We present a case of a 63-year-old hematologic patient with pulmonary vaso-invasive zygomycosis with Rhizomucor pusillus after a second stem cell transplantation (SCT) for myelodysplastic syndrome, complicated by multi organ failure, myocardial ischemia and infarction. Zygomycosis is common in immunocompromised patients, especially after hematopoietic stem cell transplantation (HSCT). Mucor species have devastating vaso-invasive properties causing hematogenic dissemination. Antemortem diagnosis may be difficult due to negative cultures. Despite adequate treatment outcome tends to be poor. Cardiac zygomycosis is rare. In our patient, the clinical course and imaging results of the myocardial infarction are most consistent with coronary plaque rupture possibly provoked by severe vaso-invasive pulmonary infection and multi-organ failure.
