ABSTRACT: Mediastinal ectopic thyroid is quite rare, occurring in less than 1%
of all ectopic thyroids. Frequent location of mediastinal ectopic thyroid in reported cases is
anterosuperior mediastinum. CT findings of ectopic thyroid can be various and
are dependent on several factors, such as its iodine content, the extent of tissue
degeneration, and the presence of colloid cysts. This is a case of right
paratracheal ectopic thyroid with nodular hyperplasia, mimicking metastatic
nodal mass on both CT and 18F-FDG
PET CT in a patient with colon cancer.
