[Hypothyroid neuropathy. Description 2 cases]

Although neurological complications of hypothyroidism are well recognized, scanty data, to the best of our knowledge, are available about peripheral neuropathies in this condition. The electrographic studies so far performed are nearly all devoted to the well known association myxoedema-carpal tunnel syndrome. Our data concern two patients affected by neuropathy in hypothyroidism, presenting diffuse anomalies of electrographic parameters (motor and sensitive nerve conduction velocity, F-wave, H-reflex, H-index); and, in one of these cases, a marked segmental demyelination and axonal degenerations were disclosed by pathological examination of sural nerve (according to Dyck and Lambert, 1970; Shirabe and coll., 1975).
