ABSTRACT
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.

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.

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.
