Surprising Cardiac Magnetic Resonance Imaging Findings: Rapidly Developing Intracardiac Thrombus with Endomyocardial Fibrosis

Introduction

Endomyocardial fibrosis (EMF) is a rare form of restrictive cardiomyopathy, particularly prevalent in tropical regions. This condition is commonly associated with peripheral blood hypereosinophilia, though it may also occur in the absence of such finding. In this report, we describe an unusual case of EMF linked to non-Hodgkin’s lymphoma without hypereosinophilia, accompanied by a rapidly developing intracardiac thrombus.
