Huge Primary Cardiac Malignant Lymphoma in the Left Ventricle

Primary Cardiac Lymphoma Arising from Both Sides of the Heart

Primary cardiac lymphomas (PCLs) are extremely rare tumors with a poor prognosis. They usually involve the pericardium and the right side of the heart. PCLs arising from the left side of the heart are relatively rare, with bilateral cases being even rarer. We herein report a case of PCL arising from both the right and left sides of the heart in a 65-year-old man. Multiple imaging modalities clearly demonstrated the tumors at the initial evaluation. The pathological diagnosis was diffuse large B-cell lymphoma.

Differential diagnosis of cardiac tumors: General consideration and echocardiographic approach

Cardiac tumors may be primary (either benign or malignant) or secondary (malignant) and are first detected by echocardiography in most cases. The cardiologist often challenges their identification, the differential diagnosis and the best therapeutic approach. Malignant tumors have usually a poor prognosis, which may be significantly improved by appropriate and timely therapies. The echocardiographic aspects of benign and malignant cardiac tumors described in this article, along with a clinical evaluation may orient the differential diagnosis and aid in choosing the further steps useful to define the nature of the mass.

The diagnosis of a giant cardiac malignant lymphoma in the right ventricle: a case report

Cardiac lymphoma is extremely rare in patients with normal immune function and difficult to identify through routine examinations in patients with atypical clinical manifestations, making early diagnosis very difficult. We reported a 71‐year‐old male patient who was repeatedly diagnosed of pulmonary infection, suspected lung tumour, and Kimura disease in other hospital due to cough, expectoration, and dyspnoea. Later on, the patient visited our hospital due to heart failure and epistaxis. Transthoracic echocardiogram confirmed the presence of a space‐occupying lesion in the right heart, cardiac magnetic resonance imaging preliminarily determined the nature of this lesion, finally, ¹⁸F‐fluorodeoxyglucose positron‐emission tomography/computed tomography, and nasal mass biopsy confirmed the diagnosis of cardiac malignant lymphoma, and the pathological type was diffuse large B‐cell lymphoma.
