Synchronous lung and liver metastases from medullary thyroid carcinoma

Metastatic disease is one of the most common causes of calcified nodules in the lung or liver. The incidence of calcified metastasis mainly to the lung and liver is high at the initial presentation in patients with medullary thyroid carcinoma. Synchronous calcified metastasis in the lung and liver is reported for the first time. The diagnosis of medullary thyroid carcinoma may be evident from the synchronous presence of miliary calcified nodules in two different sites if they are associated with high concentrations of serum markers.
