Eyelid and Parotid Gland Metastasis of Colorectal Cancer Demonstrated by 18 F-FDG PET/CT.

A 67-year-old man underwent a sigmoid colectomy and received 4 cycles of capecitabine and oxaliplatin. 18 F-FDG was performed for the treatment response evaluation. It revealed increased radiotracer uptake both in the nodular lesion of the left parotid gland and in the subcutaneous density of the left eyelid. These lesions were reported as colorectal carcinoma metastasis in immunohistochemical evaluation. Herein, we present an extremely rare case of simultaneous metastasis of both the eyelid and the left parotid gland in a patient who underwent surgery for colorectal cancer.
