Medullary thyroid carcinoma (MTC) is a rare malignancy which spreads frequently to cervical lymph nodes. We report the CT
findings of MTC metastatic cervical adenopathies in two patients with previously resected MTC. The CT scans showed calcifications
(one patient) and massive homogeneous postcontrast nodal enhancement. Medullary thyroid carcinoma should be included in the
differential diagnosis of entities showing calcifications and intense homogeneous adenopathic enhancement on CT studies.
