Yolk sac tumor (YST) is a rare and highly malignant germ cell tumor that is extremely rare in the nasal region. Herein, we present a case of biopsy-proven nasal YST admixed with transitional cell carcinoma in a 58-year-old woman. Complementary F-FDG PET/CT revealed the only FDG-avid mass in the right nasal cavity. This case indicates that YST could occur in the nasal region primarily, and F-FDG PET/CT is a useful tool to distinguish between primary and metastatic lesions.
卵黄囊瘤(YST)是一种罕见且高度恶性的生殖细胞肿瘤,在鼻腔区域极为罕见。在此,我们报告了一例经活检证实的混合有移行细胞癌的 58 岁女性鼻腔 YST 病例。补充 F-FDG PET/CT 显示右侧鼻腔内唯一的 FDG 摄取肿块。本病例表明 YST 可能主要发生在鼻腔区域,而 F-FDG PET/CT 是区分原发性和转移性病变的有用工具。
