Hypofractionated radiation therapy of a thyroid tumor in a pet raccoon (.

Thyroid neoplasia has been documented in raccoons; however, successful management and treatment has not been well-described. A 15-year-old, intact female pet raccoon was examined for evaluation of a right-sided ventral cervical mass and a cough of 4 to 5 mo duration. Cytology and computed tomography (CT) findings of the mass were most consistent with a thyroid tumor.
