Incidentally detected 18 F-FDG PET-CT-avid thyroid nodules in patients with advanced malignancy: long-term oncological outcomes from a single-centre retrospective cohort.

Objectives: In this retrospective study, we assessed the clinical outcomes of patients with a primary malignancy who had incidentally detected thyroid avidity on their staging 18 F-fluorodeoxyglucose PET-computed tomography ( 18 F-FDG PET-CT) examinations.

Methods: A focused retrospective search was made using a Radiology Information System to identify only patients with positive thyroid nodules on their 18 F-FDG PET-CT imaging between January 2012 and December 2017. Patient demographics, principal oncological diagnosis, and stage were recorded.

Small cell rectal cancer: a therapeutic challenge.

A generally well 71-year-old man presented to his general practitioner with altered bowel habit and haematochezia. Colonoscopy revealed a malignant-appearing rectal mass, with histological features of extrapulmonary small cell carcinoma (EPSCC) of the rectum. Imaging demonstrated limited stage disease with a threatened circumferential resection margin.
