Abstract

Although some histological features of solitary fibrous tumor are related to its aggressive behavior, tumors with benign features may also follow an aggressive behavior. An 18-year-old male patient was referred after the detection of multiple bilateral pulmonary lesions on a chest x-ray in a health examination 2 months ago. These lesions showed inhomogeneous enhancement on enhanced CT and intense FDG uptake (SUVmax, 21.8) on PET/CT. CT-guided biopsy revealed histologically benign solitary fibrous tumor.

摘要

虽然孤立性纤维瘤的一些组织学特征与其侵袭性行为有关，但具有良性特征的肿瘤也可能表现出侵袭性行为。一名 18 岁男性患者在 2 个月前的健康体检中胸部 X 线检查发现多发双侧肺部病变后被转来。这些病变在增强 CT 上表现为不均匀强化，在 PET/CT 上摄取 FDG 明显（SUVmax，21.8）。CT 引导下活检显示为组织学良性孤立性纤维瘤。
