hereditary spastic paraplegia with a thin corpus callosum
    (PEDIATRIC RADIOLOGY, 2007)
    We report a 15-year-old boy with autosomal recessive complicated hereditary spastic paraplegia with a thin corpus callosum (HSP-TCC). The involvement of the corpus callosum was characteristic with the genu and body predominantly affected with relative sparing of the splenium. HSP-TCC is being increasingly recognized over a wider geographical area than earlier believed. We now report a case of HSP-TCC from the Indian subcontinent.

    Hyperreflexic Guillain-Barre syndrome.
    (Annals of Indian Academy of Neurology, 2010)
    Guillain-Barre syndrome (GBS) is an acquired acute autoimmune polyradiculoneuropathy. The 2 features considered essential for the diagnosis of GBS are progressive motor weakness and areflexia. There have been several descriptions of reflex preservation and hyperreflexia in axonal variant of GBS in Chinese, Japanese, and European populations but it is not common in the Indian subcontinent. We report 2 such cases discussing the pathophysiology and management aspects. This case report is to impress upon treating physicians and neurologists in training that a hyperreflexic variant of GBS albeit rare, should not be missed in a given clinical setting.
