硬化性肺泡细胞瘤影像学诊断与不典型征象分析

Imaging Diagnosis and Atypical Signs Analysis of Pulmonary Sclerosing Pneumocytoma

硬化性肺泡细胞瘤过去常用名称为肺硬化性血管瘤,是一种肺细胞源性的肿瘤,该病好发于中年女性,多为边界清楚的孤立结节或肿块。近年来随着对其病理特点及影像学表现研究的深入,关于其不典型征象的报道日渐增多,特别是转移和术后复发个例的出现,使得截至目前,其组织学及生物学行为仍未完全确定。此外,18F-FDG PET/CT虽已广泛应用于临床,但较少应用于硬化性肺泡细胞瘤。本文就以上诸方面的研究进展予以综述。

Pulmonary sclerosing pneumocytoma,commonly known as pulmonary sclerosing hemangioma,is a type of lung cell derived tumor that most commonly occurs in middle-aged women and is usually characterized by well-defined solitary nodules or masses.In recent years,with the in-depth study of its pathological characteristics and imaging manifestations,reports on its atypical signs are increasing,especially the emergence of individual cases of metastasis and postoperative recurrence,so that up to now,its histological and biological behavior has not been completely determined.In addition,18F-FDG PET/CT has been widely used in clinic,but rarely in pulmonary sclerosing pneumocytoma.This paper summarizes the research progress of the above aspects.
