Abstract

Follicular dendritic cell sarcoma is a very rare neoplasm, which is not lymphoma, but originates from a type of immune cells called follicular dendritic cells. We presented a 37-year-old woman who has suffered from obstructive jaundice, weight loss and right upper abdominal pain for 2 months. The contrast CT revealed masses located in the region of pancreatic head and lots of enlarged retroperitoneal lymph nodes, both of which were enhanced on the artery phase of CT images. Meanwhile, Tc-HYNIC-TOC SPECT/CT revealed high activity in the corresponding lesions. After biopsy, the masses were pathologically confirmed as retroperitoneal follicular dendritic cell sarcoma.

摘要

滤泡树突状细胞肉瘤是一种非常罕见的肿瘤，它不是淋巴瘤，而是来源于一种称为滤泡树突状细胞的免疫细胞。我们报告了一位 37 岁的女性患者，她患有阻塞性黄疸、体重减轻和右上腹痛 2 个月。对比 CT 显示肿块位于胰头部区域，大量腹膜后淋巴结肿大，两者在 CT 图像的动脉期均有增强。同时，Tc-HYNIC-TOC SPECT/CT 显示相应病变部位有高活性。活检后，肿块被病理证实为腹膜后滤泡树突状细胞肉瘤。
