44 year old female complained of neck swelling for many years. She is otherwise asymptomatic. Ultrasound showed both lobes are enlarged, heterogenous with solid and cystic lesions. There is a 2.7cm complex cyst at the lower pole of the right lobe. There is a semi-solid 2cm mass at the lower pol of left lobe. There is a 1.3cm solid mass at the isthmus. Findings are consistent with multi-nodular goitre.
