В связи с тем, что удлиненная левая доля печени чаще бывает подвержена травмам и, в некоторых случаях, может имитировать подкапсульную гематому селезенки, представляется важным, повысить информированность врачей различных специальностей о разнообразии морфологических вариаций строения печени, в частности об удлиненной левой доле печени, унифицировать подходы к описанию и установить единообразие формулировок для обозначения данной особенности анатомического строения левой доли печени, что позволит снизить риск диагностических ошибок и ошибок при хирургических вмешательствах, особенно при тупой травме живота.</p><p>В статье представлены клинические случаи ультразвукового обследования 10 пациентов различного возраста (от 1 мес. до 38 лет) и пола с впервые выявленной аномалией строения левой доли печени – удлиненная левая доля; проведен анализ отечественной и зарубежной литературы, содержащей сообщения о различных морфологических вариантах строения печени и частоте их встречаемости; предложены сонологические признаки для описания удлиненной левой доли печени; описаны особенности методики ультразвукового исследования удлиненной левой доли печени у детей старше года; изучено разнообразие формулировок у разных авторов при описании данного варианта анатомического строения печени.</p></abstract><trans-abstract xml:lang="en"><p>The elongated left lobe of the liver (saddle liver, saber liver, beaver tail liver, beaver lobe) is one of the types of variant liver anatomy, characterized by the fact that the left lobe extends far beyond the midline of the body, and can come into contact with the spleen and even go above it. Due to the fact that the elongated left lobe of the liver is more often susceptible to injury and, in some cases, can imitate a subcapsular hematoma of the spleen, it seems important to increase the awareness among doctors of various specialties about the variety of morphological variations in the structure of the liver, in particular about the elongated left lobe of the liver, to unify approaches to the description and establish uniformity of wording to designate this feature of the anatomical structure of the left lobe of the liver, which will reduce the risk of diagnostic errors and errors during surgical interventions, especially in cases of blunt abdominal trauma.</p><p>The article presents clinical cases with ultrasound examination of 10 patients of different ages (from 1 month to 38 years) and gender with a newly diagnosed anomaly in the structure of the left lobe of the liver, i.e an elongated left lobe. An analysis of national and foreign literature sources containing reports on various morphological variants of the liver structure and the frequency of their occurrence was carried out. Ultrasound signs were proposed to describe the elongated left lobe of the liver. The features of the ultrasound examination technique for the elongated left lobe of the liver in children older than one year are described. The variety of formulations used by different authors when describing this variant of the anatomical structure of the liver was studied.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>удлиненная левая доля печени</kwd><kwd>седловидная печень</kwd><kwd>«печень хвоста бобра»</kwd><kwd>доля бивера</kwd><kwd>классификация морфологических типов печени</kwd><kwd>особенности ультразвуковой диагностики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elongated left lobe of the liver</kwd><kwd>saddle liver</kwd><kwd>"beaver tail liver"</kwd><kwd>beaver lobe</kwd><kwd>classification of morphological types of the liver</kwd><kwd>features of ultrasound diagnostics</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">Khanduri S, Malik S, Khan N, Singh H, Rehman M.
