Abstract
Symptoms of neuromuscular dysfunction are quite common in patients with hypothyroidism. Structural changes of myelin and dysfunction of oligodendroglial processes in axons have pathogenetic significance in patients with neuropathies against the background of hypothyroidism. However, the etiopathogenesis of the development of neuropathies in hypothyroidism is not fully understood. Magnetic resonance imaging (MRI) is a modern imaging method that now provides an image of nerve trunks with a quality sufficient to assess their condition. The main task of MRI is to assess the difficult and atypical cases of nerve compression. We examined 26 patients diagnosed with hypothyroidism, including 8 patients with degenerative-dystrophic diseases of the spine, 1 patient — an anomaly of nerves and muscles, 2 patients were found to have the consequences of injuries, 1 patient was diagnosed with De-Kervin disease, and 14 patients with comorbidity, leading to nerve compression, was not found. The aim of the study was to assess the diagnostic capabilities of magnetic resonance imaging for compression-ischemic neuropathies of the hands in patients with hypothyroidism. Neurological examination and data from stimulation electroneuromyography allows you to accurately determine the area of investigation for MRI. The article shows the diagnostic capabilities of MRI, as well as its place in the diagnostic algorithm of compression-ischemic neuropathies of the hands in patients with hypothyroidism.

Summary
Структурные изменения миелина и дисфункция олигодендроглиальных процессов в аксонах имеют патогенетическое значение у пациентов с невропатиями на фоне гипотиреоза. Магнитно-резонансная томография (МРТ) — современный метод визуализации, позволяющий получить изображение стволов нервов с качеством, достаточным для оценки их состояния. Основная задача МРТ заключается в визуализации нервного ствола и оценке трудных и атипичных случаев компрессии нерва. Целью исследования была оценка диагностических возможностей МРТ при компрессионно-ишемических невропатиях рук у пациентов с гипотиреозом. Неврологическое обследование и данные стимуляционной электронейромиографии (ЭНМГ) позволяют точно определить зону исследования для МРТ. Посвященные изучению возможностей МРТ в диагностике периферических нейропатий, имеют единичный характер. В статье показаны диагностические возможности МРТ, а также ее место в диагностическом алгоритме компрессионно-ишемических невропатий рук у пациентов с гипотиреозом. Ключевые слова: туннельная невропатия, гипотиреоз, стимуляционная электронейромиография, срединный нерв, синдром запястного канала, магнитно-резонансная томография
