Myokymia in a Patient with Chronic Inflammatory Demyelinating Polyradiculoneuropathy.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired, immune-mediated neuropathy affecting peripheral nerves and nerve roots. It is characterized by symmetric weakness involving both proximal and distal muscles; it can be relapsing-remitting or progressive in course. The clinical manifestations of CIDP are various and may present with atypical features, like myokymia, tremor, or tremor-like phenomena, which may mislead the clinician in diagnosis.

Polyradiculopathy and Multiple Cranial Nerve Palsies - Rare Manifestations of Cerebral Venous Sinus Thrombosis.

We report about two young males who developed significant proximal weakness of all four limbs secondary to intracranial hypertension due to intracranial venous sinus thrombosis. Intracranial venous sinus thrombosis can manifest in a variety of ways which includes isolated intracranial hypertension, focal neurological symptoms or signs and acute or subacute encephalopathy. Various false localising signs have been reported to occur in patients with raised intracranial pressure including cranial nerve palsies and extensive radiculopathy.
