Cold allodynia as the presenting symptom in a case of acquired neuromyotonia (Isaacs syndrome) with multiple autoantibodies
We report a patient who presented with severe cold-induced allodynia and hyperhidrosis, and found to have acquired neuromyotonia (Isaacs syndrome) with high voltage-gated potassium channel (VGKC) antibody titre,positive contactin-associated protein 2 (CASPR2) and leucine-rich glioma-inactivated 1 (LGI1) antibodies. The patient also had positive anti-dsDNA and acetylcholine receptor (AChR) antib...
متن کاملAutoantibodies in thymoma-associated myasthenia gravis with myositis or neuromyotonia.
BACKGROUND About 50% of patients with thymoma have paraneoplastic myasthenia gravis (MG). Myositis and myocarditis or neuromyotonia (NMT) will also develop in some. Patients with thymoma-associated MG produce autoantibodies to a variety of neuromuscular antigens, particularly acetylcholine receptor (AChR), titin, skeletal muscle calcium release channel (ryanodine receptor [RyR]), and voltage-ga...
متن کاملIdiopathic ocular neuromyotonia: a neurovascular compression syndrome?
Ocular neuromyotonia in the muscles innervated by the right oculomotor nerve was diagnosed in a patient without a history of radiation therapy. Electromyography of the levator palpebrae showed continuous motor unit activity. Brain MRI disclosed a close contact between the right third cranial nerve and a basilar artery dolichoectasia. The patient partly benefited from carbamazepine therapy. This...
متن کامل[A case of Tolosa-Hunt syndrome presenting ocular neuromyotonia].
A 27-year-old woman noticed diplopia when gazing left and paresthesia of the left face and headache of the left side for 8 months. Abduction and supraduction of the left eye were moderately restricted. Hypoesthesia of the face innervated by the ophthalmic branch of the left trigeminal nerve was detected. Visual disturbance due to optic neuropathy developed 5 months later. MRI with gadolinium re...
متن کاملNeuromyotonia.
Neuromyotonia is a rare condition of spontaneous and continuous muscle fibre activity of peripheral nerve origin. It represents the more severe phenotype of peripheral nerve hyperexcitability, and when acquired is often associated with antibodies to voltage-gated potassium channels. There are no specific published electromyographic or clinical diagnostic criteria for this disorder. This review ...
