title: Hepatocellular carcinoma with mediastinal and pericardial invasion: report of two cases.
abstract: Mediastinal invasion with pericardial involvement in hepatocellular carcinoma (HCC) is rarely described. We report two patients with hepatitis-C-related HCC, who, after several courses of transcatheter arterial chemoembolization (TACE), developed mediastinal and pericardial neoplastic growth. Both patients presented with clinical manifestations of exertional dyspnea, chest pain and orthopnea. The diagnosis of HCC with pericardial involvement, through direct invasion of the anterior mediastinum, was established by computerized tomography and magnetic resonance imaging. These patients' symptoms were relieved after they received radiotherapy with a total dosage of 3,000 and 4,000 cGy over a three-week and four-week period, respectively. We suggest that direct mediastinal invasion with pericardial involvement should be considered when evaluating patients with advanced HCC who developed precordial distress following palliative TACE. Early recognition of this unusual complication is important in the management of HCC.
