Болезнь Хираяма может быть диагностирована при помощи МРТ-исследования уже на ранних стадиях на основании типичного вентрального смещения задней стенки дурального мешка на высоте переднего сгибания шеи. В настоящей статье представлены два клинических случая болезни Хираяма с различной длительностью заболевания и клиническо-радиологической картиной.</p></abstract><trans-abstract xml:lang="en"><p>Non-progressive juvenile spinal muscular atrophy, also known as Hirayama disease, is a rare form of non-progressive motor neuron disease caused by necrosis of the anterior horns of the lower cervical cord. Magnetic resonance study is able to show forward displacement of the posterior wall of the lower cervical dural canal in neck flexion, which is presumed to be pathognomonic sign of Hirayama disease. Flexion MRI of the cervical spine can help to diagnosis HD in the early stages. We report two cases of Hirayama disease with different disease duration and different clinical and radiological presentation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миелопатия</kwd><kwd>болезнь Хираяма</kwd><kwd>мономелическая амиотрофия</kwd><kwd>МРТ</kwd><kwd>myelopathy</kwd><kwd>Hirayama disease</kwd><kwd>non-progressive juvenile spinal muscular atrophy</kwd><kwd>MRI</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kira J., Ochi H.
