摘要

淋巴肉芽肿病（LYG）累及主肺动脉（MPA）极为罕见。我们描述了一例源自 MPA 的 LYG 患者的氟-18-氟脱氧葡萄糖（18F-FDG）正电子发射断层扫描/计算机断层扫描（PET/CT）结果。氟-18-FDG正电子发射断层扫描/计算机断层扫描（PET/CT）显示，MPA内有结节状高代谢灶，与CT肺血管造影的管腔内充盈缺损十分吻合，并观察到继发性右心功能不全。经导管 MPA 活检和多学科会诊后，最终确诊该病。患者在接受类固醇治疗和MPA支架植入术后完全康复，第二次18F-FDG PET/CT显示了这一点。

18F-FDG PET/CT characterization and response evaluation in a case of lymphomatoid granulomatosis involving the main pulmonary artery.

Main pulmonary artery (MPA) involvement of lymphomatoid granulomatosis (LYG) is extremely rare. We described fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) findings in a case with LYG originated from the MPA. Fluorine-18-FDG PET/CT demonstrated nodular hypermetabolic foci in the MPA, corresponding well to the intraluminal filling defects on CT pulmonary angiography, and the secondary right heart dysfunction was observed. Final diagnosis was made after transcatheter MPA biopsies and multi-disciplinary consultation. The patient recovered completely following the steroid therapy and MPA stenting, which was illustrated on the second 18F-FDG PET/CT.

期刊介绍： The Hellenic Journal of Nuclear Medicine published by the Hellenic Society of Nuclear Medicine in Thessaloniki, aims to contribute to research, to education and cover the scientific and professional interests of physicians, in the field of nuclear medicine and in medicine in general. The journal may publish papers of nuclear medicine and also papers that refer to related subjects as dosimetry, computer science, targeting of gene expression, radioimmunoassay, radiation protection, biology, cell trafficking, related historical brief reviews and other related subjects. Original papers are preferred. The journal may after special agreement publish supplements covering important subjects, dully reviewed and subscripted separately.
