Среди одиночных образований в легких, не требующих активного хирургического лечения, особое место занимает гамартома: неоднородность структуры за счет включений жировой плотности и кальцинатов представляет возможность для выделения патогномоничных скиалогических признаков. Однако их отсутствие в совокупности с компьютерно-томографической (КТ) картиной, присущей в том числе и злокачественным новообразованиям, может стать причиной проведения биопсий и оперативных вмешательств, необязательных по результатам гистологического исследования.Цель: провести когортный ретроспективный анализ КТ-семиотики легочных гамартом.Материал и методы. Выполнен анализ 142 случаев гамартом легкого, выявленных на базе ФГБУ «Санкт-Петербургский научно-исследовательский институт фтизиопульмонологии» Минздрава России за период с 2013 по 2023 гг., подтвержденных гистологически или с периодом наблюдения более 600 дней, без эндобронхиального расположения и других очагов/образований в легких, без оценки контрастного усиления.Результаты. Описаны результаты статистического анализа данных пациентов с гамартомой легкого с распределением по полу и возрасту. Установлена частота встречаемости таких скиалогических признаков гамартом, как тип образования, особенности контура, изменения в окружающей легочной ткани, наибольший диаметр, плотность, тип кальцинации, с примерами на КТ-снимках. Рассмотрены локализации гамартом относительно легкого, его долей и сегментов. Выделены и проиллюстрированы четыре кластера гамартом в зависимости от сочетания макроскопического жира и участков обызвествления в структуре. Также представлено распределение гамартом из каждого кластера по размеру в заданных диапазонах.Заключение. Гамартомы легких представляют собой образования солидного типа без предпочтительной локализации по сегментам легких, которые могут быть выявлены в любом возрасте. В значительной доле случаев (43,7%) гамартомы не имели каких-либо структурных особенностей, позволяющих по данным КТ убедительно их классифицировать как доброкачественные образования и избежать хирургической резекции. Только в 12% случаев наблюдались структурные изменения, считающиеся высокопатогномоничными для их классификации как доброкачественных образований.</p></abstract><trans-abstract xml:lang="en"><p>Background. Gamartoma occupies a special place among solitary lung masses not requiring active surgical tactics: structural heterogeneity due to inclusions of fat density and calcinates presents an opportunity to identify pathognomonic computed tomographic (CT) signs. However, their absence in conjunction with CT picture inherent in malignant neoplasms can cause biopsies and surgical interventions that are not necessary according to the results of histologic examination.Objective: to perform a cohort retrospective analysis of pulmonary hamartoma CT semiotics.Маterial and methods. We analyzed 142 cases of lung hamartomas detected at the Saint Petersburg Research Institute of Phthisiopulmonology from 2013 to 2023, confirmed histologically or with a follow-up period of more than 600 days, without endobronchial location and other foci/formations in the lungs, without contrast enhancement evaluation.Results. The results of data statistical analysis of patients with pulmonary hamartoma with distribution by gender and age were described. The occurrence rate was established for such hamartoma CT features as mass type, contour features, changes in the surrounding lung tissue, the largest diameter, density, calcination type with examples on CT images. Localizations of hamartomas in relation to the lung, its lobes and segments were considered. Four hamartoma clusters depending on fat and calcination combination in the structure were identified and illustrated. The size distribution of hamartomas from each cluster within the given ranges was also presented.Conclusion. Lung hamartomas are solid-type masses without preferential localization in lung segments, with the possibility of detection at any age. In a significant proportion of cases (43.7%) hamartomas did not have any structural features, which allow, according to CT data, to convincingly classify them as benign masses and avoid surgical resection. Only in 12% of cases hamartomas had structural changes considered highly pathognomonic for their classification as benign masses.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>гамартома легкого</kwd><kwd>одиночное образование легкого</kwd><kwd>жиросодержащее образование легкого</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>pulmonary hamartoma</kwd><kwd>solitary pulmonary nodule</kwd><kwd>fat containing pulmonary nodule</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">WHO Classification of Tumours Editorial Board.
