Abstract

A 54-year-old woman with smoking history who was diagnosed with invasive adenocarcinoma of the rectosigmoid colon with subsequent surgical resection and chemotherapy was presented. The patient developed local recurrence and pulmonary metastases that required further chemotherapy and surgical resection. During follow-up, the patient had 18F-FDG PET/CT scan showing asymmetric hypermetabolic tonsils with activity greater on the right compared with the left. The patient underwent bilateral tonsillectomy, and pathology revealed moderately to poorly differentiated adenocarcinoma in the right tonsil, consistent with metastasis from known colonic primary.
