Abstract
Hibernoma is a rare benign but metabolically active tumor of brown fat origin, that can have cross-sectional imaging characteristics similar to those of other fat-containing tumors, such as lipomas and liposarcomas, and its presence can lead to false-positive interpretation by exhibiting increased F18-fluorodeoxyglucose (F18-FDG) activity. A 46-year-old woman was diagnosed with dermatofibrosarcoma protuberans underwent F18-FDG positron emission tomography/computed tomography (PET/CT) for detecting recurrence after excision. F18-FDG PET/CT showed incidental intense uptake in the back in addition to increased F18-FDG uptake at the previous lesion site. To our knowledge, this is the first case report of intense F18-FDG uptake in hibernoma in Korea.
摘要
冬眠瘤是一种罕见的起源于棕色脂肪的良性但代谢活跃的肿瘤，其在横断面成像上的特征可能与其他含脂肪肿瘤（如脂肪瘤和脂肪肉瘤）相似，并且由于其表现出F18-氟脱氧葡萄糖（F18-FDG）活性增加，可能导致假阳性解读。一名46岁诊断为隆突性皮肤纤维肉瘤的女性在切除术后接受F18-FDG正电子发射断层扫描/计算机断层扫描（PET/CT）以检测复发情况。F18-FDG PET/CT显示除了先前病变部位F18-FDG摄取增加外，背部还意外出现强烈摄取。据我们所知，这是韩国首例关于冬眠瘤中F18-FDG强烈摄取的病例报告。
