Magnetic resonance imaging in rabies.

Rabies encephalitis has a classical clinical presentation and its diagnosis is unmistakable. In about a fifth of cases rabies occurs as its paralytic form, which lacks the classic symptoms and may mimic other diseases, especially acute disseminated encephalomyelitis (ADEM). Magnetic resonance imaging of the brain in rabies shows a distinct abnormal pattern that differentiates it from ADEM. Hence it may be a useful tool in diagnosis of paralytic rabies. Failure to administer post-exposure rabies immunoglobulin along with the rabies vaccine may result in vaccine failure.

Recurrent Miller fisher syndrome: a case report.

Miller fisher syndrome (MFS) is a variant of Guillain-Barre syndrome characterized by the triad of ophthalmoplegia, ataxia and areflexia. Recurrences are exceptional with MFS. A case with two episodes of MFS within four years is reported. He presented with findings of ophthalmoplegia, ataxia, areflexia, and oropharyngeal weakness and mild distal sensory impairment during both episodes. Electrophysiological findings showed reduced compound muscle action potentials and sensory nerve action potentials with no evidence of conduction blocks. Nerve biopsy showed segmental demyelination. MRI of brain was normal. He responded well to immunoglobulins during both episodes suggesting that immunomodulating drugs have a role in the treatment of MFS.

Hemiballismus due to an ipsilateral striatal haemorrhage: an unusual localization.

Hemiballismus has been correlated clinico-anatomically with lesions of the contralateral side, most commonly of the subthalamic nucleus. Hemiballismus due to an ipsilateral lesion is extremely rare. We report the case of a 55 year old female who developed a right sided hemiballismus due to a right striatal haemorrhage, which simultaneously caused a left hemiplegia. The hemiballismus subsided on treatment with dopamine-blockers over the next two weeks.

Delayed onset generalised dystonia after cyanide poisoning.

A 27 year old female developed delayed onset of persistent generalized dystonia following a suicidal attempt with potassium cyanide. Cranial CT scan showed bilateral putaminal hypodensities which were also seen on MRI scans to be hypointense on T1 and hyperintense on T2 weighted images. Multimodality evoked potentials were normal. An improvement was noted with levodopa.

Extrinsic infratentorial lesion causing ataxic hemiparesis--a new localization.

The case of an 18-year-old woman is reported who had developed progressive inability to use her left limbs since the age of 13 years. Ataxic hemiparesis was noted on the left side. A CT scan of the brain revealed a non-enhancing hypodense lesion in the cerebellopontine angle with a supratentorial extension consistent with an epidermoid. Ataxic hemiparesis has previously been reported only with intrinsic lesions of the brain, except for one case. An unusual clinical localization of this entity is reported.
