Thyroid metastatic tumors are a series of rare clinical disease with an incidence of approximately 1.4-3%, of which metastatic tumor from the digestive system is even rarer. Thyroid metastatic tumor from the digestive system is characterized by a rapid growth tumor with high invasiveness and poor prognosis. Ultrasound (US) and contrast-enhanced ultrasound (CEUS) could provide more information for making diagnosis, determining lesion range, and offering biopsy guidance. Ultrasound-guided core needle biopsy (CNB) should be used instead of fine needle aspiration (FNA) to confirm the pathological diagnosis. Here, we report two cases of thyroid metastatic tumor from the digestive system. By describing these cases, we aimed to assess the clinical value of conventional US and CEUS in the diagnosis and treatment of these tumors.
