Abstract

Metastasis of colorectal adenocarcinoma to the larynx is a very rare condition. Here, we report a 72-year-old woman with a history of rectal adenocarcinoma. She was referred for whole-body FDG PET/CT scanning because of an elevating serum level of carcinoembryonic antigen. PET images showed focally increased FDG accumulation in the larynx (SUVmax=12.9). Coregistered CT images showed mild wall thickening at the left subglottic area. The findings of after excisional biopsy confirmed that this FDG-avid lesion was metastatic adenocarcinoma of the colorectal origin.

摘要

结直肠腺癌转移至喉部是一种非常罕见的情况。在此，我们报告一例 72 岁女性，既往有直肠腺癌病史。因癌胚抗原（CEA）水平升高，行全身氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（FDG PET/CT）检查。PET 图像显示喉部局灶性 FDG 摄取增加（SUVmax=12.9）。与 CT 图像融合显示左侧声门下区轻度壁增厚。切除活检结果证实该 FDG 摄取病变为结直肠来源的转移性腺癌。
