RESUMEN
Thymoma is the most common neoplasm in the anterior mediastinum, and extrathoracic involvement is rare. Moreover, cystic liver metastasis is extremely rare; few cases have been reported in the literature to date. We report here on a case of cystic liver metastasis of thymoma treated with surgical resection, describing the ultrasonography, CT and MRI findings.

Cholangiocarcinomas have several histologic types, but intrahepatic cholangiocarcinoma with sarcomatous change is rare. A 71-year-old man was admitted to our hospital because of fever which had lasted two months. Ultrasonography (US) of the upper abdomen demonstrated a huge hepatic mass with central solid and peripheral cystic portions, and computed tomography (CT) revealed a heterogeneous hepatic mass with a central area in which enhancedment was delayed. Magnetic resonance imaging (MRI) disclosed a huge mass of predominantly low signal intensity at T1WI, and peripheral portions of high signal intensity and a central portion of intermediate signal intensity at T2WI. The pathologic diagnosis was cholangiocarcinoma with sarcomatous change.

Familial adenomatous polyposis and hepatoblastoma are rare conditions; the latter is closely related to the FAP gene. We describe the imaging findings of hepatoblastoma in a patient with polyposis coli.
