Non-Hodgkin's lymphoma related eosinophilic endomyocardial disease.

Two patients with eosinophilic endomyocardial disease related to peripheral T-cell lymphomas are reported. Both patients were free of cardiac symptoms at presentation and during follow-up. Routine two dimensional echocardiography revealed bi-apical ventricular obliteration, which was also seen on MR imaging. On the T1-weighted sequence, the thickened endocardium appeared with an isointense signal. Gadolinium DOTA provided an enhanced contrast of the internal part of the left ventricular wall. On T2-weighted sequence, a thin hypointense curvilinear structure drew a dividing line between the internal, endocardial, and the external, myocardial area. Left-ventricular systolic and diastolic functions remained unaltered during subsequent follow-up.
