摘要：
胃肠道滤泡树突状细胞肉瘤是一种罕见的恶性肿瘤。本文描述了一例具有肝转移的空肠滤泡树突状细胞肉瘤的增强CT和FDG PET/CT结果。原发性空肠肿瘤在增强CT上显示不均匀强化，FDG PET/CT显示强烈的FDG摄取，类似于腺癌或胃肠道间质瘤。肝转移性肿瘤在增强CT上显示低血供，FDG PET/CT显示轻度FDG摄取。该病例提示滤泡树突状细胞肉瘤应该包括在代谢亢进型肠道病变的鉴别诊断中。版权所有 © 2023 Wolters Kluwer Health，Inc. 保留所有权利。
Follicular dendritic cell sarcoma of the gastrointestinal tract is a rare malignancy. We describe contrast-enhanced CT and FDG PET/CT findings in a case of jejunal follicular dendritic cell sarcoma with hepatic metastasis. The primary jejunal tumor showed inhomogeneous enhancement on contrast-enhanced CT and intense FDG uptake on PET/CT mimicking adenocarcinoma or gastrointestinal stromal tumor. The hepatic metastatic tumor showed hypovascularity on contrast-enhanced CT and mild FDG uptake on PET/CT. This case indicates that follicular dendritic cell sarcoma should be included in the differential diagnosis of the hypermetabolic intestinal lesions.Copyright © 2023 Wolters Kluwer Health, Inc.
