A unique case of bilateral ventricular infiltration by lung adenocarcinoma with paraneoplastic hypereosinophilia

Abstract

Key message Existence of poorly differentiated tumour cells or paraneoplastic hypereosinophilia indicates extensive disease progression and poor prognosis in patients with malignancy. When these conditions are present, it is necessary to consider the possibility of intracardiac metastasis even in cases of lung adenocarcinoma.
