Computed tomography of the chest revealed new multifocal bilateral ground-glass opacities and consolidations with smooth interlobular septal thickening, superimposed pulmonary edema, and moderate bilateral pleural effusions with bibasilar atelectasis (Fig. 1).
A, Section of myocardium showing cyst form of Toxoplasma organisms in an individual myocardial fiber. The interstitial space between myocardial fibers is edematous. (Hematoxylin & Eosin stain, magnification 200X) B, Section of myocardium showing dispersed merozoite forms of Toxoplasma organisms causing destruction of myocardial fibers. (Hematoxylin & Eosin stain, magnification 200X) C, Immunostaining confirms the diagnosis of cardiac Toxoplasmosis. Individual merozoites are identified as stained with the Toxoplasma antibody. (Magnification 200X).

On higher power examination (200X and 400X magnification) random individual myocardial fibers were involved by minute cyst forms of Toxoplasma gondii organisms (Fig. 2A). Toxoplasma (Fig. 2B). The diagnosis of cardiac toxoplasmosis was confirmed by immunostaining (Fig. 2C). The immunostaining was done using Rabbit Polyclonal antibody to Toxoplasma gondii (Cell Marque, 1:200 dilution with Optiview Detection kit on Ventana Benchmark ultra-platform).
