Hemangioma of the rib is a rare benign vascular tumor. Herein, we report a 63-year-old man presenting with hemangioma of the left sixth rib. An osteolytic eccentric expansive mass with calcification and focal cortical disruption was detected on chest computed tomography (CT). The mass showed low 2-deoxy-2-[18F]-fluoro-D-glucose (18F-FDG) avidity on positron emission tomography. The patient underwent resection of the left sixth rib. Based on the histopathology findings, a diagnosis of cavernous hemangioma was made. Rib hemangiomas and malignant lesions appear similar on CT scans; therefore, most cases of rib hemangiomas reported in the literature were treated with rib resection. However, rib hemangiomas should be included in the differential diagnosis of an asymptomatic patient if an osteolytic expansive lesion containing sunburst calcifications with low 18F-FDG avidity is observed on a CT scan.
肋骨血管瘤是一种罕见的良性血管肿瘤。在此，我们报告一名63岁男性患有左第六肋骨血管瘤。胸部计算机断层扫描（CT）检测到一个溶骨性偏心性膨胀性肿块，伴有钙化和局灶性皮质破坏。该肿块在正电子发射断层扫描上显示低2-脱氧-2-[18F]-氟-D-葡萄糖（18F-FDG）摄取。患者接受了左第六肋骨切除术。根据组织病理学结果，诊断为海绵状血管瘤。肋骨血管瘤和恶性病变在CT扫描上表现相似；因此，文献中报道的大多数肋骨血管瘤病例都接受了肋骨切除术。然而，如果在CT扫描中观察到一个溶骨性膨胀性病变，伴有日光放射状钙化且18F-FDG摄取低，则肋骨血管瘤应列入无症状患者的鉴别诊断。
