Позитронная эмиссионная томография (ПЭТ), совмещенная с компьютерной томографией (ПЭТ/КТ), с радиотрейсерами класса аминокислот часто используется для уточнения природы церебрального поражения, обнаруженного при магнитно-резонансной томографии (МРТ). Базовым принципом диагностики опухоли головного мозга при помощи ПЭТ/КТ с 11С-метионином является гиперфиксации радиотрейсера, топографически совпадающая с участком структурного поражения. Однако высокий захват 11С-метионина не является уникальным признаком опухоли и встречается при ряде неопухолевых заболеваний. В данной работе представлены три наблюдения абсцесса мозга, лучевые проявления которых при МРТ и ПЭТ/КТ с 11С-метионином симулировали злокачественную церебральную опухоль. Причинами обращения пациентов за медицинской помощью послужили судорожные приступы или появление очаговой неврологической симптоматики, а также подозрение на церебральную опухоль по результатам МРТ с контрастированием. Представление о неопухолевых причинах гиперфиксации 11С-метионина и ПЭТ-семиотики этих поражений поможет избежать ошибочной диагностики церебральной опухоли.</p></abstract><trans-abstract xml:lang="en"><p>An increased amino acid metabolism is characteristic for many brain malignancies. Combined positron emission and computed tomography (PET/CT) with radiolabeled amino acids is often used in recognizing the tumor nature of the structural brain lesion detected on MRI. On 11C-methionine PET/CT a hallmark of a brain tumor is an increased amino acid uptake, topographically coinciding with a structural lesion on MRI. However, high 11C-methionine uptake in the brain lesion is not tumor specific and could be seen in a number of non-tumor diseases. The paper presents three observations of a brain abscess, radiological and metabolic data of which in MRI and 11C-methionine PET/CT simulated a malignant cerebral tumor. The reasons for patients seeking nuclear medicine examination were seizures or focal neurological symptoms, as well as a suspicion of a cerebral tumor based on the contrast-enhanced MRI. Knowledge of the non-tumor disease characterized by high 11C-methionine uptake will help avoid misdiagnosis of a cerebral tumor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>озитронная эмиссионная томография</kwd><kwd>11С-метионин</kwd><kwd>абсцесс мозга</kwd></kwd-group><kwd-group xml:lang="en"><kwd>positron emission tomography</kwd><kwd>11C-methionine</kwd><kwd>brain abscess</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">Planas A.M., Prenant C., Mazoyer B.M, Comar D., Reiko Nakajima R., Kimura K., Abe K., Sakai Sh. 11C-methionine PET/CT findings in benign brain disease // Jpn.
