Left ventricular endocardial calcification in a patient with myeloproliferative disease.

摘要

The case of a 57-year-old male with a history significant for myeloproliferative disease, chronic renal failure, hypertension, and prostate cancer is described. His complete blood count was remarkable for neutrophilia and, notably, eosinophilia. Subsequent to two syncopal episodes, a transthoracic echocardiogram was performed as part of the workup, which showed an unusual calcified mass in the left ventricular apical region but separate from the apical myocardium, with normal left ventricular systolic function. A transesophageal echocardiogram and computed tomography of the chest confirmed the presence of extensive calcification in the left ventricle of unusual location and shape. This patient probably had Loeffler endocarditis related to myeloproliferative disorder, complicated by calcification of the endocardial sclerotic lesions.
